Fortunately MX records and by extension SPF info per domain changes infrequently enough that a semi-manually maintained list will be mostly right, most of the time. But you're right in principle -- I *should* really take the time out to recreate the list of domains that went into it and just re-generate with smtpctl spf walk something like once per day or once per week. All the best, Peter I regenerate once an hour at least and still get burned by some major domains changing SPF IP's constantly. It's pretty frustrating, but once you get an update process in place it settles down and doesn't require much handholding. Thanks Scott
