Godaddy seems to have broken their php mail() command in December 2016. I am trying to solve the problem myself. It worked until mid December, while I was away on holiday, and I just was informed by my staff no emails come through anymore. No errors, php mail() responds with success.

Godaddy changed something and they have not told me what they changed! Annoying, they do this too much, likely moving to a new host soon as my terms are up.

If I can identify the problem I will post it here for you.

What does still work is the godaddy formmail and gdform functions that are built into your hosting account. These are quite ugly, and cannot be customized and only one email address will work.
