Some ISP monitor the outgoing messages for spam detection. For example,
Cogent, if an IP sends some amount Spams (IIRC 10) they will charge the
downstream VPS company $20.

Implement a policy that if big amounts of spam are going out you can
immediately block outgoing port 25.
Is there anything commonly used for monitoring the level of outbound
SMTP? Or are vendors forcing all outbound through an egress server to
scan everything, or homerolling wireshark, tcpdump, web flo scripts.
You'd need to be able to break down which unit is generating the spam.
