> I don't know if anyone on this list can give me a hand, but I'm trying to configure sendmail on our library's LAMP server. I have to use a different IP address specifically used for outgoing email instead of the box's IP. Does anyone know where/how I can configure this?
I don't know how to do this in sendmail since we configure our servers
to use postfix, but in postfix's main.cf, there's a variable called
smtp_bind_address = 111.222.333.444
that lets you specify the email origination IP. If your machine
doesn't really do much mailing, you might consider switching to
postfix since it's a lot easier to run and can be used as a drop in
replacement for sendmail and many of your favorite sendmail commands
work just fine with it.
If you need to add an IP to your NIC as well
may be of use to you assuming you're on linux.
