Recommended spam.lists and/or sendmail dnsbl settings?

[Duncan, Brian M.]

Thanks for confirming that for me.

So is this not a feature that would benefit many users?

The capability to have MailScanner NOT check ALL RBL's but in an order
based on how many the admin wants till it equals a failure?

It seems kind of inefficient to check ALL RBL's listed if an admin
trusts results from specific RBL's.

Like in my case I could avoid probably 80% of my queries to zen with
this capability.

"The Spam Lists To Be Spam" directive could still be set, but
MailScanner could quit RBL checks after meeting that condition.

It could even increase performance couldn't it for heavily loaded mail
servers?

In my organization we rely on MailScanner to do the RBL checks and pass
ALL mail through to end users (We need to, they can never afford to miss
a message)  RBL failed messages are considered high scoring spam and get
a slightly different identifier to quickly identify an RBL'ed messages
from one that failed do to message content.
