If i encode mail string with :
http://www.neokraft.net/sottises/mailencoder/

mailto:[e-mail]?subject=subscribe%20test became : 
mailto:%73%79%6d%70%61%40%74%6f%74%6f%2e%6f%72%67%3f%73%75%62%6a%65%63%74%3d%73%75%62%73%63%72%69%62%65%25%32%30%74%65%73%74

This could be used to defeat spam robot.

but mozilla open the mailer with :
[e-mail]?subject=subscribe%20test
as e-mail adress instead of filling the subject fields.

The '?' char separates the mail address from the fields.  But if it's encoded,
it loses its special meaning, like all special chars in urls.  Otherwise, how
could you put a '?' into the address?

So our behavior is correct.  In the same way, if you escape:

http://foo.com/bar

the '/' after foo.com loses its special meaning and the hostname becomes
"foo.com/bar".

The only bug I see here is in the software that blindly escapes every single
char in the URL.

ok, i understand the behavior of special character : "?"  and "=" but why "subject" can't 
be also hexa encoded ?
