I am working on a Windows 2008 R2 server running Exchange 2010 and I am currently trying to troubleshoot a POP3 connectivity issue that is preventing some outside remote accounts from logging into the mail server. The certificates are valid and I have verified from ExchangeShell. I have also the correct Exchange cert CN as the x509 certificate name. As well as verified the POP3 service is running also from ExchangeShell.
I cannot get a POP3 OK from a telnet session via running telnet localhost 110
.
The only thing I am returned is:
220 <localhost> Microsoft ESMTP MAIL Service ready at <date> -0500
Any ideas?
