Please help, why can I send mail to yahoo?
This is the message which I received:
This message was created automatically by mail delivery software.
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:

SMTP error from remote mail server after initial connection:
