Help Needed - HTML for Email on Lotus Mail

Hello Sir,

I'm a designer and am into HTML coding too. I am having severe problem in 
writing good mark-up for Lotus mail. When the html mailers that I design 
is received by people who view their mails on Lotus, the formatting goes 
hay wire.


Are there any places on the net  where I can get some teaching resources 
on this specific issue.

Would await your reply eagerly.

Regards,
Avinash
