Due to a server side misconfiguration, outgoing mails were bouncing for sometime. I identified the culprit to be:

/etc/hosts:

::1			localhost localhost.my.domain

After I fixed it, there was more collateral damage. A large number of subscribers were marked as “nomail” (i.e. delivery disabled due to excessive bounces). I didn’t see an easy way of mass enabling the delivery. So I wrote this little script.

Enjoy.
