[Nagiosplug-help] Duplicate specification with check_mailq

[Clif J. Smith]

I receive the following error when I run check_mailq:
# ./check_mailq -w 10 -c 20 -W 10 -C 20
Duplicate specification "Warning=i" for option "warning"
Duplicate specification "Critical=i" for option "critical"
OK: mailq is empty|unsent=0;10;20;0

I've tried versions, 1.4.0alpha1 and HEAD-200410061647.

Please help, Clif
