I maintain a list on ua1vm called Pmail. I have problems trying to find out where bounced mail is coming from. For example, I have a couple of bounced messages from PSI.COM, yet getting a listing and looking for PSI.COM reveals nothing. Another example error messages from "[log in to unmask]". After talking with their system admin, it turns out that "[log in to unmask]" is the same as "[log in to unmask]". How do you (list owners) attempt to discover where/how/who bounced mail is coming from? I've found that if you use a Unix box and "mail -v [log in to unmask]" you can at least make sure mail is getting to "suspect". Any other hints, words of wisdom, etc? ---------- Each day the world turns over on someone who was just sitting on top of it. ---------- James Ford - Consultant II, Seebeck Computer Center The University of Alabama (in Tuscaloosa, Alabama) [log in to unmask], [log in to unmask] Work (205)348-3968 fax (205)348-3993
