I was trying to follow the instructions found here to set up a catch-all account, but still I get the following message for mails sent to non-existent users:
The error that the other server returned was: 550 550 5.1.1
[email protected]...
User unknown (state 14).
Everything else works, though... /etc/mail/local-host-names and /etc/mail/virtusertable were set up as instructed. Any advice? Thanks!
