Setting permissions like that is rarely a good idea. 777 means readable,
writable, and executable. You only need something like 644 for aliases,
because you run newaliases as root anyway. 777 may, in some cases, cause
programs NOT to work due to security checks (file permissions wrong)...

Yes you're right you might need a comma there.

Now, if the aliases are correct, and you have run newaliases, and mail
is still going to the catchall, then you'll have to show an extract of
your aliases file, the email address you are sending to, and the
delivery success in the mail log for any further troubleshooting.
