NethServer Version: NethServer release 7.6.1810 (final)
A server I’m responsible for used to be able to use Roundcube / Filter to do a Vacation notice.
Now it seems the same rules don’t work.
Even a simple “Refuse mail with error message” seems to work, no new mail turning up, but no error message is being sent either.
It seems the filter can’t send anything anymore. No error messages to be seen, either in mail or roundcube logs (At least those shown in the WebInterface).
Removed Roundcube (And with that my mail!) and reinstalled it after a reboot.
Still not working, and no errors shown.
