  1. [9fans] problems sending mail to plan 9 systems

    it seems I (our site?) can no longer get e-mail across
    to (certain) plan 9 systems.
    e.g., to the system handling the inferno mailing list.

    could there be a clash between plan 9 anti-spam
    measures and the greylisting used at our site?

    it seems the message doesn't get delivered due
    to 'deferred: smtp ping: smtp: interrupted'.

    I copy/paste below (slightly edited) most of
    the message our local mail daemon sent me.

    Axel.
