MailEnable POP debug log file error:

(recv) socket [692] error during [RETR] command from host x.x.x.x. Socket was disconnected - Error: (10060)

Windows firewall running in the Windows background on the MailEnable server can cause intermittant problems when retrieving messages.

CAUSE

Windows firewall is running in the Windows background on the MailEnable server and is filtering incoming connections on port 110. Some messages may contain malicious content which may trigger the windows firewall filter and can cause the MailEnable POP service connection to timeout.

RESOLUTION

Add an exception to the Windows firewall for the MailEnable POP service and port 110.

Or alternatively disable the Windows firewall from within the Windows/firewall options and disable the Windows firewall service under the services list.
