[SUMMARY] RE: Masquerading Domain Name

Sincere thanks to Dan Lowe and Sergio, yes Sergio, I wanted to set the reply
to to nabeel@bose.com. I am in the process of setting up that mailbox.

The solution as per Sergio:
In your .mc file (you do generate your .cf from a .mc, don't you?) you
simply need to add a line that reads
FEATURE(`masquerade_envelope')

In standard sendmail 8.9.3, this adds a couple of rules to S94.

If you want to do it by hand, notice that the header and envelope
sender addresses go through a slightly different sequence of rulesets.
You need to make sure that the envelope sender is passed through the
same ruleset (S93 in my case) that does masquerading for the header
sender. In m4/proto.m4, I see

###################################################################
###  Ruleset 94 -- convert envelope names to masqueraded form   ###
###################################################################

S94
ifdef(`_MASQUERADE_ENVELOPE_',
`R$+                    $@ $>93 $1',
`R$* < @ *LOCAL* > $*   $: $1 < @ $j . > $2')

If Solaris sendmail doesn't offer these configuration options,
junk it and install the latest sendmail from www.sendmail.org.
Or another MTA like qmail (www.qmail.org) or postfix (www.postfix.org).

(We used to run locally-compiled sendmail 8.9.3, but recently
switched to qmail 1.03.)

The solution as per Dan:
 set up reverse DNS if possible.

If not, try configuring whatever is sending mail to send it as such:

  /usr/lib/sendmail -fnabeel@bose.com

Or it might be:

  /usr/lib/sendmail -oi -oem -fnabeel@bose.com


The only problem with this one was that it didnt allow me to set a subject
on the commandline which mailx enabled me to do and which the script was
using.

Thanks all,
Nabeel

Hi,

My email goes out as nabeel@gemini.bose.com
It gets rejected from a couple of places who use reverse lookup. So, I need
to make sure that it goes out as nabeel@bose.com

So, far I have configured DM in sendmail.cf The DM value is bose.com
What it does is now, when I send a message, it shows the address in the from
field as nabeel@bose.com, however, if I monitor the output using sendmail -v
to send the mail, it is still sending the mails as nabeel@gemini.bose.com

What other fields do I need to change?

Thanks,
Nabeel
