    ... and immediately I have been able to verify a bunch of
    domains/servers which won't get thru when incoming connection
    has ECN. I tested all of these with Linux running ECN, and
    Solaris 2.6 without ECN. When Solaris got connection, and
    ECN-Linux didn't, domain and its server got listed.

    Amazing share of these troubled destination systems run some
    firewall which thinks it is cool to fuck SMTP protocol.
    (I mean obscuring responses given by the remote system,
     frobbing incoming protocol if some particular detail doesn't
     please the rules it presumes to play with, etc..)

    I am contemplating to periodically turn off the ECN bit to
    let email out, but DaveM has veto there.

    This list is NOT exhaustive of domains with problems, it
    primarily lists only those who are subscribers of linux-kernel,
    and thus accumulated (al lot) more than 1 email with "connection
    timed out" status into vger's queue.
