[Mimedefang] OFF TOPIC

[Chad Stalvey]

I have a mailserver at domain.com. I'm going to offer Mimedefang as an
optional service. What I want to do is set it up on a different server, say
filter.domain.com, then whoever wants the service will have an alias set up
to forward their mail to that server. Now, I only want the sendmail
connections to come from the server at domain.com. IE: If someone tries to
send a message directly to someone at filter.domain.com, it will not go
through. Is there a way to let sendmail handle this? Or should I not make an
entry in DNS for filter.domain.com and just have it in the hosts file of
domain.com?

Thanks.
