Monit suddenly sending 18.000 e-mail? Gmail blocking your mx IP & getting all other incoming emails to your Gmail account (as it’s getting forwarded to Gmail) delayed?
Have no fear…
mailq | grep firstname.lastname@example.org | cut -d' ' -f1 | xargs -rn1 postsuper -d
Edit the e-mail address.
Note: mainly a reminder for myself. 😉
