i.e. every user has a "mailMessageStore" attribute in LDAP that points to his INBOX. Any ideas for how we can migrate user by user to mdbox? Can we add a mailboxFormat attribute to LDAP, and somehow get that used in the user_attrs lookup ? Ideally have it default to maildir if not set, so that the current setup isn´t changed and only migrated users are affected. Or should we be keeping the mailboxFormat as a prefix in all mailMessageStore strings ?
Change user_attrs to:
user_attrs = mailMessageStore=home, mailLocation=mail, mailQuota=..etc..
And in dovecot.conf set:
mail_location = maildir:~/:INDEX=/indexes/%1u/%1.1u/%u
Then add a temporary mailLocation field, which for converted users contains: mdbox:~/mdbox:INDEX=/indexes/%1u/%1.1u/%u/mdbox
Finally once everyone has been converted, get rid of the mailLocation field and instead just set:
mail_location = mdbox:~/mdbox:INDEX=/indexes/%1u/%1.1u/%u/mdbox
As a bonus you then no longer have home=mail directory, which isn't very good anyway, and possibly might make your mailbox migration slightly more difficult than it needs to be.
