There is a persistent mythos -- a worst practice, actually -- among many operations that obfuscating the reasons why messages are rejected is useful. This is wrong.
Consider: either the sender is benign (as in this case) or they are not.
If they're not benign, then either they don't care enough to acquire this information or they do. If they don't care, then providing the information doesn't hurt, because it'll be ignored anyway. If they do care, then they WILL get it, whether by conducting research or by breaching security or by the simpler/cheaper path of paying someone on the inside off.
Please post your password to nanog@. Consider: either we're all benign, or we're not. And if we're not, either we're too lazy to read all the messages to the list, or we're willing to rubber-hose the password out of you. Posting your password to the list is the most logical way to avoid the hose.
I thought we were all educated people on this ML. Please avoid sophism.
