[Note: I am no Nagios guru - I haven't even got my setup to work yet.
Nor have I ever installed a unix mail server. I just know Perl, that's all]

If I do /usr/bin/mailq, I get:
/var/spool/mqueue is empty
Total requests: 0
Now the check_mailq script first looks for the phrase "mqueue" in a
line. In that line, it looks for either "empty", or a number. If it gets
a number, it checks to see if that number is less than the one it
expects, and sets status details accordingly.
Now, if it doesn't find a line containing "mqueue", it will give
precicely the error you have been getting.

Well, that's because your mailq command is giving out a type of output
that the check command doesn't know how to handle. Are there different
versions of mailq available? I dunno.
You could try this in your perl script (how good is your Perl?):
Find where it says:
if (/mqueue/) {
until:
last;
Replace this all with:
if (/mail queue is empty/) {
$msg = "OK: mailq is empty";
$msg_q = 0;
$state = $ERRORS{'OK'};
last;
}elsif ( /in (\d+) request/ ) {
$msg_q = $1 ;
print "msg_q = $msg_q warn=$opt_w crit=$opt_c\n"
if $verbose;
if ($msg_q < $opt_w) {
$msg = "OK: mailq ($msg_q) is below
threshold ($opt_w/$opt_c)";
$state = $ERRORS{'OK'};
}elsif ($msg_q >= $opt_w && $msg_q < $opt_c) {
$msg = "WARNING: mailq is $msg_q
(threshold w = $opt_w)";
$state = $ERRORS{'WARNING'};
}else {
$msg = "CRITICAL: mailq is $msg_q
(threshold c = $opt_c)";
$state = $ERRORS{'CRITICAL'};
}
last;
}
That _might_ convert your check_mailq script into one that will work
with your mailq command.
I make no promises though.
