Couple days ago my server got blacklisted. All of my users can not send any email and there’s more than 100 email bulking on my server.
After checking queue with
postqueue -p
There is 100 email sent from marksonventures@hotmail.com which I know it was not my user.
Then use this to delete them
mailq | tail -n +2 | grep -v ‘^ *(‘ | gawk ‘BEGIN {RS = “”} /marksonventures@hotmail.com/ {print $1}’ | tr -d ‘*!’ | sudo postsuper -d –
Done π
