[Mimedefang] scanning outgoing mail

[Cliff Hayes]

Hello,

Mimedefang and Spamassassin are doing a fine job of scanning incoming mail
on incoming MX servers.
I have the MX servers feeding a POP3 server.  How would I scan outgoing mail
to stop infected senders?  Do I use mimedefang for that or just
spamassassin?

Thanks in advance,

Cliff
