  1. We have just added a new spam-blocking feature called greylisting to our mailgates. When enabled, greylisting delays messages from unseen e-mail addresses for a short time (configured to 30 minutes right now). Messages from addresses that have been seen before are allowed through immediately.

    Is the "seen" list initially populated from our whitelist, or do we have to experience the delay once for every one of those, too?

  2. It's working again. Looks like it was only out for a couple of hours, if that.

    OK, this is back intermittently. It only happens at work, so may be a firewall issue (though the error message leads me to believe the connection was established but failed to authenticate, it does take about as long as a failed TCP connection attempt so maybe that's what's really going on).

    I see one A record for smtp.cesmail.net from dig. Is that a round-robin?

    It would be helpful to have a list of all the IPs used for that name so we can enable them all in our outbound firewall rules.
