Filtering outbound mail

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. Customer mail
