Hi,
we have problem with access thgrough SMTP, IMAP, POP3 protocols in CAS 2013.
If I test connection to SMTP 25 port from other computer, session end quickly.
Test from CAS2013 to localhost or public IP is OK (similar also for IMAP and POP3).
Receive connectors are with defaults settings, firewall is disabled.
Service Microsoft Frontend Transport Services restarted, but no success.
Certificate is assigned to IMAP, POP3, SMTP, IIS.
IIS and HTTP(s), protocols are OK. Clients can connects only thgrough web, mobile (ActiveSync), or with Outlook with proxy.
Do you have some tip, what to test?
If I create new testing receive connector on port 26 for anonymous, behaviour is same, quick disconnecting.
Thank's Mirek
