IMail AntiSpam seems to have a lot of bugs related to the DNS blacklist. The following cases seem to be not categorized as spam even though the URL is in the url black list:
- if <a href> or <img src> is partially or fully in upper case (like "<A href>" or "<A HREF>") - if the domain name does not end with a "/" but with a different char (like http://someurl.com?rid=12245) - if between the "<a" start-of-tag and the actual "href=..." part are carriage returns - if there is a (bogus or not) user name specified (like http://[EMAIL PROTECTED]/blah) These are the cases I found out where the URL domain black list is simply not triggered. I use rules now to remove the spam messages that gets most often through. BTW, I informed IMail about these problems, and they said, they are looking into it in future versions. If they won't, the antispam filter would get weaker and weaker, since a lot of spam mailers now use such tricks since many antispam filters have problems with said problems as well. >-----Urspr�ngliche Nachricht----- >Von: [EMAIL PROTECTED] >[mailto:[EMAIL PROTECTED] Im Auftrag von Mike Biddle >Gesendet: Montag, 19.
