Hey,
Don't know how it happened, but either sendmail (from RH)
hasn't been secure from my last install, or in dealing with all
my hassles getting my private network working opened sendmail up
to others. For some days spammers were relaying through my
server.
In the end, I had to completely shut sendmail down & am using
my isp's smtp server.
Two questions:
1. As I don't remember the commands one enters from another
client to attempt to relay through a server, can someone provide
me with those?
2. I'm looking at a sendmail config to not only illiminate
relaying except for specific clients, but also to simplify
sendmail's config. Does anyone have enough sendmail knowledge to
verify the info here:

Sure, it's from Linux Gazette, but the sendmail.cf looks too
simple to me (I may just be conditioned by sendmail's over
complication of things, though).
