However note (from 6. Protocol Flowchart) that an expected server configuration option is "Do I accept mail from non-DMP site?" To quote from that same section: When a non-participating client connects to a participating server, it SHOULD respond as though the Protocol didn't exist. However, as the Protocol gains acceptance, it MAY respond as its operators wish. For instance, the server MAY refuse e-mail until the senders participate in the Protocol, or accept the message and include additional headers in the message to inform the recipient. My guess would be after a while you'll start to see admins flip the switch to say "550 ERROR Need DMP Records". -- [EMAIL PROTECTED] "The avalanche has already started, it is too Rod Dorman late for the pebbles to vote." � Ambassador Kosh To Unsubscribe: http://www.ipswitch.com/support/mailing-lists.html List Archive: http://www.mail-archive.com/imail_forum%40list.ipswitch.com/ Knowledge Base/FAQ: http://www.ipswitch.com/support/IMail/
