Hi, >> The only people that have said great things about the antispam capabilities of Imail Server Plus have been IPSwitch employees as far as I can remember. <<
Well, one important factor is that all these spam checks happen AFTER the mail has already been accepted. Now you have a dilemma if you THINK you have spam. Either just hold/delete it and hope that it wasn't a false positive - because now the sender AND recipient of the possibly important email have no notice that it's stuck. Or, you end up sending bounce messages - which, in 99% of the cases, will be sent to an innocent Internet user whose email address was falsified. The CORRECT approach is of course to offer admins to block connections for many tests and/or when a certain combinaton of tests have failed. Per example, I have a policy to drop connections when SFP fails, when the sender IP is a listy open proxy, when the mail from is an non-email domain, when email is sent to postmaster@ AND to other recipients, when emails from <> is sent to MORE than one recipient, has no RevDNS (same as AOL does), etc. etc. While this may result in false positives - at least the SENDING mail server WILL have notice that the connection did not succeed and if it's a LEGIT sender, WILL notify the TRUE sender of the issue - without me having to risk sending "spam". In adddition, Sniffer, Virus Scan and other content checks can be performed BEFORE at the end of DATA and a 5xx rather than a 2xx can be returned. Without that, the Imail Spam checks don't do me any good.

Plain old Imail server works great with an antispam proxy or a gateway in front of it. Imgate is a good solution if you have a spare box to install it on and Len can give you support. On the other hand, if you want to just add to your existing Imail server you can install the opensource ASSP. It has a very active community and does wonders for an overworked Imail server. It does a tremendous job identifying/blocking spam. The only people that have said great things about the antispam capabilities of Imail Server Plus have been IPSwitch employees as far as I can remember. Someone else chime in here if I am mistaken please.
