If it's working then I'd say yes. What I'd do is open up the .pm file in vi/emacs/pico and look at the line in question. If you see something like the following, it just means that it's trying mailhost first and it's failing.

    unless(defined($host)) {
        local $SIG{__DIE__};
        my @hosts = qw(mailhost localhost);
        unshift(@hosts, split(/:/, $ENV{SMTPHOSTS})) if(defined $ENV{S
+MTPHOSTS});
        
        foreach $host (@hosts) {
            $smtp = eval { Net::SMTP->new($host, @hello) };
            last if(defined $smtp);
        }
    }

If you are the sysadmin, you could just remove the mailhost out of the qw() or set up the alias for mailhost in /etc/hosts. Another way to supress the warning would be to specify loclhost in $ENV{SMTPHOSTS}.
