Or otherwise perform a storage format conversion?<br><br>I'm presently using sdbox - and considering going back to mdbox though <br>without SIS. My intent now is ONLY a 1-way backup, to be kept current, <br>and no clients will utilize the converted storage (unless/until I change).<br><br>I've successfully executed:<br><br>doveadm backup -u <username> -n inbox mdbox:/var/mail/<domain>/<user>/mdbox<br><br>For a few users - but reading the docs leads me to believe I can <br>automate this. But there's no explicit example for this - so I'm not <br>sure what to set.<br><br>Initially I'm thinking of:<br><br>dsync_remote_cmd = doveadm backup -u %u -n inbox mdbox:/var/mail/%d/%n/mdbox<br><br>and if that's right - which other services/listeners do I need to setup?<br><br>-- <br>Daniel<br><br></body></html>
