A recent botnet attack on a site I manage createded a massive amount of emails in the mail queue.

Before the email system was brought back up, I had to clear them from the queue.

The following little bash script does the trick.

QIDS="$(mailq | grep -B1 'emaildomaintowipe.com' | awk  '{print $1}' |grep -v emaildomaintowipe|grep -v '-')"
for q in $QIDS
  postsuper -d $q
