/var/spool/mqueue is the file where your spooled mail is held. It's not 
the mailq program. For some reason, your mailq app is outputting 
something different from mine (and from that of the check_mailq 
developer). So you have two choices:
1) Get hold of a different mailq command
2) Update your check_mailq script (as I described) to work with your 
mailq command.

What OS are you using?
