Intoduction and a first question

[PJ]

Hello,

first of all i want to introduce myself:
My name is Peter Jänicke and i live in Erlangen/Germany.
I am an hardware engineer and write software in my spare time.
Since i am using KDE for several years now (starting with KDE 2.01), i felt 
that it is now the time to start contributing.

And here is my first question:
Several month ago, when i browsed through the archive of the kde-core-devel 
mailing list, i read a discussion about a "password strength meter" for 
KPasswordDialog.
Only a few weeks before this discussion, i had worked on an algorithm for such 
a calculation.
Since i think the code which is now used in KPasswordDialog has some 
sortcomings, which my code doesn't have, i wrote a mail with a patch.
Because i don't have write access to the kde-core-devel mailing list, i send 
the mail direct to the developer, using the mailaddress form to sourecode.

But I got no responce at all, which i not very motivating when you just tried 
to do your first contribution. 
Could this be because of some (spam-)filtering or something similar?
What would be the right way to convince the developer to take a look at the 
code?
