Hi there,

I haven't had success blocking a blank subject with a simple RegEx statement.  However, I am curious as to whether you may now be able to do this with a liberal use of the new BlockBlankEmailsWithAttachments setting in SpamFilter.ini (available in versions 3.5.4.701 and above).

I can't test it out, because I don't have the latest version.  But try this in SpamFilter.ini:

BlockBlankEmailsWithAttachments=*

But then again, this may still require that at least some attachment is included with the message... I don't know.

See this post for more information on the new setting.

Stephen
