ssullivan,

The names/email addresses int he "to" and "from" headers are not the "real" recipient's and sender's email addresses - they are just text content that is inserted into the email's headers. They can match or mismatch the actual to/from addresses that mail servers act upon, depending on how the sender formats the email. When using the blacklist/whitelist filters to check addresses and domains, SpamFilter will only look at the real sender and recipient's addresses as specified in the MAIL FROM and RCPT TO smtp command. SpamFilter does not check the email addresses contained in the headers, as they can be easily faked.

This said, you can use the keyword filter to perform keyword searches against those headers, and thus look for the name in the "To:" header.

By default SpamFilter will not scan the headers for keywords, but you can use the following setting in the SpamFilter.ini file to change this behavior:

;if ScanAllHeaders is set to 1 SpamFilter will add all email's headers to the text examined for keywords and statistical Bayesian searches.

ScanAllHeaders=0

Okay that explains one part to this, but if the domain is not on the whotelist how can I block by just the Name that come across in the To field.

The whitelist would take priority over all blacklists.  As soon as any condition for whitelist is found the message is allowed in.]]> Wed, 24 Feb 2010 23:35:36 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6804&PID=13460&title=filter-by-the-name-in-the-to#13460 <![CDATA[Filter by the Name in the To : The other catch to this would...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6804&PID=13459&title=filter-by-the-name-in-the-to#13459 Author: ssullivan

The other catch to this would be.  If I allowed the Domain (i.e. yahoo.com) in a white list but was blocking it Name in the To (i.e. MyBigOne).  Which one takes happens?]]> Wed, 24 Feb 2010 10:18:31 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6804&PID=13459&title=filter-by-the-name-in-the-to#13459 <![CDATA[Filter by the Name in the To : I have been seeing some spam that...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6804&PID=13458&title=filter-by-the-name-in-the-to#13458 Author: ssullivan

I have been seeing some spam that has been coming in.  The name in the To field is the same but the email address it is tied to changes.  IE MyBigOne [jdoe@aol.com], MyBigOne [Janed@hotmail.com].  I would like to block it by name on the To (i.e. MyBigOne*).  How can I do this?]]> Tue, 23 Feb 2010 23:30:59 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=6804&PID=13458&title=filter-by-the-name-in-the-to#13458
