Sending mail error: already authenticated

[laurentiu2]

Steps to reproduce

1. Reply to a mail

Expected behaviour

The reply should be sent via SMTP

Actual behaviour

Server error message appears. The message is not sent, just saved as draft.
This is something relatively new, it appeared randomly in the last week or so. Nothing unusual happened, not even an update to server. No other modification in settings was made, I am using unified inbox.
Everything else is working: incoming mails, notifications, saving attachments to Files, etc.

Horde_Mime_Exception: already authenticated

That is … weird.

The Nextcloud mail app offers an extensive logging system to make it easier identifying and tracking down bugs. Please enable debug mode and set the log level to debug in your admin settings. Then, try to reproduce your issue and take another look at data/nextcloud.log, data/horde_imap.log and data/horde_smtp.log.

Hi,

here are the logs:

logs_errors_mail.txt

The problem is now persistent.

[laurentiu2]

For no obvious reason, after deleting the second email address, it works again. After re-enabling the second email address it still works.. Hopefully for a long time :)
If you want to keep investigating, maybe you'll find the problem.. but for me it can be closed.
Thanks.
