Hi Goswami, Sorry, but you keep asking questions I think I know the answer to!! vbg > For example mails coming for [EMAIL PROTECTED] should go to 'xyx' mailbox Just a little clarification of terms, "user" is the mailbox, and "xyz.foo.com" is the mail domain. [EMAIL PROTECTED] In yr DNS: xyz.foo.com IN MX 1 imail.goswamy.com abc.foo.com IN MX 1 imail.goswamy.com This will get the mail coming from Internet smtp servers into abc and xyz sent to your Imail server. In the NT machine of imail.goswamy.com, in NT "hosts" file, 1.2.3.1 xyz.foo.com 1.2.3.2 abc.foo.com It doesn't matter what addresses are as long as you have them in the following acceptable subnets. Imail will try dumbly to deliver to .1 and .2 hosts, but will be offline. In NT's ControlPanel:Imail:SMTPSecurity:RelayFor(GroupsOf)Addresses: will contain 1.2.3.0 subnet 255.255.255.0 or whatever your subnet situation is. When the Linux boxes connect to your ISP, they will ETRN the Imail server. Since they are seen as coming from a subnet acceptable to Imail, Imail will have a) stored their incoming mail (activated by hosts file) and b) will deliver it when ETRNed from the acceptable subnet (acceptable by SMTP security). This is totally theoretical. Somebody who's done it needs to confirm. The above is the minimum for internet mail store/fowarded by Imail to remote smtp servers. An option you have is whether the remote smtp servers should try to deliver their mail directly to the destination smtp servers or forward/relay all mail through your Imail machine. The latter option is certainly faster and therefore recommendable (but not necessary). It will be an extra burden on your Imail machine.
