Mail-app sending returns error 500 - but sending actually works

Hi, I’m settung up OwnClowd at the moment, and so far it’s been a blast.

I’m getting a strange error with my Mail-App. I connected my private mail and I am able to send and receive, however the Mail app returns “Error: Request failed with status code 500” when sending an E-Mail. (it is working though!)
I searched for Forum and could only find Topics where the 500 error actually was real and sending was not possible.

:thinking:

Any hints?
Nextcloud 19.0.3

PS: I try to attach logs but “new users can only add 4 links” :face_with_raised_eyebrow:

/edit only happens when sending an E-Mail to my saved Contacts

I see, bla@bla.domain is a link. :sweat_smile:

Bingo. See https://github.com/nextcloud/server/issues/21696

So how do I fix this? I cannot send EMails…

It was fixed and backported.
