It's not about blocking spam, it's about forcing employees to be sensible when it comes to electronic messages. I myself get between 20 - 30 emails a day from 1 employee that carry blank subjects. Dare I say 700 a month from one person? Memos, personal requests, outside of ramming their head into a file cabinet, I have tried it all. Then you have remote users who I don't have the pleasure of beating on daily. You want to talk about a very large problem... I'd love to have 1% or 2% of my messages with no subject line. As it stands right now, this very second, 20% of my corporate inbox is filled with messages that have blank subject lines. That's a very large problem. You want to come here a sift through 100 random e-mails trying to find something?
I am fully aware of problem with bouncing mail and forged headers. But using the test or filter intra-domain will have no adverse effects on yours, or anyone's server... only mine. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Matt Sent: Wednesday, January 05, 2005 2:35 PM To: Declude.JunkMail@declude.com Subject: Re: [Declude.JunkMail] Filter for blank subject lines Since a sizeable amount of blank subjects are spam and come from forged addresses, please don't bounce such messages. 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.
