To block outbound bursts using SA is probably the most inneficient method.

My mail filters also do a lot of outbound relaying from hundreds
of customer mail servers. Compromised accounts happen and I
have some methods for detecting most of them and block the
sender at the MTA within a few minutes to prevent my server
IPs from becoming listed on RBLs.

Hi folks,
I was wondering if anyone knew of an effective way to filter outbound mail
for spam before it leaves. We're running spamassassin (well, spamd),
sendmail, and spamass-milter. The mail I've tested is being tagged
effectively, but I'm not sure how to then filter it. I've looked at
mailav
It is tempting to avoid filtering outbound mail (with SA or other). I am
assuming that outbound mail is legitimate (users are honest, and logs
can be used to look for abnormal behaviour and punish the guilty).
Now my question. Wouldn't that weaken Bayes filtering? I see two views:
