Is it possible to use Courier to create a 'smart' mail relay?
What I want is a mail server that can reject mail to non-existent users
based on it's userdb, but then send the good mail along to another
server for delivery.
From what I can tell by reading the man pages, I can't use esmtproutes
to send the mail to another server if the mail is local, but if the mail
is not local, then it won't check the usernames. Is there any way
around this?
Not sure about this but what about using aliases? So let's say that you are
"relay.example.com" and you are the primary MX for "example.com" and you want
to send the mail onto mail.example.com. So you would put "example.com" into
locals and esmtpacceptmailfor and then create aliases like
us...@example.com: user...@mail.example.com
Now you have no accounts on your system but you accept mail for example.com if
there's a valid alias which will in turn ship it out to mail.example.com.
As I said, I haven't thought this through really well but it seems to me that
this would work.
