We've been adding "attachment_renamed.txt" to attachments ending in .exe,
.bat, .pif etc for some time now and no-one's complained. We use a fairly
simple procmail rule to do it but then we were already using procmail to
deliver messages.

We're trying MailScanner (http://www.mailscanner.info/) which scans e-mails
for viruses and can use SpamAssassin to tag spam. As others have said,
blocking what something automatic decides is spam may cause grief as one
man's spam is another man's news (or Dilbert cartoon!) I don't think it's
been integrated with Postfix yet though.
