I am facing a problem with my email POP3 Login..

I am using Browsegate 2.80 [Work] as proxy and configure the same for POP3 also.

but when any user in my LAN network connect this POP3 server through MS Outlook, they can't login to POP3 Server, while they can do outgoing mail. but they can't access incoming mails.

I have tried to change port also 110 to 111 but MS Outlook can't connect POP3 Server.

Please Help me, I am in trouble.
