Mailing list mirroring broken
Looks like mailing list mirroring has been broken since the beginning of January:  
first broken post: http://www.freelists.org/post/nim-dev/Nim-threads-vs-Pthreads

Looks like it does not allow html posts anymore?
Maybe there's an option to set on the mailing list: http://www.freelists.org/wiki/faq/enable_html
Or we should just send plain rst (without converting to html).
