Ok, I have a delimna that I cant't figure out. I have probes oon about 100 lists and there are only five that have givne me problems. I even took the headers off of ones that I know work and put thme on these five. I finally got to go out and probe the membes. Below is my header configuration. The probes goes out fine, but it never deletes the bad addresses. The messages come back asa regular error messages to the postman account, on the others I never see error messages, it just deletes the addresses and notifies me that it did it. * Auto-delete= Yes,Full-Auto,Delay(2),Max(100) * Renewal= 4-monthly,99/05/31,Probe I think that the line below is the culprit. I looked at one of the probes and this is in the header of the probes. The thing is that I can't figure out why just these five lists are choosing to have this in the header and not what is suppossed to be there to complete the probe function. Return-Path: <owner-ALMSOL2-L*BARB**CLEMSON*[log in to unmask]> Any ideas? Any help is appreciated I am at dire straights with this one.
