It depends on how you set up your probe configuration. With active probing set an actual probe message will be delivered to the email address LISTSERV is questioning. With hands-free bounce processing (passive probing) the email posted to the list will act as the probe message. -----Original Message----- From: Tim Parker [mailto:[log in to unmask]] Sent: Monday, April 16, 2001 2:51 PM To: [log in to unmask] Subject: Re: Probe percentage Side question off of this one. Is the probe a part of the "daily or weekly" mailings or is it a seperate mailing? I have received probes from other lists and want to make sure ours is not sending out extras if I add this on to our lists. Sorry for jumping in here, but it is something I am interested in learning.

Changing the value for Probe(n) in the Auto-Delete= line is the only way to change it. The value of n is commonly though of as 'days'. However this only applies if your list mails out every day. What n really represents is the denominator of a fraction of the list to be probed. (The numerator is always 1.) If n=10 then 1/n=1/10 (or 10%) of your list will be included in the passive probe at the next days mailing. If you mail every day for 10 days, then the entire list will have been probed (unless the subscriber list also changes substantially during that time). If you only mail once per week however, it will take 10 weeks to probe the entire list at 10% each time. Since n is the denominator, higher values of n will result in smaller fractions of the list being probed. e.g. n=20 then 1/n=1/20 or 5%.
