Looking back, I have a downlink, running NIX that suddenly developed that problem of Bad Password when I send him anything. I can connect with Bob no problem. He has the problem sending to me with the Ddutch.nl domain.

I have sent him a netmail suggesting that.
BTW, here is a log of the session with the bad password.
