It's been awhile since I've configured sendmail on OpenBSD,
so I'm hoping I didn't botch the procedure too badly.
Read the "Masquerading and Relaying" section from
/usr/share/sendmail/README,
You'll most likely want to use the following features on your external
systems:
FEATURE(`MASQUERADE_AS', `domain.com')
FEATURE(`MASQUERADE_ENVELOPE')
...and this on your main server:
FEATURE(`access_db', `hash -T<TMPF> /etc/mail/access_map')
I see two problems with your desired configuration. All of the
messages from your remote systems are going to appear to be from
senders like [EMAIL PROTECTED], and you're not going to be able to tell
which machine really sent the message unless you read the headers.
Secondly, since some of your machines are on dynamic IP addresses
you're going to have to keep updating the access map. You could just
not use it, but then you can be spammed from remote systems that claim
to be sending mail from domain.com.
