POP3 connections issues on ZCS community server

Hi,
I am using ZCS 4.0.5_GA_518, encountered POP3 connection issues recently.
There are a couple of errors but am not sure how related are they to the event. Any help to identify the issue and thus prevent it from happening would be great.
thanks,

James
