>>The "Sender:" field is where well-behaved mailers send bounces. > >Well-behaved mailers send bounces to the SMTP envelope from address >(MAIL FROM:). IMHO, Well-behaved mailers send bounces to (in order) a) the List owner address (errors-to: ?) if the mail came from a MLM. b) the Resent-From: address if the mail was forwarded. c) the Sender: address if present and not a MLM. d) the From: address if none of the above qualify. ----------------------------------------------------- Chris Barnes | President - Bryan/College Station [log in to unmask] | Retriever Club (409) 846-3273 (home) | "Dedicated to the betterment of (409) 845-8300 (work) | the retrieving breeds"
