I'm afraid you're going to have to get your mind around pushing out a port change to your users. Of the client-side modifications (use ISP's outbound, force VPN first, change SMTP port) it's the easiest to roll out. Ultimately, anything unprotected that accepts unauthenticated mail for your local domain--even if on a non-well-known port--will be vulnerable, but for now the port change offers the best balance of rollout-ability and protection. --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/
