Don't quite understand what your asking help here on. The IMail SMTP server is actually one of the best 'rounded' mail servers I've had the pleasure using. The built in access control list, kill list file (kill.lst), and rules file (rules.ima) are very good spam prevention tools. My suggestion, for Spam and Virus control, would be to port IMail to an IMGate - Declude - FProt combo. I can't recall any SMTP Servers, yet, that have any hardened spam control software as a standard feature. I think your looking at forged headers of the email that spammers so often do. I believe Scott, from Declude, has or is producing an awsome filter for that - check on the http://www.declude.com site for that. IMail supports many, many different features and 'integrations' into other 3rd party programs - review the manaul or at least browse their web site. In the Admin SMTP gui SMTP security at least put check marks in: no mail relay, check valid sender, auto deny possible hack attacks, disable the VRFY command. You'll find pleanty of help and great examples by searching the Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
<quote> No Mail Relay Causes the SMTP server to refuse mail destined for other hosts. If all of your mail users send and receive mail from the same host that IMail Server is on, or if they all use Web Messaging to access mail, you can select the No Mail Relay option. You will still receive mail destined for local users, because a message destined for the IMail Server host or a message originating from the IMail Server host does not use the relay function. You can also use this setting to force your users to authenticate, by selecting "No Mail Relay" and disabling the SMTP AUTH Reporting option. The "No Mail Relay" setting is ignored when SMTP client uses AUTH and mail is relayed anyway. If AUTH is not enabled within the client, it will not relay the message "No Mail Relay is the best option if you cannot "Relay for Addreses" because your users dial up using dynamic IP addresses. 1998-2002 Ipswitch, Inc. </quote> ~Rick > well,i have downloaded a trival version of 7.13. > after installation & configuration,i found SMTP authentication doesn't work exactly.
