Please go read mailinglists-policies. In particular note: No HTML or RTF e-mail period, end of story, full stop. Your mail client should let you configure it so you can send plain text messages. Make use of this ability or else there are no guarantees that anyone will be able to read your email. The mailing lists are set up to automatically reject email that is sent as text/html. Thus please configure your email client to send plain text (text/plain) email.
