Block IMAP ports on the firewall?

Hi Julian,

For migration solution in production I wrote a big Script that, the main steps (in this mail without error handling):

1.) Copy the complete user account to the new box by rsync (rysnc is faster than doveadm backup). 2.) Update new destination in a loop (min=2, max=10, retry on error 75): doveadm backup -u $USER tcp:${NEW_MBOX}:${DADM_PORT} 3.) Change LDAP to new destination and kick user on old box. 4.) Call a latest sync for possible new mails on old box: doveadm sync -1 u $USER tcp:${NEW_MBOX}:${DADM_PORT}"

The Script has migrate millions of accounts in production. I use "parallel" to optimize the runtime.

Hi all,

what is the best way to temporarily disable access to a mailbox via imap, but keep it possible to deliver to the mailbox via lmtp? I want to migrate some mailboxes around and would like to ensure that the users cannot access their mail while doing so. I would like to keep the users from logging in entirely rather than setting ACLs.

Thanks in advance Julian
