My rule-of-thumb for one-way lists is Auto-Delete= Yes,Full-Auto,Delay(8),Max(3) Delay(n)= #days in mailing period + 1 (weekly => 7+1 = 8) Max(n)= max number of bounces before auto-deletion for weekly mailing, a bouncing address will be deleted in 3 weeks Rule: The longer Delay(n), the smaller Max(n) Probe I usually leave at Probe(10) and don't change it unless the list is over 25,000 subscribers.
