This is happening a lot since I switched from Courier to Dovecot and when the 11.40 version happened.

I need to know how to fix this issue because it affecting the incoming email of my customers.


Reason: TCP Transaction Log:

Maximum Size of a Authentication Process (MB) to 128M
Maximum Number of Authentication Processes to 70
