That's not what I was referring to. It is not a matter of auto-processing all bounced email to set these accounts to inactive* :

Features:
o Manual or auto processing option
o Collect logs via IMAP/POP or mail spool file
o Custom filters to match patterns in bounced emails
o Uses encrypted header for authentication (suggested by Paul M).
o Stats on members with bouncing emails, and error codes
o Tuning options
o Verbose cron logs for diagnostics
o Option to send PM warning prior to reaching the limit
o Option to send PM notifications after reaching the limit
o Option to process 5.0.0/550 errors (email unknown) upon a single email, isntead of observing the bounce limit

*However, I would certainly be most happy with that improvement at the moment.
