Hello Sun Managers, Here is my summary of replies into unix based mail servers. I had quite a few comments on both Lotus Notes and the I-Planet software, along with several "try and fix your exchange server" and a couple of mail servers my research before posting the question did not turn up. And, only one vacation message, so that appears to be getting better. I also want to thank the following people who sent their experiences to me as posted below, plus anyone I forgot: Eric Watson Suresh Rajagopalan Dave Brady Toby A. Rider Eric De Mund Clements, Ian Dan.Anderson Chris Cariffe Phil Brutsche Michael DeSimone David Meissner Edwin Groenescheij Kevin Colagio Ric Anderson Eric Shafto Arvinder_Dadhwal Hendrik Visage Clift Robert T CONT DLVA Bruce Cannon Jeff Kennedy Tim Chipman John Marrett Mika Tuupola Jernej Zajc Am Thursday, 28.

Global address lists would be available via LDAP. It is not the same as with exchange, but should suffice. +++++++++++++++++++++++++++++++++++ I feel your pain. I came from a sendmail/IMAP environment, and am now stuck using Lotus Notes on my Sun. It is, without a doubt, the *worst* e-mail client I have ever used. The Microsoft Windows client might be better, but the Solaris one is a piece of junk. It will occassionally freeze your window manager. It will suck the color palette dry. It has *no* filtering capability (that I can find; I miss procmail!), and rigidly controls message composition. (Ex. The line with your name at the top is not editable or removable.) You don't have permission to create other folders. Keyboard control is nil. You must use the mouse for almost everything. It's atrocious. +++++++++++++++++++++++++++++++++++ This is what I have done at 3 different places. Use an Exchange server for the calendaring, etc.. and make it forward smtp to The Sun box running Qmail, sendmail, postfix, or whatever MTA you like. The users can then pop or imap their mail off the Unix box. You can give them the option of storing their mail on the server. Then you can then write some scripts to email them when they have too much mail saved on the mail server. +++++++++++++++++++++++++++++++++++ Count me as a "me too"; I'd also like to know this. If you send out a summary email, I'd appreciate a copy. +++++++++++++++++++++++++++++++++++ Sounds like you have a bunch of people running windows clients already. Just convert them back to Internet Mail Service and have them use IMAP on their Windows clients. This way, they keep most of the features you want (except calendaring and the other crap but that's easily solved with Meeting Maker or Synchronize. +++++++++++++++++++++++++++++++++++ Notes is alright. I still protect/support mine with a little solaris/sendmail mx server though. +++++++++++++++++++++++++++++++++++ i have installed and used netscape or i-planet stuff. i would recommend this. ease of use and install as well! +++++++++++++++++++++++++++++++++++ Nor does it work worth a crap when it is up :) Seems like most of the mail system interaction problems I run across at work are caused by MS Exchange. I won't tell you the horror stories I've heard out of some universities what switched to Exchange... Yesterday, my boss had had enough of the ms mail system and approached me about upgrading to a unix based in-house mail system. Immediately, thoughts of glee filled my head and the possibility of bringing another Sun box in house and loading up the latest copy of SENDMAIL and IMAP. Sendmail? Exim (or Postfix) + Courier IMAP, baby :) Unfortunately, I quickly realized that this system will not only be used by techies but also sales people, management and secretaries who want/need fancy formatting, fonts, colors, calendars, address books, etc.... I can not present a solution that will cause these people to loose these features that they already have. The "fancy formatting" (fonts, colors, etc) generally is not a problem - that's just HTML email, and is well supported by at least the 4 or 5 Windows email clients I can name right off the top of my head (OE, Outlook, Netscape, Pegasus, Eudora). Sendmail (or whatever MTA you use) won't be able to tell whether the message has formatting or not, nor will it care. It's all just text; what the email client does with that text is what makes the difference. You might be able to replace the address book functionality with LDAP, but it won't work anything like what the others at your company are used to. There are a number of third-party schedule mechanisms. One of the things people like about Outlook+Exchange is it's ability to integrate all that functionality into one interface. So, to the point, I am curious what Unix server based email systems the group is using in house and if you would recommend it to someone else. I do believe that Lotus makes a version of Notes for Solaris and that Netscape has Suite Spot, or what ever it is being called now. But I don't have experience with these, hence this request for your experience. I would say Lotus Notes. HP's OpenMail *might* be an option, but I wouldn't want anyone else to subject themselves to that particular hell, and HP is dropping support for it anyways. I don't know anything about Suite Spot. What we use in house: Exim + UofW IMAP + OpenLDAP. We have no need to share schedules/calanders. +++++++++++++++++++++++++++++++++++ Intermail (now openwave mail) or post.off from (what was software.com ) and is now http://www.openwave.com/ look in products Communication Services and Additional products. Netscape stuff is OK as well. Non techies can still use Outlook and send and make appointments, just not see other's calendars. No out of the box Global address book either. The rest of that stuff is client based and they can still do. +++++++++++++++++++++++++++++++++++ I love Unix and I use it for everything that I can, including my own mail, but it's too much to ask of people to give up an e-mail system that they're used to and perhaps comfortable with. It's pretty painful for regular users to switch from Exchange to Notes, or to a Unix-based system. Exchange can be stable enough for a small company despite the occasional reboots and the difficulty of doing restores. My advice is to put some resources into stabilizing your Exchange installation. Perhaps reinstall it on better hardware, upgrade to the latest version, etc. +++++++++++++++++++++++++++++++++++ You might wanna download the iPlanet Messaging Server 5.1 and the iPlanet Calendar Server 5.0 (evaluation versions available from http://www.iplanet.com/). I have installed iMS 5.0 for an ISP in Australia and it works quite well although we ran into some bugs, version 5.1 seems to have solved most of the bugs. In combination with iPlanet Delegated Administrator even MCSE's are able to create domains, e-mail users, mailing lists etc etc. About 6 months ago I played a bit with a beta version of iCS 5.0 it looked very good but haven't done a real install for a customer yet. +++++++++++++++++++++++++++++++++++ Simply put, let everyone use it as a pop or IMAP server....their client end will interpret everything as it should, and the Unix backend (with sendmail) won't care. Sendmail delivers to a Unix mailbox. Pop clients (and IMAP I think...no real experience there) can just look at the server's mailboxes and interpret what they see there. Sendmail doesn't care about content...only the clients do. Hope that helps, now go get a decent new Sun box with the latest version of Sendmail! +++++++++++++++++++++++++++++++++++ Where I work we use UW's imap client with sendmail. Desktop users (mostly windows 2000) use Outlook and its address book or netscape and its address book. Calendering is done via a program called meeting maker (http://www.meetingmaker.com) which runs on a novell or windows server (I forget which, as its run by another group). This combo gives the PC folks a nice GUI interface, and (if they use netscape) palm pilot/visor conduits for address books. Meeting Maker also includes a Palm conduit. +++++++++++++++++++++++++++++++++++ You can still use Outlook (bleah) as your mail client if you're not using an Exchange server. You'll lose some nice features, like the ability to retract messages before they've been read, group calendaring, etc. Outlook (Outlook 2000, anyway) is very comfortable using rtf to send richly-formatted email, and there should be no problems sending that through a standard smtp server. If you're willing to spend a reasonably small amount of money, I might suggest Communigate Pro. It's a dream to set up and manage, it provides a decent web-mail interface, handles pop and imap, along with their secure variants, and it's rock-solid. I understand that it scales well, too, but I never used it for more than like 500 accounts. If you want to go the hard way but you're not a masochist, consider qmail, which is simpler to set up than Sendmail, also free, reasonably well supported, and is written beautifully. Well, efficiently and securely, anyway. You'll have to add your own imap server, but there are how-to's for that. I did it with Cyrus and it didn't take me more than a day to integrate them, and most of that was reading FAQ's. qmail's got a couple of stupid gotchas, though, so do read all the readme's or you'll spend time banging your head unnecessarily. Or just install sendmail. +++++++++++++++++++++++++++++++++++ Okay, so why not Groupwise? Great product, full-featured, admittedly a bear to administer, but not nearly as bad as Exchange. You won't get what you want from a straightup smtp server, although I did move people happily from Exchange to a combination of Communigate Pro (see my previous email) and WebEvent, which is a nice shared web calendar. Doesn't do the really cool stuff like scheduling meetings, but it was for a school and they really needed more of a community calendar. +++++++++++++++++++++++++++++++++++ Lotus Notes do make it for solaris too. I have worked on Notes on NT, administering them and it has been great working on it. Here one of our client has Notes riding on AIX RS/6000 and it's working absolutely fine with no major problems. Administering Notes is a breeze compared to Exchange. +++++++++++++++++++++++++++++++++++ Let's start at the begining: Email: Setup Qmail/postfix/sendmail etc. as MTA (Your choice depends on logging features, speed and ease of config) Make use of imap/pop3 for the connection from server to client. The "Fancy formating and Word Documents" will only be a problem for the people reading/writing email on text based consoles (ie. Mutt ;^), but Netscape as well as Outlook (express also) supports the sending of MIME and HTML formatted email. Calendering: This is the "tough one". The issue here is that M$ did some thinking by integrating email & calendering, for this integration you'll have to start looking at Notes etc. However, NEtscape do have a Calendering solution available. Address book: Netscape do provide that (WIfe using it @home). SOmething that's "interesting" about M$'s exchange, is that the adress book is accessible via LDAP (using it @work to get ext numbers from exchange while on a Unix server :) That said, DO take a look at freshmeat.net, there are quite a few browser based options available that do have some integration of it all. +++++++++++++++++++++++++++++++++++ check out StarOffice..... +++++++++++++++++++++++++++++++++++ An optimized solution for an enterprise, including enterprise calendaring, shareable calendars and mail/message folders and other conveniences that I have implemented has been a (Sun-based, but Linux will work) sendmail box in the DMZ with aliases for all the users, and the Exchange server on the LAN, or in the LAN Servers segment setup to use the sendmail box for internet mail. Putting an Exchange server, even behind a firewall, out on the internet is a tempting target. Also, you'll find that on the rare occasions your Exchange server hangs, the mail for your users will still be in the sendmail box, and will dump its queue to the Exchange server as soon as it comes back up. A proper implementation of Exchange is very, very reliable. The Williams Companies have an enterprise-wide deployment that has been working with no unscheduled downtime for years. The sendmail frontend is the secret. And a lot less painful than migrating users! +++++++++++++++++++++++++++++++++++ alas, it comes down to this: fully integrated "messaging solutions" that include email / calendar / task management with "groupware" capacity to boot are rather more limited in abundance than straightforward email (POP or IMAP) based solutions. Of course, stuff like "fonts, formatting, colours" are *purely* an issue of what E-mail client the person is using. A vanilla POP / SMTP mail server can be used by Eudora, Outlook, Outlook Express, Netscape Messenger (or whatever mail client you want, really) and send "HTML / RTF" email message content that is very "pretty" - with fancy fonts, in-line images / background images, etc etc.. The difficult bit comes along when users demand fully integrated calendar, messaging, task management. Currently, Microsoft has a big edge here since they were in the game quite early with their solution. And of course that all the other "groupware" solutions suck. :-) [or have had this problem in the past :-) ] Sun / Netscape do offer "SIMS", a more-or-less integrated messaging system (email, calendar groupware with some task management) but last time I checked it wasn't perfectly clear to me how well integrated things really were, or what variety of client software was available for this setup. Everything I've ever heard about Lotus Notes/Domino has *always* screamed "WARNING! RUN AWAY NOW! DO NOT LOOK BACK!" -- I've heard tales of horrible stability with the server-side software, let alone the horrible, bloated lotus notes client software. (Lotus notes is really an "Enterprise database management system" that allows fully paperless office type function - and which has the capacity of email, calendaring, groupware -- but it does SO many other things as well .. that if you don't need those extra functions .. be warned .. There are also options with Novell Groupwise, although I am told it has real scaling problems as well once you get over a certain user base size (ie, more than one "post office" system). As an aside: I *hate* to say it - but: what version of exchange are you using, running on what flavour of Windows? If you are not using Windows 2000 .. that is a huge upgrade waiting to happen. Although I think MS is evil in many ways, it cannot be denied that Win2K is a big step up from WinNT4 in many ways. Likewise, I believe that the newest version of Exchange is a major improvement over the NT4 era version of exchange.. so you may want to (have to?) consider this as an option if you are not already running the "newest and greatest" flavour of Exchange/Windows. Ultimately - it may come down to more of a "management decision" in terms of deciding between (high stability and therefore NOT MS ; however fewer groupware features - but good IMAP, SMTP) vs (Abundant groupware features and thus Microsoft). BTW: IMHO Postfix is a much better SMTP server than Sendmail (www.postfix.org) - however I won't try to start a holy war with such a topic here :-) Anyhow. I hope this little blathering rant is of some use. I'll be very interested to hear what you find out at the end of the day.. +++++++++++++++++++++++++++++++++++ Intrested in replacing exchange using a drop in replacement? Check out http://www.openmail.com. I understand HP is planning to kill this product after the next revision. Apparently due to pressure from microsoft. Supposed to be a very interesting product though... +++++++++++++++++++++++++++++++++++ I have had a bit same kind of situation as you do. Some people insisting on having Exchange because of its calendaring features etc. Since Exchange is not an option to anyone who is an admin I wouldnt install it. What I have ended up doing is runnind Sendmail as MTA, Cyrus as IMAP / POP3 server and Steltors (ex CST) Corporate Time Server as Calendaring server. I use Sendmail for two main reasons. I have best experience with it, and I dislike qmail. Postfix could be an option though. Main reason for choosing cyrus was speed. It also handles huge emails (our people are sending and receiving huge attachments via email) really well. You can build a sealed system with cyrus since mailboxes dont need to have corresponding unix accounts. Before I installed Cyrus I was warned it was going to be a complicated install. However I think it went together pretty easily. Cyrus can be found at: http://asg.web.cmu.edu/cyrus/imapd/ Corporate Time is basically what makes this system pretty much the same as Exhcange to end user (only this time realiable). CTime provide the calendaring functions. It has native clients for Windows, MacOS and even Motif. It also has a webclient and it can be used via Outlook (you need to install Corporate Time Outlook Connector). To enduser this is just like using the exhange calendar. More bonuses is possibility of syncing your calendar data to Palm, Pocket PC, WIN CE and Psion handhelds. CTime accounts can be stored in internal database or fetched over network from LDAP server. The install was clean and worked straight out (which I was surprised since I have had some bad experiences with commercial software installs on unix). Check Steltors website for more info: http://www.steltor.com/ +++++++++++++++++++++++++++++++++++ Just a thought: a standard unix MTA like qmail/postfix, "rich" mail could be HTML mail that many graphical mailers understand and calendar app could be database driven groupware accessible through PHP from web browser. The first out of dozen solutions from the top of my head.Received on Mon Jul 2 16:16:21 2001
