> Add a lowest priority MX record for the customer domain Bad design.
Why bad design ?... It works very fine with many customers on mine. To clarify here is the scenario. DNS declarations on my DNS server on same server where I have iMail server @ MX 10 mail.company.com. @ MX 50 office.company.com. mail A 123.123.123.183 <- my iMail Server office A 234.234.234.123 <- Customer's Exchange Server rules.ima for each account of company.com S~[SPAM!]:[EMAIL PROTECTED] S~[SPAM]:[EMAIL PROTECTED] S~[SPAM?]:[EMAIL PROTECTED] F~@:[EMAIL PROTECTED] Alberto [a] MX records should not be published for hosts that are known to be unreachable from the public Net; [b] you don't need to use DNS RRs for routing, only HOSTS. Might want to take a look at my age-old exchange2aliases script, which is designed for this scenario. As far as delivery, yes, this is as fast as an extra SMTP hop can be. There is no push/polling latency, just the scanning latency. --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/downloa d/release/ http://www.imprimia.com/products/software/freeutils/ldap2aliases/download/re lease/ 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/ 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/
