@stefanoco @francescor Does this only affect Invitation emails or also other emails from Nextcloud?
georgehrke
on 1 Jul 2020
We haven't touched the actual Invitation Sending code in 5 months, so that can't be it:
https://github.com/nextcloud/server/blob/stable18/apps/dav/lib/CalDAV/Schedule/IMipPlugin.php

Seems like only invitaions emails are affected; any suggestion about what to check? Maybe somehow the template was corrupted during the upgrade process

Are you using custom email templates?
georgehrke
on 1 Jul 2020
No we're not using custom templates

...realized now that:
- this is not happening always: same conditions, same sequence (as listed above), sometimes it happens some other times the message is ok
- the same applies also to email messages notifying folders activities (and again, only sometimes)
Any suggestion on how to debug? Easy way for saving all generated email messages in a log for later inspection?

Further confirmation: creating / deleting the same invitation email from a calendar multiple times the message gets corrupted around 1 out of 4 times. Any debug options?

I am facing the same issue, if anyone have suggestions it will be really appreciated

I'm closing this issue because I realized later that the problem lies in the firewall anti-spam: the anti-spam function adds headers to all email messages, and the messages coming from Nextcloud get corrupted in the process.
Now I'm not sure if this is due to some mis-formatting of email from Nextcloud but I tend to exclude as examining the sources gives no hint.
