I am unable to successfully send a message using port 465. I always get this message on outlook
I can see the client trying to connect but I don't know what is going on in the background.
Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: Protocol: SMTP, Port: 465, Secure(SSL): Yes, Error Number: 0x800CCC0F
Any help would be appreciated.
Also is there anyway zimbra can send encrypted emails to other mail servers.
