Huh, I am not familiar with how to use /etc/hosts as a DNS source. Can you
clarify?
Mainly my question was if/how I could avoid making it a DNS query. I'd like
to simply hand spamc the two addresses that I want it to have manually, and I
do *NOT* want round-robin, I want failover....
Your help is much appreciated!
