Description Valentin Heidelberger univentionstaff 2017-05-05 16:37:32 CEST 
It would be nice to have fail2ban integrated into UCS to block IPs which cause too many sasl authentication failures. 
This is a symptom of spam networks trying to get into mail accounts to use the mail server for spamming.

A how to guide on doing this would also be nice.

There is a Customer ID set so I set the flag "Enterprise Customer affected".
