I use this:

mailq | grep -c "^[A-F0-9]"

You can pipe the output of mailq through various other filters such as uniq, sort and wc to get other statistics.

  This is not accurate. When the Postfix queue is empty, then run 'mailq', we will get "Mail queue is empty" which also match "^[0-9A-Z]". And in such a situation it is not accurate.

  A better regex is ^[A-F0-9] which correctly results in 0 when the mail queue is empty. I've edited the answer.
