You'e talking about creating internal mailroutes that differ from public DNS records. There are at least three ways to do this using IMail alone; there is no need to introduce third-party mail software. 1. Use the Windows HOSTS file. The format is 1.1.1.1 domain.com where domain.com is the domain you want to route to the host at IP address 1.1.1.1. The advantage of this method is that it is very easy to configure. The disadvantages are that (a) it affects all name resolution from the IMail box, not just SMTP-related resolution, and (b) it does not support multiple MXs per domain, nor MX priorities. 2. Create internal-only versions of your external zones on the recursive DNS servers already used by your internal workstations and servers. The advantage of this method is that it offers full multiple MX and MX priority support. The disadvantages are that (a) as this affects _all_ name resolution through those servers, the zone files need to be fully maintained, including DNS records both in and out of the mail realm, and (b) if you don't have an entire zone available for translation/replication, or it is in constant flux outside of your workflow, using this method will be impossible. This method may be the one you already "frigged" (quite risqu� in US English, by the way!). 3. Run a local DNS server on the IMail box that is specifically for use by IMail. The advantages of this method are that (a) you need only create the MX-related resource records in each zone, as this server will not be consulted by any other services, servers, or workstations, making it flexible and easy to maintain, and (b) you can use DNS' built-in replication to "syndicate" the data to other mail servers in your network if necessary (not necessary if your remote sites always use you as a smarthost). This is the method I'd recommend you go with. --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 Addresses into IMail Aliases! http://www.mailmage.com/products/software/freeutils/exchange2aliases/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/
