"Connection refused" error and ISE while trying to enable POP3 polling


I’m facing issue when trying to enable pop3 polling with private email server.
Mailer is configured correctly – we tested it on other client programs, as well as when working with gmail.

When I try to switch on “Poll via POP3 for email replies.” I receive ISE:

Here is info from logs (not so much):

I tried connecting to pop3s (ssl) on 995 and pop3 (starttls) on 110 port - both with no success.

The version I use 2.6.0.beta1 ( 67a310db02 )

Any help please?


Any help please? Please let me know if I need to provide any additional info in order to resolve this issue. Lot of users can’t answer by email because of this issue…


This is a problem with your mail configuration - search the web for “connection refused” diagnosis steps.
