We've seen this since 1.8e was installed. Has anyone else seen it? Bounce message comes back to the owner-listname address. Instead of forwarding to the list owner, the message is sent back out to the list address with two "From" headers -- one from the postmaster at the site with the bad address and one from the original author of the message. Since that one is second, the "postmaster" address is ignored and the message goes out to the list. We've been able to block the behavior with a content filter -- but that's a tad annoying. It seems to only affect bounce messages that come in a multipart MIME envelope with the original message included as type "message/rfc822". -- DCP -- Douglas Palmer | Voice: 718-260-2291 Fax: 718-260-2338 SystemsManager, USDC-EDNY | cc:Mail: cc What? 225 Cadman Plaza East | Internet: [log in to unmask] Brooklyn, New York 11201 | CCNA,CCNP perl -e 'print $i=pack(h32,"a455443595350214e6f6e697d6f65737"),"\n";'
