[OT] m$ activesync with cyrus backend

[lartc]

hi all,

an off-topic question, but maybe you can help.

i've got a lot of iphones to deploy and funambol will only sync contacts
(apple has not placed access to calender/notes/tasks in their api).

iphone does support activesync to do wireless sync to an exchange
server.

is there a way to mimic exchange server in the linux environment where i
can keep my cyrus/postfix/amavis install -- is there a linux app that
speaks "exchange"?

cheers
