Summary of the issue you are facing:
Sending mails fails, POST /apps/mail/api/outbox/10 fails with error 500.
The mail server is handled by OVH.
tcpdump ‘port 465’ indicates no message is even sent.
tcpdump ‘port 993’ works well and messages from IMAP are indeed correctly received.
No errors in the logs linked to the mail sending, except:
OCA\Mail\Controller\OutboxController::index uses the @NoAdminRequired annotation and should use the #[OCP\AppFramework\Http\Attribute\NoAdminRequired] attribute instead
dirty table reads: SELECT * FROM `*PREFIX*mail_mailboxes` WHERE (`account_id` = :dcValue1) AND (`name_hash` = :dcValue2)
But those are debug level.
No logs in php logs.
Steps to replicate it (hint: details matter!):
- Install the docker image 30.0.13 + mailapp 5.1.10 configured with postgres
- Configure the mail account for IMAP 993 and SMTP 465
- Try sending a message

Tips for increasing the likelihood of a response
- Use the
preformatted textformatting option in the editor for all log entries and configuration output. - If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
- Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
