Guess what. I managed to get only one email, but I do not know if that is breaking something else.

In vbms_class_mail_message.php: function construct_mime_message(), in the $headermap = array I simply commented out the which I noticed was being called again in the function below

function send($testonly = false)

$result = mail($this->to, $this->subject, $this->html, $headers);

You rock MAN!! I'll do some more testing on your system.

don't touch this function, it has nothing to do with it, that deals with the aliases.

welp, that fixed it for me, both POP and IMAP. Everything else seems okay... so far.

Will do some more testing...

Like I said, we need to do some intensive testing, I am not sure if that breaks something else, such as multiple recipients :tired:

try commenting out this as well...

To see if it fixes the double subject issue

I still get an echo on IMAP emails in the subject line

Multiple recipients is working ok

I'll try, although I haven't got that double subject issue.

you'll only notice it on Hotmail...POP email ricipients seem to correct it.

anyway, commenting it out did not hurt. Try it
