[escribana]

Seems like this bug rises its ugly head again?

BTW: My contact groups have names with spaces. Is this forbidden?

[damixem]

I have the same problem !
When I send a mail with 5 or more recipient, I have the error 500

[escribana]

I have some more information about this fatal error.
As you can see in the the following screenshot of the browser debugger the resolution of a contactgroup (called "Test") does not take place!! Sending the message to "contacts:test" results in HTTP error 500 of course.

[LostinSpacetime]

I believe I have the same problem with a slight difference in the error log:

[ChristophWurst]

Expanding group recipients to memeber recipients is missing in the outbox implementation.

[escribana]

@ChristophWurst: Many, many thanks for the fast reaction: I will do some more tests, but group mails are working again so far!

[LostinSpacetime]

@escribana What did you do to apply the patch? We are using the mail app in our school and, as it is, teachers can't write to the parents groups right now. So, it's quite urgent to fix this, and I don't have any experience with GitHub. Can you please help?

[ChristophWurst]

https://docs.nextcloud.com/server/latest/admin_manual/issues/applying_patch.html should help. https://patch-diff.githubusercontent.com/raw/nextcloud/mail/pull/6460.patch is the patch.

[LostinSpacetime]

Thank you, @ChristophWurst, I applied the patch and sending mails to groups is working. However, some email servers (GMX, web.de) didn't accept the mails, which didn't happen before. I get this error:

Remote host said: 554-Transaction failed
554-Reject due to policy restrictions.

Sending emails to the same recipients works if I don't use the group. Maybe the email headers are not syntactically correct.
