Thanks, it would be a useful feature I think. It would probably only cut out about 2% of the spam but every percent helps.]]> Sun, 05 Feb 2006 17:07:31 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5486&PID=7311&title=regex-blocking-by-date#7311 <![CDATA[RegEx Blocking by Date : Vicer,Currently the email headers...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5486&PID=7310&title=regex-blocking-by-date#7310 Author: LogSat

Vicer,

Currently the email headers cannot be scanned for keywords, so you will not be able to block emails based on the date field. There is an option in the SpamFilter.ini file to scan the "Received:" headers, and we may add add some other options in the future.

Here is the problem. Several Spammers are sending mail with an old date header. Inbound message is from 2003 or 2004 etc. Easy enough to do, a pc has the clock set back and a smtp engine sending mail.

What I want to do is find some way, and probably RegEx is the only way, to block all inbound messages that do not conatin this years date. or go even one step further and if it does not contain this years month and date.

I am a RegEx Nub any help or ideas would be great.
