Depends upon how many digests are "cut" per period in question. Also depends upon how agressive the mailer is in notifying you e.g., unable to deliver for x days, will continue for y days where typically every x days you get another notification. I think I've seen this annoying behaviour via PMDF. /Pete Weiss at Penn State
