postfix has become a nightmare…tons of spam being sent out…so would be really great instead of managing postfix to be able to offload that work to an smtp service easier. Read both articles and neither make it very clear how to open up the ports necessary to connect to an outside smtp service for sending mail.

We do not provide an SMTP service by default on our OS images so you’ll need to set up an MTA. If you just need to send emails from a web app or form simply installing postfix to provide a local MTA should do the trick. This can be done from your droplet’s command line with:

sudo apt-get update;
sudo apt-get install postfix;

If you require a more complete mail solution this tutorial will guide you but I recommend reviewing this article first.
