Oops.
dbmail-users -d username basically doesn't do anything but DELETE FROM
dbmail_users where userid='username', but because of the ways the tables
are setup, this will trigger several cascades.
The main ones that will interest you are:
dbmail_users -> dbmail_mailboxes -> dbmail_messages.
Until you run dbmail-util, the actual messages will still be there: in
dbmail_physmessages and dbmail_messageblks. So do *not* run dbmail-util
until you resolve this. And backup you data!
It should be possible to reconnect all unconnected physmessages to a new
messages and reconnect those to a new mailbox.
create a new user that will contain the rescued messages.
- insert into dbmail_users (userid,passwd) values
('newusername','password');
find the user_idnr:
- select user_idnr from dbmail_users where userid='newusername';
this will give you $newuser_idnr
create a mailbox for this user:
- insert into dbmail_mailboxes (owner_idnr, name, seen_flag,
answered_flag, deleted_flag, flagged_flag, recent_flag, draft_flag)
values ($newuser_idnr, 'INBOX', 1,1,1,1,1,1);
find the mailbox_idnr for this mailbox:
- select mailbox_idnr from dbmail_mailboxes where
owner_idnr=$newuser_idnr and name='INBOX';
this will give you $newuser_inbox_idnr;
Ok, now the real work:
find all unconnected physmessages that may have belonged to the deleted
user.
- select id from dbmail_physmessage p left join dbmail_messages m on
p.id=m.physmessage_id where m.physmessage_id is null;
- for each physmessage.id found thus create a new message:
- insert into dbmail_messages (mailbox_idnr, physmessage_id)
values ($newuser_inbox_idnr, $physmessage_id)
After this you should be able to login to dbmail-imap with the newuser's
id and password and see the messages.
But like I said, this will *only* work if you haven't run dbmail-util
since the accidental deletion.
