php mail function

I were wondering why the php mail function is not working on my website. After checking my code, I say myself “maybe is a black list problem”. So I check it, and this is the result:


Where I can report this or to whom?
Is there an estimated time of solution for this problem?

Thaks in advance!

Well, if you want to do something, you could report the false positive to the blacklist maintainers. We’re already working on those.
