help!! forwarding rules do not work!

[Guest]

Hello,
i have set a rule so that when i receive from a
certain sender, i have it set to forward to an email
address that is outside the domain. but the rule will not
forward it. it will sometimes work if i use the "run now"
button but never automatically.

what should i do.

the altimate goal is to have message from certain people
auto forward to a moble device's email account.

thanks
jon
