Yep, you're right. =:\ I thought it was going to be a simple question
about the unless statement. Turns out I was headed down the wrong path, so I
changed the variable name to make it clear. Next time I'll keep that in mind.
Also, I adopted your use of my $host = $mail_field || 'localhost';
Nice and concise!
my $mail_field = 'mail.example.com ';
$mail_field =~ s/\s+//g if (defined $mail_field);
my $host = $mail_field || 'localhost';
Thanks again,
Marc
