What mailer are you using / how is it set up. I did not do the installation, but we are running LMAIL here and if there are ANY header errors, the item goes to POSTMAST and other designated Ids and nowhere else. This includes items with multiple ( even if exact duplicate ) "From:" headers which used to go thru under our previous MAIL handler. Do we have things screwed down unusually tight ?? It DOES seem catch a lot of potential problems before they get into the listserv stream ... - Mike
