Hi all,

I need to move e-mail files of my users from one file system to another.

I use a MySQL backend on Dovecot 2.1.

How can I do to disable temporary an account while moving files ?

I have an "active" bit in my DB, but if I set it to 0, my MX servers are bouncing mails.

How can I do to disable temporary an account ? In fact, I need dovecot not to do any change on files...

I think I could change account password for a while, and reset it after migration, but it will disturb connected users.

Maybe I could chmod 0 files on my old file system during migration ? How Dovecot will act ?

Thank you :)

and/or

if your user has static ip use firwall to reject ( be aware of nat )

and/or

change behave of sql active table with i.e postfix to tmp fail etc

i.e ( dont copy paste ,must fit to your postfix(sql)config !!! )

smtpd_recipient_restrictions = reject_unknown_recipient_domain, reject_non_fqdn_recipient, permit_mynetworks, check_recipient_access mysql:/etc/postfix/mysql_virtual_inactive_mailaddress.cf,

mysql_virtual_inactive_mailaddress.cf

... query = SELECT CONCAT('421 mailaddress %s is set in inactive mode') address FROM mailbox WHERE username='%s' AND active = '0'

be aware of all other involved postfix/sql tables where active = 0 is honored too, do hard testing before use in production

after all change password might be the most easy way for only seconds

Thank you very much Robert.

I also had a look at "dsync" tool. But I think it handles only mails directory, and not all user's home (my users's home contains indexes, Maildir and sieve directories).

stop mail server daemons (you DO have a backup MX I hope if you only have one mail server), rsync, (or if theres not much, sshfs and "cp -a") start mail server daemons.

if this is a different machine, with new IP, hope you changed your DNS to TTL 0 - and did it at least 24 hours ago so changes are picked up right away (dont forget to reset TTL to 1D again)
