I just noticed some entries in my greylist for mail from the outside world destined for domains that aren't mine and thought "Oh oh, am I an open relay?"
I quickly determined that I'm not, so I thought I'd try to understand why
messages which will be denied due to relaying are even touching my greylist.
After all, check_relay is up near the top of my plugins file.
So, I determined that all check_relay does is to set the relay_client flag and
a test for rcpt_hosts doesn't happen until rcpt_ok (which must be run last).
Why doesn't rcpt_ok just return(OK) and the logic for testing rcpthosts get
moved to check_relay?
