email: the recipient was rejected by the server

paid user, connected us1,us2,uk1- so far is fine.

On WinXp SP3 laptop, send/receive email by Thunderbird 3 .1.6 is also fine
On iphone 3GS 4.1, connection works. but when i send email, even to,
“Cannot send mail, a copy has been placed in your outbook, The recipient “” was rejected by the server”

  1. Thanks!
  2. when i restart my iphone, it works now.
