Email class - incorrect headers?

Neither do I. The strange this is that if the message is just text, NOT multipart text/html, it comes through our server fine! Yeah, I tried removing...

User-agent
X-Sender

Didn't work.

I then also tried changing $this->newline within _send_data() func. (for SMTP comms.) to $this->crlf (crlf = \r\n) and then keeping newline as \n but that didn't work either.

I also tried changing the format of the boundary. That didn't work. And the I tried changing the charset from utf-8 to iso-... but that didn't work!

It's really got me going to figure out why.
