The file forwards to a non existing mail user “example” and there is no catchall configured


This error indicates that the qmail file redirects mails to the mail system (with |maildrop /home/username/.spamfolder) but there is no mailuser or catchall configured for this address.

Because this should currently not work and incoming mails are just bounced back you are save to remove the qmail file so mails are correctly rejected in the first place.


Warning: We could migrate this setting automatically to the standard mail system, but it might have minor effects to the current behavior of the mailaddress. You could change the configuration yourself using the uberspace mail commands.
