 RBLs and Graylisting
Sorry man, call me dumb, but graylisting? Is that the same as RBLs?
mmorse, you've made mention of the RBLs being redundant, and the one referred to as mail-abuse.org is now Trend Micro premium service.
Questions about RBLs...
Someone else mentioned that spamassassin uses the "RBL DNS lists" already. Uhhh... Which one of this list of RBLs is that?
The list...
dnsbl.njabl.org
cbl.abuseat.org
bl.spamcop.net
dnsbl.sorbs.net
sbl.spamhaus.org (or zen.spamhaus.org)
relays.mail-abuse.org (no longer in service - now trend micro owned)
I guess my bottom line question - if you or anyone knows - which RBLs are valid to use on a system that doesn't get a lot of training by its users, but is several months old?
The Trend Micro RBL... Any experience, or feedback as to how effective it is for folk? We're a Trend Micro reseller and I've submitted a request for use of their service. Thought I'd check it out and do some tests, unless it's been reviewed and rated by a knowledgeable and credible source.
I believe adding more RBLs is an overhead to the email server and increases our bandwidth. I just want what's effective, not taxing and redundant.  |
