POP3 Proxy not working

Hello,

we have any issue with using POP3 Proxy and Exchange 2010.

From time to time it happens that our external ticket system is not able to connect to our POP3.
Also telnet connection to port 110 from external is not working.

I don't see any problems with our mailserver as telnet from internal network to Exchange is working, also other mail traffic is working without any problems.

Restart of POP3 Proxy on ASG also doesn't help.

Is there any idea where the problem is located ?

Regards
Steffen

Hi, Steffen, and welcome to the User BB!

Your question confuses me. Normally, the POP3 proxy is used by internal clients accessing an external POP3 server. What configuration do you have that allows, at times, an external client to access an internal server?
