• I wanted to experiment with metasets on my test machine, so Ineeded a local metadb replica . Because Ididn't know about this I didn't have a spare partition, and becauseI didn't know any better I put the local metadb replica in thattempting slice 8

I have recently come to a realization about why this is wrong,and I even have an example.

The problem is that when you give at least a 4xx error to an RCPT TO ,it makes the sending mailer think that there is a problem with
