I am currebtly using Sendmail 8.8.6 on an i486 Linux box with Slakware 3.1 installed. Any user (user@linux.my.domain) can receive their email and also any email going to a virtual domain (user@virtual.domain). My problem is, when I send an email to user@virtual.domain, the user receives the email but the "TO:" in the header information is rewritten as user@linux.my.domain!
    Does anyone know how to stop Sendmail from rewriting the "TO:" field in the header?

Greatly appreciated!

Yup... DNS is forward looking up the IP address of your virtual
host to a certain IP.  So when the mail comes to that IP, your
sendmail catches it, not knowing that it was destined for your
virtual domain.

The trick is to tell sendmail to listen for it.
In /etc/sendmail.cf, make sure there is a line that looks like:
Fw/etc/sendmail.cw

Then in /etc/sendmail.cw put the following on seperate lines:
yourdomain.com
mail.yourdomain.com
virtualdomain.com

....etc., you get the idea - basically any domains you want
sendmail to catch mail for.  Be sure to kill sendmail, and
then restart it (with "sendmail -bd") after you have added
the entries to /etc/sendmail.cw

Not the solution you were looking for? Getting a personalized solution is easy.
