We are currently running MS Exchange 5.5 on Windows NT 4. We host email for approx. 1100 customers (including our in-house people). For most of our customers, we also host their "virtual domain" website. So, in addition to our own domains we host about 200 domains worth of email.
I am trying to do a migration from Exchange to Imail 7.06 (Windows 2000 Server). I have found that the structure is very different between the two. In Exchange, I can just add a user to the NT User Database which attaches to a recipient account in Exchange. Once the recipient account is created, I can add as many email addresses as I want to under the recipient account. I can cross over domains because the domain routing list is separate from the user list. For example I can create an NT User account called "User1". This creates a recipient called User1 in Exchange. I can then add email addresses under User1's account so that any emails sent to [EMAIL PROTECTED] as well as [EMAIL PROTECTED] "funnel" into User1's account. User1 then sets up his email client software to access only one account but receives mail for two email addresses. Apparently in Imail, in order to accomplish this, I would have to decide which email address to make the primary recipient (in our case, let's make it [EMAIL PROTECTED]). I would have to set up a user called "User1" under a host called "mail.domain1.com". Then I would have to set up an additional user called "User1" under a new host called "mail.domain2.com" and have it forward all mail to [EMAIL PROTECTED] Is this the only way to do it? Is there a better way? Another big problem I forsee with migrating to IMail is that all of our customers currently have their client software set to access one domain (example) mail.domain1.com as their POP3 server. From what I understand, a user can only access his/her mail by setting the POP3 server for whichever domain their email address is under. Example, if my email address is [EMAIL PROTECTED], I have to check mail.domain2.com and [EMAIL PROTECTED] has to check mail.domain3.com. This will create tons of additional work for me because I'll have to contact every company that has a virtual domain with us (over 200) and have them change their POP3 setting. If I'm way off base here, please correct me. If anyone out there has migrated from Exchange 5.5 to Imail, I would be extremely grateful if you could provide some insight on how you made the move. In a perfect world, I'd like to have as little downtime as possible while making the move. I'd also like to be able to not make everyone have to change their pop3 server setting or account name. I'm not quite as concerned about the forwarding thing, but am obviously open to suggestion if I'm not understanding that concept. Thanks in advance. ======================= Scott M.
