Subject: SSL_accept failure sometimes, with Outlook on imap 993 SSL
I have installed citadel on a debian 8 server. Imap is SSL 993, and SSL certificates are configured using let's encrypt.
Using Mozilla Thunderbird, syncing on my IMAP account works flawlessly everytime.
However, using Microsoft Outlook, sometimes (1/3 times) I get an error 0x800CCC0E when attempting to sync.
On the server side, in /var/log/daemon.log, I get
imap SSL_accept failed: retval=-1, errval=1, err=error:00000001:lib(0):func(0):reason(1)
Now, error 1 is SSL_ERROR_SSL, but I can't seem to be able to get more information.
Retrying usually works. Many of my users will be using Outlook to connect.
Thank you for your help!
