I have migrated mailbox from my old server to new server via imap. There are some very handy imaptools to do this for you:

Will you share more details about your migration?
I think it will help more users

There are other things like how to move unread mailmessages from the old mailserver (SAMBAR Server 6.4 => out of lifetime [running on W2K-Server]) in mbox-format to iRedMail ?

iRedMail uses maildir format, you have to migrate mbox to maildir first, and then copy them to new mailbox.
Search 'convert mbox messagees to maildir format' in Google will help you.

Example to create a maildir format mailbox:

# mkdir -p /path/to/new/Maildir/{tmp,cur,new}

You can copy unread mails to 'Maildir/new/'.

Send a welcome mail is another way, choose the one you preferred.

Good luck.

How to create the directory-tree by default to copy unread messages in it -> ?? sending each user a wellcome mail ??

By default -> default_pass_scheme = CRYPT
Passwords were stored as MD5-CRYPT hash in vmail.mailbox table  e.g. --> $1$eefCcAhm$sSwG4cgC5GBMpzgEvfuqP0

What I need is PLAN-MD5.
Password like --> d512598b6df069f39381c3db78aaecdb

I´ll change Dovecots default_pass_scheme to default_pass_scheme = PLAIN-MD5 and Postfixadmin to $CONF['encrypt'] = 'md5' instead of $CONF['encrypt'] = 'md5crypt'

Hope to be able to post my success!
[ iRedMail = success ]

Insert MD5 hashed password into SQL, it should work as expected.
Password of user created in PostfixAdmin is MD5 hashed by default, no addition modification required.

Set value to 'ALL' in 'domain' column of vmail.domain_admins table, That's it.

2nd, I have to do some modifications to use iRedMail too:

Very important for me is how passwords are stored.
Have to migrate an older mailsystem, 52 vdomains, ~4000 user, passwords are MD5 hashes.
So it seems that Dovecot doesn´t use MD5 -> mysql.conf: password-shema = CRYPT
The passwords in the database mapping files also cryptet - I just know this with plain text.
My Q. is, what have I to do, that iRM stores the passwords in MD5[PLAIN] format (not MD5-Crypt, CRAM-MD5 or CRYPT).
Is it enough to modify Dovecots mysql.conf and Postfixadmins config.inc.php [$CONF['encrypt'] = 'md5';]?

A domainadmin for the first standard domain is created well. What I miss is a SUPERADMIN.

Great works, thx twice
