Thanks so much for the explanation Viktor. I didn't think it was a
postfix issue but hoped I would get something I could send to the tech
support people to help figure this out. As far as trying another MUA I
get the same error when sending with Evolution. Not every time but more
often than not. It's hard to try and explain something to a tech
support person who knows absolutely nothing about Linux since they're
only oriented towards window and maybe Mac.
