It would appear to me that the [log in to unmask] is using the RFC822 ERRORS-TO: field embedded in the message to bounce the message. I'll bet there will some debate if that is correct. I suggest that you DELETE those subscribers that are no longer valid, and SET NOMAIL (or possibly DELETE) those that have full mailboxes. -- co-owner: INFOSYS, TQM-L, CPARK-L, ERAPPA-L, JANITORS, LDBASE-L, et -L URL:mailto:[log in to unmask] "I get paid by the millisecond"
