[courier-users] Virtual Hosting Setup / Securing Relaying of Mail

[James House]

Hi all,

I'm new to Courier and fairly new to SMTP servers in general.

Can some one give me some quick pointers on what options I need to set up in Courier to get the following behavior:

Scenario:

1) Courier server running on machine: mail.aaa.com
2) Courier server "knows" about several virtual domains, say bbb.com and ccc.com.
3) Mail users are non-system accounts (i.e. setup in GDBM) - [EMAIL PROTECTED]
4) User "joe" checks and sends mail from his home ISP (xxx.com)

How do I:

1) Allow "joe" (who has an account on the Courier server) to relay mail from his home computer (using some IP address from his dial-up ISP account), using a client such as Eudora/Outlook/Evolution

2) Disallow "dick" to relay mail from his computer on some unknown network to domains that the Courier server isn't serving.

3) Allow "dick" (some unknown computer on some unknown network) to send mail to "[EMAIL PROTECTED]" (an account hosted on the Courier server)


In other words, how do I let anyone relay mail (from external networks), as long as they can "authenticate", and disallow relaying if they can't, but still allow posting as long as it is to a local account?

If I set up authenticated ESMTP relaying, does that do the trick? - or does it stop un-authenticated external senders from sending mail to local accounts? (I guess I'm unsure if sending mail to a local account is "relaying")

Thanks,
James
