but that's no reason DBMail dying when you reboot the LDAP server

you really don't want to restart services left and right on other 
machines after you reboot the LDAP server after as example a kernel update

as said: sometimes servers needs to be rebootet and stable services 
should just reconnect or *really* die not just stop working, if DBMail 
can't recover after lost of the LDAP connection it should just exit with 
a error-status when it no longer works at all

in that case at least supervisors like systemd could restart it 
automatically
