We installed IMAIL 8.0 a few weeks ago. We did have some problems where a lot of legitimate e-mail was caught by the statistical filter. We downloaded the new file from Ipswitch which fixed some, but not all.
The stat filter considers most foreign languages spam, as well as a lot of HTML messages with imbedded gifs. We've had to forward e-mail from the spam box for many users due to the stat filter considering too much legit e-mail spam. The reverse DNS is a problem. Many of our legit customers don't have it turned on, so we had to turn it off. Bob -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of R.

You may want to look at the complete (over 100) list of DNS-based spam databases at http://www.declude.com/junkmail/support/ip4r.htm . Note that the FIVETENIGNORE test, which is one of the ones that comes pre-configured with IMail v8, will catch E-mail from some larger ISPs (someone just reported that all Cable and Wireless customers will have their mail caught by that test). >I am hesitant to turn on the reverse DNS lookup as I assume not all >companies have a reverse DNS setup. They are all *required* to have one. AOL is now saying that they may not accept mail from servers with no reverse DNS entry (and for years have counted it strongly in their secret weighting spam system). However, we still find that about 20% of legitimate E-mail comes from mailservers with no reverse DNS entry, so I wouldn't block E-mail *just* based on the lack of a reverse DNS entry. -Scott --- Declude JunkMail: The advanced anti-spam solution for IMail mailservers.
