I have a new Zimbra server built and am able to get users externally to use secure pop3 on 995. We have a number of machine internally that want to connect via standard pop3 on 110. I can telnet on to see the server is ready on 110 but when trying to connect via outlook for example it just keeps looping popping up a box asking for user name and password.
If i can it to secure 995 its fine but not standard. Can anyone advise
