This evening I uploaded beta-5 of Email Users v4.6.10.  I am trying to add Base64 encoding support which was recently requested in the Support Forum.

I could use some help with this as I cannot get it work and am hoping someone familiar with Base64 encoding can see what I am doing wrong.

I have added a new option on the Settings Page to allow encoding email in Base64 format.  In my test environment, when I enable this, email is never received so I assume it was never sent properly.

The code in question is in the mailusers_send_mail() function which appears in the email-users.php file starting at line 1445.
