The file contains multiple lines which are no mailaddresses

id:content-multiline-contains-multiple-non-mailaddr

This error indicates that you have a qmail configuration file with multiple custom lines. For the standard mail system, we can only set up forwards to multiple mailaddresses with or without a mailbox.

Any other configurations, like redirecting mails to multiple maildirs etc. cannot be adapted. You need to check the content of the qmail file and decide how you want to set this up manually.

To do so run cat ~/.qmail-example with the proper path. Any comment lines starting with # are ignored for this check.

Error

Fatal Error: This configuration is not working with the standard mail system and we are not able to migrate it. You need to fix it or find a workaround using the uberspace mail commands.
