Did you look for anything in your server's error_log?

the same issue in 1.6. It worked well in 1.5 on the same host.

Just cross check by disabling Send SMTP username and password option..

Answer 1

In my case, I was missing sendmail, which caused this (or a similar) issue.

The fix was of course to install sendmail, which you can do on a Debian/Ubuntu installation with:

apt-get mailutils sendmail-bin

 

Answer 2

I had to add the 'no-reply@....' as a valid email address on my mail server before it would work.
