Email problems after upgarding: "imapd-ssl: Unexpected SSL connection shutdown."

[DanijelD]

I just upgraded from 9.5 to 11.0 last night.
I have problems with email when I connect via Outlook. I gets disconnected from server, and can't sync folders and messages. Then it connects again. Very randomly.

In the mail log I noticed the problem:

"imapd-ssl: Unexpected SSL connection shutdown."

This happens often.

What could cause this?

Still very annoying... any idea how to fix?

Should I maybe reinstall whole currier imap? How to do it?

I'm guessing incoming and outgoing mail server is setup correctly in Outlook.

Try to type in "cmd" or "terminal":
# telnet <YOUR_DOMAIN> 25
(you need to type QUIT - uppercase to exit if you connect)

If you connect successfully, that means default port (25) for outgoing mail server is enabled and you should be able to setup email account in Outlook with no problem. If you fail with "telnet", check in Plesk if port 25 is enabled, if it is, and you still are unabled to connect, try to open different port and then try to setup your mail account.

As i mention in one other topic on the forum, in my country 95% of internet providers are blocking standard port 25, so i had to open a new one.

Problem is not that I can't connect. Problem is that I connect but suddenly get disconnected. This happens randomly, usualy while Outlook is syncing folders.

I didn't see problems with other clients.

All worked ok before the Plesk upgrade.

Any idea?

Well, i don't have any specific, but as you mentioned now, if it works for all clients and it happens only to you randomly, problem might be something else. Try to dig deeper in logs and wait for IgorG to reply or some expert like he is. Good luck with solving problem.

Thanks, but that's not it.

I used Outlook for years, and this started happening yesterday after I upgraded Plesk from 9.5 to 11.0.

Outlook just randomly disconnects or gets disconnected from the server...

I even re-generated Certificates, since I googled that could be a problem, but no, that didn't help neither.


Is there a way to reinstall courier-imap or to re-config at least?

Outlook is reporting error "0x800CCC0E".
