Locked mail box (409) by Signed mail certificate ?

[Aveyron-RetD]

Steps to reproduce

1. I have twice received an email signed with a certificate from a new contact. Both time my mailbox locked.
2. First my mailbox locked and i could not access it
3. I deleted my mailbox and re-added a new mailbox
4. Obtained for the first time a signed mail (This certificate is not)
5. Replied to the guy
6. My mailbox is locked again today
7. I have a pending email on the server from the same contact.

I believe this is not a coincidence.

mail: Background sync failed: undefined
Object { app: "mail", uid: "", level: 2, error: MailboxLockedError }

app: "mail"
error: MailboxLockedError: undefined

I have moved the suspected mail which triggers the fault into a folder on the mailbox from the server => the mailbox is working now.

Thanks for the report! The mailbox will automatically unlock after a synchronization, unless the synchronization crashes hard.

Please check your nextcloud.log and php error log. There is most likely an error before. Please post the details of that error.
