But for just a policy to restrict mail to/from the internet for certain users would there be any better solution? This is just the way it's always been done here.

Well, that's the case with any domain without an MX record. It has nothing to do with whether it's IP-ful or IP-less, or private-IP-ful or public-IP-ful, within IMail. And, of course, a determined person could send mail to that domain by hard-coding the mailroute. I think you're doing the right thing by making a domain that would require malicious/anti-policy intent to receive mail from the Internet, but there's nothing _technically_ totally segregating it from the outside world. --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/ --- This E-mail came from the Declude.JunkMail mailing list.
