The reason can be that you configured the other email clients
differently, or that Sylpheed's default settings are somehow not
compatible with your ISP.

The message is not generated by Sylpheed, but by the MTA you're
submitting to. This MTA uses SPF (Sender Policy Framework) and
obviously didn't like something about the message "sender".

To see what's awry we would need to have more information, like the
configuration of the clients and the full error message received from
the server.
