[Dovecot] Dovecot POP3 problem: Authentication suddenly failsuntil dovecot gets restarted

[Carsten Buchenau]

Thank you very much!

I set:

  auth_worker_max_request_count = 10

and I wasn't swamped by 100 emails this morning, so I assume it did the
job.



I received the following though, only once, coming from the POP3 poller
process. I assume this might be a result of Dovecot replying with a
value that the Poller doesn't understand? Due to the limit set with the
config line from above?

Set this to non-zero:

# Number of auth requests to handle before destroying the process. This
may # be useful if PAM plugins leak memory.
#auth_worker_max_request_count = 0
