Terry,

If you do not currently have the keyword filter enabled, go ahead and enable it, with at least one keyword in the list.  Even if you were not planning to use the keyword filter, just enable it with a single keyword of sufficient length and randomness, like "bqzxryypmw" or something along these lines that would never actually result in a keyword match.  After doing so, test sending the attachment again and see if the attachment filter is working for you.

The "free trial" version of SpamFilter is always a few release-levels older than the licensed version, and this sometimes means that there may be old bugs in the trialware that have since been fixed in the licensed version.  This particular issue was a bug that occurred in build 302... but was reported to LogSat and quickly fixed in their very next build.  For reference, you might also want to take a look at http://www.logsat.com/sfi-release-notes-and-bug-fixes.asp, and read all of the other enhancements and bug fixes that have occurred since build 302.

Terry,

In the free version there's a bug that has been fixed in later builds:

// New to VersionNumber = '2.0.1.306';
{TODO -cFix : Attachment filtering was not working if keyword list was empty}

That may apply to your case. If that does not help, please email at support@logsat.com your SpamFilter.ini file, along with all your local black/white list files and keyword file(s), a copy of your activity logfile that shows a message not being filtered, and possibly the source of the email so we can try to replicate the problem.
