Hi there,

I am planning to migrate some users to a new iRedMail server from an old Qmail server. I have all of the passwords for the users, and would like to keep the same passwords to avoid a user revolt.

FIRST:

I have seen the script at tools/create_mail_user_SQL.sh. Before I try and hack it myself, has anyone come up with a script to create a SQL output file that contains individual passwords instead of a single default password? In other words, if I start with a flat file containing user names, domains and passwords, does anyone have a script that can run through that list and create the necessary SQL output file based on the existing user names, domains and passwords?

SECOND:

It has been a while since I've done a mail migration, but once I've created the users on the new iRedMail server, I'll probably use an old IMAP-based migration tool I've used before. Has anybody done this and, if so, any tips or pitfalls to consider?

THIRD:

I've read the features and comparison list, but I'm confused about the difference between a "global admin" and a "normal admin". Ideally I would like to have different admins for different groups of domains -- e.g., admin1 only manages domain1, admin2 manages domain2 and domain3, admin3 manages domain4, domain5 and domain6, etc. Is this possible? Are these sub-admins "normal admins", and does the "global admin" manage all admins and all domains?

And can I initially set up the open source version of iRedMail with all of the domains, then upgrade, then assign each domain to the appropriate "normal admin"? Or must I start with a pro version from the beginning?

Thanks in advance for answers to these questions.
