P.S. What's up with the literal quotes in your display-name? Is that my mail program acting funny, or yours?
My mail program puts
=?ISO-8859-1?Q?=22Martin_v=2E_L=F6wis=22?= <martin@v.loewis.de>
into From; this decodes to
"Martin v. Löwis"
So two of the quotes are mine (from thunderbird) - the other two must, and the backslashes, must be yours.
Regards, Martin
