A problem with HTML mails and CSS is that they don't render the same
in all mail clients. I have searched a way to convert CSS page into
pure HTML (without CSS) before sending it, but I didn't found any way
to do so. Maybe something like http://wiki.tcl.tk/12383 but for PHP
would make sent mails look better.
