The key is to use the right tests (the "right" tests are different for different people). For example, we strongly discourage people from using the BADWHOIS test (run by http://www.rfc-ignorant.org ), as it blocks a lot of legitimate mail (it lists several TLDs such as uk and us). Then there are other tests that you almost certainly should use, such as the BADHEADERS test, which will catch a lot of spam but won't catch any legitimate E-mail (except mail coming from broken E-mail clients, but those could easily get discarded elsewhere anyways). >I have not yet subscribed to the MAPS RBL, DUL, RSS (or MAPS+) services, >and wonder if these might be the key lookups to making JunkMail effective >for use with IMail.

We are happy to give you advice on the settings to use. The problem is that different people have different needs. Different domains tend to get different types of spam, depending on how long the domain has been used, where the addresses have been used, and so forth. We do have a list of the DNS-based tests and some information on each of them at http://www.declude.com/junkmail/support/ip4r.htm , but nobody seems to have a list that includes information such as what % of spam they are catching, if any legitimate mail is getting caught, and so forth -- so we just don't have access to that kind of information. Our two usual suggetions are either [1] Check the Declude JunkMail logs to see what tests are failing, to get an idea of which tests are most useful to you, or [2] subscribe to the Declude JunkMail mailing list and see what others are using/suggesting (you can send an E-mail to [EMAIL PROTECTED] with "subscribe declude.junkmail Your Name" in the body to join). > I would >appreciated any comments from other users of the product. > >Thanks, >Michael > > > >Please visit http://www.ipswitch.com/support/mailing-lists.html >to be removed from this list. > >An Archive of this list is available at: >http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
