Select Queue

I have made an update to alexlehm’s version of this script to include a -q parameter with which to select which queue on which to alert.

This change arises from an issue we have seen at my company where the postfix server gets flooded with several thousand messages at once. Postfix continues to process them, so they do not get moved to the deferred queue, but the active and incoming queues grow to almost 2GB apiece.

The new version can be downloaded here: https://gist.github.com/mlwood98/c5cb1e80be595b625c60
