mail using outlook.this connection is 64k.when using skype the connection is on and off.

CCQ is not that good. What is the distance on this link?

On outlook, if you can receive and can't send, it is because the smtp email server set in outlook will not relay email for the public address of your router.

the distance is about 2km apart.i have a clear line of sight very clear.

Then very clear to say it's the polarization issue if it within the coverage.
