Thanks, Michael. I thought I remembered all of the 888 subscribers :-) but I did find a kerstein at another server. It was a general scan and I did not find another one. The subscription shows it is a mail account and I sent a message to check it and it has not returned. However, the bounces are not instantaneous as the one I sent already was originally posted at 2 PM this afternoon and had just been bounced by knology.net and received by me shortly before I sent it to the list. I am hoping it will bounce and that I will have found the missing link. I will wait to write the subscriber until I know for sure. I will let you know. Thanks to all.

Chances are this subscriber is forwarding mail from an entirely different address to the knology.net address. >Sometimes I see earthlink in the header but with the same bouncee. > Similarly, did you try 'SCAN FLORIDABIRDS-L earthlink' (as above) to see if some obvious pattern pops up? If it *is* a situation where a subscriber's forwarding to another address then the probe methods that Pete Weiss suggested earlier may be the only way you'll discover the culprit. His suggestion of sending a DISTRIBUTE job would yield good (and faster) results, too. However, as Pete's already pointed out, this would require contacting the LISTSERV Administrator for assistance. -- Regards, Michael Shannon Senior Consultant, Asia Pacific Region [log in to unmask] L-Soft international, Inc. http://www.lsoft.com Chazzozz!!
