Anti-spam software-When will someone develop it for the Q?

[antispam]

I cannot believe that no one has developed an antispam software for the Q. I'm sick and tired of having to delete 100 junk emails for every legitimate one.
I do not have anti spam on my server. My regular desktop e-mail (Incredimail) handles spam very nicely.
I tried a server based anti spam option and it deleted important e-mails without me knowing it. It is too dangerous. I would gladly pay the extra bandwidth download charges and have it all delivered to the Q only to have an Anti Spam program delete it.
Programmers-Where are you? Please, please develop an antispam program for smartphones.

I beg you!

Thank you
