It was most certainly not obvious, not to me. It's bad advice to
give to anyone, and definately to a novice to test relaying from the
local machine. As I've explained in my previous mail, by default
most mail setups allow relaying from the local machine.
"when you're talking specifically about mail relaying, you
can do basic testing (which is pretty much all you should need)
right from localhost"
You're trying to tell me, that you implied there to attempt to relay
"from an IP that your MTA is supposedly configured to not permit
relaying from". You basically said a person can test for an open
relay from the localhost. I said you can't. More accurately, I
said you shouldn't, because it is not a valid test for the vast
majority of setups.
I don't wish to continue this discussion any further. If you
maintain that it was obvious, than simply take my mail as a
qualification to other observers that it may not have been as
I think if anything, I've been rather polite with my responses over
