The only two acceptable settings. They are: - Relay for addresses - should be used with care unless all addresses listed are completely within your control. Addresses listed here should only be INTERNAL IP addresses
- NO Relay - preferred setting - will still allow authentication of Port 25, SSL and 587 Any other setting makes you a playground for spammers and will get you blacklisted. All users must be required to authenticate under all circumstances. 8.20 provides a means to accomplish this via port 587 when port 25 is blocked by an outside ISP.

You've said not to allow anything - regardless of port or authentication. What you want to do is use a null "Contral Access" (or list a few abusive external mailers), and list your local block in "Relay mail for Addresses". With no other relay options, no mail will be relayed unless it's "treated as local" by being listed in the "Addresses" list or by authenticating. hth on 820, I'm on 815 and this is how it works for me. Dan -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Jonas Fornander Sent: Saturday, July 09, 2005 4:06 AM To: [email protected] Subject: [IMail Forum] Need help with configuring anti-spam I thought I understood how to configure Imail with port 587 but now I'm more confused than ever. I hope someone can un-confuse me. This is our setup: Our MX records points to Imgate Our hosting, DSL and dialup users has mail.netwood.net as their outgoing server which is Imail. This server is configured to "Relay for addresses" and our IP blocks are listed. Our Imail is running 8.20 and port 587 is enabled and working. If I change my own account to use port 587 it works if I enable "My outgoing server requires authentication". So everything is working as it should, sooooo now what? I thought that I would be able to go to SMTP Security -> Control Access and deny access for all IP addresses EXCEPT for our trusted IP blocks. Then users on non-trusted IP addresses would be able to send out mail using port 587 it they were authenticated. However if I deny access to a non-trusted IP in SMTP Security -> Control Access then they can't send out mail on port 587 either, even if they authenticate. :-( What am I missing? How can I make our users - on trusted IP addresses - being able to use mail.netwood.net to send out mail and our users - on non-trusted IP addresses - to send out mail on port 587 (with authentication) and ALL other mail, sent directly to the Imail server should be rejected?
