I think I'm missing some email here from Alan ?
Anyways, LDAP should not be open, it should connect all the time. I
know why a connection is open, it should be faster response but even
than, that wouldn't be a good reason to keep a connection to ldap open
and just crash when it's losing that "only connection".
You cannot monitor this, you can only see it in the logs when LDAP
went gone and you try to access your imap server.
Logging that message might be an idea from the logs, but better
monitoring from dbmail itself would be MUCH better if you ask me.
