The most current concept of 587 is as an _authenticated_ submission port. IMO, if you have the port open, you should be running "AUTH only" on 587 (for any submission, no matter what the destination domain), which will prevent spammers from substantive abuse of the facility. --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.mailmage.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/download/release/ http://www.mailmage.com/products/software/freeutils/ldap2aliases/download/release/ 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/
