64.7.207.173's published hostname (i.e. its PTR record) is www.ltcconnection.com. Yet www.ltcconnection.com has a published A record pointing to 64.7.202.212. These two factors are out of sync and will cause delivery failures even without the EHLO taken into consideration. Feel like a broken record here... but an outbound mailserver must pass the HELO-PTR-A-IP "roundtrip" test to encourage delivery to even the strictest remote servers. HELO/EHLO matches source IP's PTR hostname. IP's PTR hostname has corresponding A record which resolves to source IP. There are known issues with IMail and other virtual hosting mail suites that make resolving this problem impossible without either upgrading the suite or "multiplexing" all outbound mail through a gateway MTA (which can run on the same machine as IMail). --Sandy ------------------------------------ Sanford Whiteman, Chief Technologist Broadleaf Systems, a division of Cypress Integrated Systems, Inc. e-mail: [EMAIL PROTECTED] SpamAssassin plugs into Declude! http://www.imprimia.com/products/software/freeutils/SPAMC32/download/release/ Defuse Dictionary Attacks: Turn Exchange or IMail mailboxes into IMail Aliases! http://www.imprimia.com/products/software/freeutils/exchange2aliases/download/release/ http://www.imprimia.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/
