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.
