Hi!

I found a bug in the mail header patch when using UTF-8.

If you have a url that contains custom chars, such as å ä ö, the mail header patch breaks that utf-8 encoding when it puts the path into the mailheader.
You will then have a malformed header (see attached screenshot) and will be picked up by spamdetection softwares as "BAD HEADER".

you can find a screenshot of a mailsource of such an email here:

Fix: 

Make sure to use utf-8 compatible functiosn in the mail header patch
How-To-Repeat: create a rewritten url, either with htaccess in apache or in the rewrite config in lighttpd, with one of the chars å ä ö, or probably any other multibyte char. Make sure to set the header and encodings to utf-8 for that site.

Send a mail using mail();

Do you know that URLs don't have a defined charset? 
So don't use anything except ASCII. If you like, you may contact
