I would think the easier solution would be to send out an email with complete instructions on how to upgrade the email accounts in the client software BEFORE you make the actual changes on the server end. Then give the clients a week or two to make the actual changes and warn them that if they don't make the changes, they will no longer be able to send of receive any email.
In the process of purchasing an ISP that had been using IMAIL without requiring SMTP AUTH and fully qualified logins we did just that as part of the takeover process. While there were several users who b**ched about receiving the email and having to make the changes, we had an over 97% compliance rate within the first week and only had to hand-hold about 30 users. For the purpose of the hand-holding, we built a canned email that showed, with embedded graphics, where and how to make the changes and included an explanation that there was a 100 percent mandatory compliance requirement if the user wanted to continue to use their email. A copy of the canned email was carboned to the end user's supervisor (or the person responsible for maintaining the users on the appropriate domain) with a note that if the person refused to comply their email would be discontinued without further discussion on the topic. In the end, we had 100% compliance without the loss of a single user. Remember, if the users and clients are going to complain about spam and all of the other issues they complain about on an hourly basis, then they have to be willing to cooperate when we make changes that will help eliminate some of those issues and make their email more secure in the long run. None of us have either the time or the IP addresses to waste any more! Bruce Barnes -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of John N. Ecker II Sent: Saturday, May 11, 2002 15:06 To: [EMAIL PROTECTED] Subject: RE: [IMail Forum] Migrating from real IPs to Virtual Hosts Guy, I agree, and in a perfect world "1000 hours of Free AOL" disks would taste like chocolate! ;) Problem is, I'm inheriting a mess....the joys of consulting! I'm sure most of my client's users were set up years ago and did not configure their email client software to login so fully qualified. So, my question, considering they are set up this way, is will it definitely cause problems or is IMail smart enough to associate the domain name with the username given the information provided? You see what I am getting at, right? Do I bill my client: 8.0 hours of consulting to migrate from Server A to Server B and recovering lots of IPs that they need --- or ---- 8.0 hours of consulting to migrate from Server A to Server B and recovering lots of IPs that they need and 200.0 hours of assisting hundreds of users to update their Outlook settings -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Guy Isabel Sent: Saturday, May 11, 2002 2:33 PM To: [EMAIL PROTECTED] Subject: Re: [IMail Forum] Migrating from real IPs to Virtual Hosts John, The fact that e-mail users must enter their fully-qualified address while logging in takes care of the multiple-domains issue. On top of this, they all should use SMTP AUTH for security reasons. Migrating from dedicated IP domains to virtual domains should not be an issue as long as users log in using their fully-qualified adresses, e.g. [EMAIL PROTECTED] and [EMAIL PROTECTED] In short, users *must* enter their fully-qualified addresses as their login names *and* you should enforce SMTP AUTH for everyone.
