Add it as an IP Block List Provider in the Edge Server's Configuration:

The provider name is 'Spamhaus', the lookup domain

Thanks!  How do I know if its working?  Will the rejected e-mails be sent to the quartine box or will they just be blocked?

You won't get much spam, and an RBL (in conjunction with other anti-spam techniques) means message tracking logs won't report an inordinate number of emails accepted and then NDRs sent.

The messages won't be quarantined, since the RBL is checked the moment the remote server connects. If its IP address is a positive match for an address on the RBL match, the session is immediately dropped by the server; no further communication takes place - the message is never transmitted to your server.

The intention behind this being that very little bandwidth, CPU cycles and processing time is used to handle the inbound connection, which, if listed on an RBL, is most likely to be spam mail anyway.

This is simply the nature of an RBL and the way in which it is implemented,
