I posted the original message in this thread. What I am looking for is notification when a subscriber does not receive a message (permanent error). We need to investigate each case since this a distribution list and it is critical that all parties receive the announcements. What I am trying to avoid are messages short of a complete delivery failure to cut down on work load. Does Listserv attempt to resend a message if it gets an initial failure? -----Original Message----- From: LISTSERV list owners' forum [mailto:[log in to unmask]]On Behalf Of John Lyon Sent: Tuesday, September 14, 2004 16:46 To: [log in to unmask] Subject: Re: Auto-Delete > What exactly is meant by "monitored".

Correct, providing the two bounces are permanent and are in a format that LISTSERV can understand. Passive probing really has nothing to do with this except you may be more likely to get a bounce with Probing than without. Probing is for those mailers which bounce messages in a non- standard format. With a probe bounce, LISTSERV can determine the list and subscriber address when it could not otherwise. > In other words, given the > below example, if the list only goes out once every 30 days, bad addresses > will not be unsubscribed correct? > > Auto-Delete= Yes,Semi-Auto,Delay(20),Max(2),Probe(0) Correct. That is why using the proper settings for the posting habits of a particular list is so important. If not setup correctly, either the Auto-Delete feature will not work at all, or subscribers are not given a proper chance if there ISP had temporary difficulties. With a list that only posts once per month, you would probably want to use something like: Auto-Delete= Yes,Semi-Auto,Delay(92),Max(3) This will afford them 3 bounces before being snuffed. In your original example, I assumed 3 messages posted per month split over maybe every 10 days. Of course you might post 3 messages on the 27, 28 and 29th of each month. Then of course you would want to use this: Auto-Delete= Yes,Semi-Auto,Delay(31),Max(2 or 3),Probe(5) Again, you must know and set this for the posting habits of the list for it to work as you need/want. > -----Original Message----- > From: LISTSERV list owners' forum [mailto:[log in to unmask]] > On Behalf Of John Lyon Sent: Friday, September 10, 2004 10:14 PM To: > [log in to unmask] Subject: Re: Auto-Delete > > > I am looking for some suggestions on the setting for this keyword.
