AW: [suse-security] Filter out bad emails

["Rasp, Robert" <Rob@xxxxxxxxxx>]

Hello,

i know about the patch.
This patch only helps, if qmail is used as server.
I use qmail as relay and virus-protection.
The unwonted mails came from our own Exchange-Server.
Because he wants to tell the (not existing) sender about a not existing
emailadress.

Qmail can be patched to reject unknown recipients.
Postfix or Sendmail or Exim don't need patching, and do this
of-the-shelve.
