mail

For development, you don't want any e-mail sent to the outside world, but you do want to be able to see all mail your sites or application try to send. Here is a configuration of Postfix to do that.

The trick is to BCC everything to a local user, and discard without error any other sending.

This is based on several guides and Q&As online but well, none of them worked for me, so here's exactly what i did (minus all the missteps).

MailChimp had no answers online

If people send e-mail to a designated e-mail address (such as the lists from address), they should be able to be automatically invited to join the list.

My interpretation of their response: I should make a Drupal module to do that.

Actual response:

Hello Ben!

It's nice to virtually meet you! That's a great question and we’re happy to get it answered for you!
