    No, let me make it clear.

    The problem is that all my requests to the smarthost's port 25 are
    blocked. So, I try to ssh to another computer, forward the port 25 of
    that SMTP server to port 10025 on my computer, and tell exim to use
    localhost and port 10025 as the smart host; but exim refuses to
    relay the mail through localhost, though it is actually a forwarded
    port.

    Any suggestion?

    Thanks.

    Kumar
