"Use" the secondary, if it's the only MX record IMail ever sees = perfectly valid for IMail, broken in DNS. "Use" the secondary, even if the primary MX record was returned to IMail = broken for Imail, valid for DNS. > The problem when it does resolve to their 2 MX record, is that server does > not except email. i.e., their server is broken, and they're showing it off. > Our caching in Imail has been turned off for years.

The cache should contain all MX records that were originally returned.

It must pull all valid MXes -- how else would it be able to retry? --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/ --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
