Hello,

I have a client that would like to block e-mails to a mailinglist containing smileys etc from hotmail, yahoo a.s.o.

We tried to make a block on the link where the smiley are loaded from.
Ex.: "graphics.hotmail.com" or "emsmile.gif"

This does not seem to work. The filter is only scanning the "body" of the e-mail and not the source.

Any good suggestions for our problem?

Thanks in advance!
 
Hello,

I don't believe the filters are smart enough to do html parsing. It should just be any text that's in the raw email. What may be happening (just a guess) is there might be a limit to the size of the data that the filter will actually scan. So if the word you're searching for is after that point (for large emails) then it might not get scanned... but I haven't really heard of that so not sure if it applies or not.

Beyond that, check the /etc/virtual/domain.com/filter to see exactly how the filter is being saved to disk. Try filtering without any periods, spaces, etc.. in case they're being treated differently (like wildcards or something, like in a perl regex)... so try just blocking the word:

emsmile

and confirm in the email source that it's there, and not encoded in some other fashion (view email source).

You could also try manually setting the filter file for testing purposes to see what does and doesn't work. Just keep in mind any changes made through DA would overwrite that, so it would be for testing only.
