I had trouble identifying which message that applied to but do it believe it may be the right one. I suspect mailauth.nyi.internal is possibly the same machine as smtp.fastmail.com or an internal machine at fastmail that helps process smtp requests. I say that because I get one of those for each email I attempt to send using that config. But anyway, it turns out I needed to make use of the generic table found in the pages you referred me to in a previous thread. I'm only guessing here and I hope you might comment as to whether this is a reasonable guess. I suspect the failure was do to the fact that smtp.fastmail.com could not reserver the domain of the mail sender. My local machine which has a made up domain. Once I put the generic table into play where I have this line: rea...@u0.local.lan hgp...@comcast.net (Left column is my fantasy USER@Host.domain, right column is my address at my IP comcast) Then, sending messages began to arrive at its destination instead of bouncing. Thanks for your kind help. As you mentioned in a previous post, every thing I needed can be found at: http://www.postfix.org/SOHO_README.html , or a link found there. I should have persevered a little longer before posting again, about the mail failures. thread
