:-( I think Gennadiy has managed to convince Outlook to work fine over NNTP.
Thunderbird works fine either way.

And why that code makes you doubt that function output formatters are
helpfull? Basically, he just implemented the same idea: formatter, which
has some begin/end string and nested formatter for elements.

Could you be more specific. I don't know where in the code to look. Do you
mean it's possible to change the separator used betwee name-value pairs?
How?
