[Mimedefang] blocking | and bad syntax in from address
Hi all, I've been noticing a lot of spam coming in with characters in the from address that don't work or are likely to be forged. These cause a backup in our outbound queue (lots of NDRs) so I'd rather they be rejected right off the bat. from=[EMAIL PROTECTED] from=Puri|[EMAIL PROTECTED] from=Rauly|[EMAIL PROTECTED] from=[EMAIL PROTECTED] from=80/[EMAIL PROTECTED] from=A/[EMAIL PROTECTED] Do any of the rfc's say this is improper syntax or forbiden characters? Should I block this? Can I block it? And if so can someone recommend a good way to do it?

I've never looked at his code, but it seems to work decently on my home mail server (which doesn't need mimedefang's flexibility). --Paul Heinlein [EMAIL PROTECTED] ___ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [EMAIL PROTECTED] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
