What is the best way to handle importing mail users from an outside vendor? We use fusemail right now but are wanting to bring in our 2000 plus email accounts. The problem is we do not have the password for these users. I was thinking if there is a way to set a null password and then when the user logs in the first time it sets the password to what ever the user enters. This would work for 99.9% of the users as most users have their passwords saved. There might be one or two users that call in and can not log in to their email and at which point we can simply reset it. Unless there is a better way please tell me. Not even sure how I would setup my way.
