The file contains an internal redirect to a mailuser

id:content-linuxuser-mailuser

This error indicates, that you have set up an internal redirect to a mailuser without a full mailaddress. We can only support full mailaddresses as forwards in the standard mail system.

You should set an explicit mailaddress here. Otherwise we will create a forward to the default mail domain mailuser@username.uber.space.

Note

The current setting does not use the spamfilter but it will be enabled in the new mail setup.

Warning

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.
