Scenario

You want to inform external senders the accounts have been relocated.

Use relocated_maps for the Zimbra MTA

touch /opt/zimbra/conf/relocated

postmap /opt/zimbra/conf/relocated

postconf -e relocated_maps=lmdb:/opt/zimbra/conf/relocated

zmmtactl restart

postconf | grep ^relocated_maps
relocated_maps = lmdb:/opt/zimbra/conf/relocated     <<== you should see this

Example

Edit /opt/zimbra/conf/relocated

The format to use is simple, the old company address first, followed by the new address on the same line.

e.g.

john@example.com          smithj@yahoo.com

Anytime /opt/zimbra/conf/relocated is updated, be sure to run the postmap utility against it.

postmap /opt/zimbra/conf/relocated

Now, anytime someone sends john@example.com a new message, they will get a bounce message back.
