Hello, everyone!
I have quite a straightforward issue here that I would appreciate any
input on.
I used IP aliasing to set up two IP addresses on my server.. The
primary IP address is used for the MX record for one domain (domain1)
and the secondary one is used for the MX record of another domain
(domain2).
When I use sendmail to send email out the destination servers always
mark the primary IP address of the server as the sender of the email
message. For example,
if I set up sendmail to send emails for domain2 the email headers of
any received mail from domain2 shows the primary IP address of my SMTP
server and not the secondary IP address (the aliased one).
Is this an issue with my IP aliasing (networking issue) or issue with
sendmail - what is it that I have to do to resolve the above situation.
My major goal here is to get receiving servers to understand the email
has come from the secondary IP address and not the primary one.
Thanks for any help in advance!
Roumen.

Roumen,

I think you need to bind sendmail to the specific address you wish.  I
haven't tried this personally, but I think it will work:

Try the following option in your sendmail.mc file.

DAEMON_OPTIONS(`Name=MTA,  Addr=x.x.x.x, Port=smtp)
(specify the appropriate name and address)

Rebuild your sendmail.cf and stop and restart the daemon

Hope this helps.

-Jim

Jim,
thanks a lot for the answer!
Also, I found a good article at
http://ccrma.stanford.edu/~mortimer...n/sendmail.html for those
who are having similar problem.
I also used CLIENT_OPTIONS() in sendmail too but still could not get
the receiving mail server to recognize that the mail was coming from
the secondary aliased IP.
Do you have any idea what else I could be missing?
Thanks a lot again for your help!
Roumen.

Unfortunately I don't know what else could be wrong.  My sendmail experience
is minimal.

Sorry.
