Once for each mail relay? I think I would prefer to simply not use such a DNSBL. My small handful of mail relays is one thing, but I wouldn't want to be working at a site where mail relays are measured in the dozens and receive the same announcement for each mail relay. I really only need to see it once. > Presumably you have a working postmaster alias on all your relays?

I like that idea in principle, but I'd still simply not use such a DNSBL, if I had to subscribe once for each mail relay. Add a new mail relay, and don't forget to subscribe it to the announcement list. Replace a mail relay, and the new one must be subscribed until the switch from the old one is complete, at which point it should be unsubscribed or else you're causing too much grief for the DNSBL maintainer. ... On the other hand, if something like "[EMAIL PROTECTED]" would be sufficient for all my mail relays, and those of subdomains under concordia.ca, that would be fine, except it's no different than the scenario I described in the first message I wrote in this thread. Actually, it *is* different: mailhost.concordia.ca =~ m/\.concordia\.ca$/ mailhost.subdomain.concordia.ca =~ m/\.concordia\.ca$/ BUT clienthost.concordia.ca =~ m/\.concordia\.ca$/ ... The DNSBL would have to be willing to accept queris from any host in the domain. I still think it would be a performance nightmare, but perhaps I'm wrong .... -- ---------------------------------------------------------------------- Sylvain Robitaille [EMAIL PROTECTED] Systems analyst / Postmaster Concordia University Instructional & Information Technology Montreal, Quebec, Canada ----------------------------------------------------------------------
