Is it possible to use just the username in mail client instead of full email address?
Question asked by - June 2, 2017 at 12:33 PM
Hi everyone. I'm getting very mixed answers on this question from forum users and SmarterTools so I was hoping to get a clear answer today. I know this is possible in webmail and I know how to make it happen, but I need to know if it is possible to do in a mail client such as Outlook. As you know, certain mail platforms let you set up users with just the first part of their email addresses. For example, IpSwitch's Imail server has you set up users as "user" instead of having to set it up as Because of this, some Imail users have only their username set up in their mail client as the authenticating address instead of their entire email address. When a migration from Imail to SM stakes place, this causes the users to have to go into their mail client and change their username to their full email address. As you can imagine, this is a huge problem when dealing with 1000's of users. Is there a way to allow a user to authenticate with only their username from their mail client to SM? I believe there were one of 2 people in the forums that said they had accomplished this, but didn't explain how to do it. I tried to reach out to those guys with no response as of yet. I'm hoping someone can let me know if it can be done and how to do it if possible. Any insight would be greatly appreciated. Again.. I know this can be done in webmail. That's not what I need to know. I need to know if it can be done in a mail client. Thanks!

I sent you a PM with the step-by-steps on how this can be done in SmarterMail. We had the same problem when we migrated 10 large domains with several thousand users over from IMail, as many of those customers were elderly and not technically savvy enough to reconfigure their mail clients with their full email address and frankly our Customer Support department was already going to be overwhelmed with calls for webmail support as it was. So, to make the migration smoother we assigned a unique IP to each domain and bound the unique IP and unique hostname in IIS & Smartermail and it worked a charm.

Let me know if you need any specific guidance. There is some web.config wizardry I can share too that can help if you were using IMail on the old default port of 3000.
