Re: [Declude.JunkMail] Filter for blank subject lines

True.  Just be careful, and understand that you can't apply such actions to whitelisted E-mail.

So if he builds his rules appropriately, either as a specific domain rule or a combo filter, he should be able to apply the subject requirement to his own users/domain without affecting or bouncing messages to anyone outside his userbase/domain.

It's called backscatter, and it is a very large problem, typically amounting to 1% to 2% of my total mail volume. This is also common enough that you would also upset many customers. If you tweak your setup properly, you can tag blank subjects with a little weight and still not have issues with blocking legitimate E-mail while improving spam detection. Matt [EMAIL PROTECTED] wrote: Any previous talk on filtering for blank subject lines is 2 years old, so I'd like to present the question again, and/or make a new feature request. Within our corp, we have several employees who enjoy send their mails with no subject what-so-ever. Wrist slaps have done nothing to correct this problem. I'd like very much to bounce mails lacking subjects, informing the sender that to complete the delivery, they must resend with a completed subject line. I've tried using both SUBJECTCHARS and CONTSPACES, but they don't seem to work as I'd like. Is there a specific test or filter I can use to detect blank subject lines?
