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. – andy Jul 7 '15 at 12:59

    A better regex is ^[A-F0-9] which correctly results in 0 when the mail queue is empty. I've edited the answer. – Ladadadada Oct 6 '15 at 16:26
  • How silly, the last line of the output is the count – Geoffrey Jan 2 '17 at 23:37

either mailq | tail -n 1 or find /var/spool/postfix/deferred -type f | wc -l

both works

    I get "682430 Kbytes in 26472 Requests." for the first one and "23" for the second one. – rob Dec 18 '17 at 13:28

Pipe the ouput to wc, if further refining is required, use grep.
