Yes all that is functional. No problem for this part.
for the migration, i am using a database used before, with the postfix
configuration files which were used before. Then no problem with the
postfix 's configurations (except some elements resolved now).

Except that, the problem is that i can't configure the account with
differents MUA like usually, and the ancient configured email accounts
can't no more connect to this email server.
Before, the email accounts (which are the same actually than before, cause
the same database) were functional, the ID for the authentication were
configured with "user@domain". Now, i ve to remove the @domain for that it
be functional on MUA. I tryied too a modification on the database on the
"user" part on virtual_users, i modified eg. "user" by "user@domain", and i
can connect like before the new server. But i can't modify all users (the
database is used for others dev requests) like that.if i do ,that i can't
send emails.

But i would want to modify the mysql-virtual-mailbox* files for that it
understand "user@domain" request and not the "user" request. it was
functional before, and nothing was modified.

This is the reason of my request. Is it possible? Maybe there's a mean to
do that ?
