Though I understand you are providing an example of what you meant, perhaps it would have been better to rename it "16e547f1.w95-hybris-worm-exe" or something similar, instead of sending a live copy of it unaltered to the mailing list. Then again, the majority here read from mutt etc, so risk is pretty minimal. OTOH, If people are crazy enough to unknown attachments in unknown emails, as well as not using an Antivirus program on windows.. well... hehe. Regardless, You may want to take a look at Amavis, Qmail-Scanner, or some of the other scanning options available. http://www.qmail.org/top.html#microsoft HBDEV offers a free license for their antivirus program on *nix, as long as it's for personal use. It seems to work well, and I believe both Amavis and Qmail-Scanner support it. I know this doesn't address your question of 'how do I block relayed mail with a blank from field', but perhaps you will still find it somewhat useful. - Jamyn At 11:02 AM 5/10/01 +0300, you wrote: >*** DO NOT OPEN THE ATTACHMENT*** > >Our e-mail users receive lots of e-mails with no subject nor from adress but >just an attachment.
