Email class bug - HTML problem [SOLVED]

[eluser]dootzky[/eluser]
Alright guys, just to hit you back - it's WORKING!!

Almost every client is working for me, the only problem now that I have is with "Yahoo" emails, because there the email doesn't show up at all. I mean - I do get an email from my server, but I see the blank page.

Do you have any more tips for me?
I've read on the web that many developers and many bigger companies are having problems with Yahoo lately, so should I keep digging for solution, or just accept the fact that I cannot push HTML emails to my Yahoo users?

thanks again for the time,
cheers,
dootzky
