[BUG] Task paperless_mail.tasks.process_mail_accounts errors if no port is given

[pyfisch]

Describe the bug Exception occurs during the execution of task process mail accounts if no explicit port is chosen.

To Reproduce Steps to reproduce the behavior:

1. Add a new email account, set all required fields and choose "SSL encryption", but don't set the IMAP port.
2. Wait for task paperless_mail.tasks.process_mail_accounts to execute
3. Look up failed tasks in the admin interface, find the most recent execution
4. See error below

Expected behavior Paperless-ng chooses automatically port 143 for unencrypted/STARTLS and port 993 for SSL if the port isn't explicitly given.

I con firm this bug, although it was for me: TimeoutError: [Errno 110] Connection timed out

[pyfisch]

@henfri I use Paperless-ng with Docker, I suspect you aren't based on the error. Is that correct?

[henfri]

I am in fact using Docker as well.

[pyfisch]

Ok, then something else causes different errors.

[henfri]

Well, for me it was the missing port - just like for you.
