Hallo.

I need to run courier on two different IP's. One of them with smtp-auth for outgoing mail, two of them without smtp-auth only for accepting incomming mail. Is it possible to do that without two instances of smtp server ? What is the best way to do that ?

What would be the benefit over just providing all features to all IP-addresses?

cu, Bernd

I would take this problem by the other side... I think Bambera want to force smtp-auth on an interface and let it disable (for incoming mails) on the other ones.

What I would suggest is the following: iptables ! Just block ports you don't want users to connect to.

What is the mechanism that identifies if a mail is incoming or outcoming? Except "Received: " headers, that can be faked, I don't know how to distinguish these two flows

client ==> server ( ==> server) server ==> server ( ==> mailbox)

Am I right in my guesses? HTH. Jerome.
