Hi!
Nope, I'm not confused. I've had to whitelist outgoing mail servers of major major Swedish ISPs after they got listed on dsbl. Those servers where not open proxies or globally open relays.
Unless you believe that the dsbl "trusted users" can be 100% trusted to not make mistakes, or that there are no computers infected with viruses that install proxies configured to relay throgh the default outgoing mail server rather than direct to MX, or any other unforseen new issue, there is a risk of FPs in dsbl.
Didnt experience that, was that recently ? Anyway, sure, everybody can make mistakes, but so far i didnt see many in DSBL actually...
Guess you were 'lucky'
Bye, Raymond.
