Hi, We are having trouble with auto-probe which has taken offence to yahoo.com email addresses, deleting 4000 valid yahoo subscribers over the course of two days. I have had to disable auto-probe on that list, and am worried that I should be disabling it on all lists until we get this figured out. Has anyone else experienced this? We have it set to: Auto-Delete= Yes,Full-Auto,Probe(60) Thanks for your help, --Michael
