Debian 11
Apache2 behind nginx reverse proxy
Nextcloud 25.0.3
Mail 2.2.4
PHP 7.4
mariadb
I have just completed setting up Nextcloud and noticed that all the emails are being cut off at the bottom. I have noticed a few people complaining about this in GITHUB and I did leave a response there. It looks like the maximum lines in the email body are somehow capped at about 5.5? Then everything else is cut off.
Anyone else having this issue? Would an upgrade to Nextcloud 25.0.4 fix this?
Making a bit of progress here — Update.
I logged into the Nextcloud server (remove desktop) and logged into nextcloud on localhost instead of the https//my.example.com and everything displays correctly. So, There has to be something preventing things from displaying. Im not an expert but I think its connected to https versus http ???
FIXED. 
I needed to add ‘overwriteprotocol’ => ‘https’,
To the config.php file. Restarted Apache to be sure. Current recieved emails I did not see a change but any new ones coming in are now displayed correctly.
Hopefully this will help anyone else having this issue in the future
