Issue using TLS for SMTP and POP

Post by PaulJ »

We have MailEnable enterprise v10 and have got TLS working fine for our internal users (i.e when they connect via our LAN to the mail server).

However when we get people coming in externally it does not work, we get a timeout message. I suspect that our Firewall is doing something however is there anything within MailEnable that might need a tweak to cope with this? Messages in the POP debug when we test it are:

03/14/18 00:02:06 [1232] SSL recv failed: 10060.
03/14/18 00:02:06 [1232] SSL_Handshake negotiation failed

Which indicates MailEnable is terminating the connection

Hi,

There is no TLS support for POP. You can only configure the email client to connect using SSL. The logs don't specifically indicate MailEnable dropped the connection. It simply stated that that there was a timeout between the server and client. Ensure that you have configured your email client to connect to the POP service on the SSL port. Also that you have a valid SSL certificate configured within MailEnable and set the POP service to require SSL on the port your connecting to.
