Sinds the last update of DirectAdmin (DirectAdmin 1.689) problem with e-mail, Update Direct Admin look like succesfull, but i can not connect the imap server.
The client on my phone as Micrsoft Office Outlook can not connect with the imap server. I can not connect with my email with Roundcube of the server. it look like that there is something changed afther the last update.

When i look in: "Mail Queue Administration", there i see the mail what is hanging and not coming to the mailbox

Hello,

Thank you for the details of your setup. But it is still not clear, why you can not connect to the IMAP server. And what error do you get? Is dovecot running at all? Is it a timeout error? Or TSL/SSL related one?
