No - sorry - that's not it either... I don't have a "root at localhost..."
email address in the list. Here's the line from smartd.conf: 

/dev/hda -H -m jaymo at mail.bokler.com,root at aria.bokler.com

The email address that bounces (as in the error message above) is the
first one (a valid address). aria is on the "private" network, and has
no dns record anywhere.

It seems the problem is either a) cannot specify a "From:" address for
'mail', or b) I need something else in /etc/hosts (or resolv.conf)
files.

Oddly, my email client on aria is able to send mail just fine. And the
Windows boxes on the network that use 'blat' can send mail just fine.

Puzzledly,
Jay
