# Fail2Ban filter for Anti-Spam SMTP Proxy Server (ASSP)
|
||||
# Filter works in theory for both ASSP V1 and V2. Recommended ASSP is V2.5.1 or later.
|
||||
# Support for ASSP V1 ended in 2014 so if you are still running ASSP V1 an immediate upgrade is recommended.

[Definition]
|

# Note: First three failregex matches below are for ASSP V1 with the remaining being designed for V2. Deleting the V1 regex is recommended but I left it in for compatibilty reasons.
