Disable EDNS as suggested by Neil. This is a known issue with Windows 2003 DNS, and one that can be found in several places in the IMail Forum archives. There's no reason to change DNS platforms, just get your platform working acting in the most open way possible. I'd also kick out the forwarders, as they're unlikely to be adding anything but complexity. Of course, ensure that your DNS box is not overtaxed by internal AD traffic and can handle doing the recursion itself. --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/
