Let's go over this again, just FTR. The fact that you are using RFC 1918 addresses on your mail host, and NATting them at the firewall, is totally immaterial. There's no way for these IP addresses to be "announced" to servers on the public Net. They aren't routable. What's material is that you're setting up IMail to use a HELO whose corresponding A record points to an RFC 1918 address. Despite the fact that there's some part of "DNS roundtrip" test you might think you pass, that's at root an *extremely bogus* HELO, and it shouldn't surprise you that remote servers balk at allowing connections from you. the presence of additional private addresses in the zone is also a bad idea, though here if the only information a remote server has tested is the HELO, that's bad enough. --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/
