No, I didn't - and I don't think you should have to either.  I've just
tested it specifically with mail, on my work Solaris box, under bash, and I
don't need the echo.  I only put the echos in to include either a blank line
(between the header(s) and the body) or literal strings...

I'm not sure what you mean by this...  You are using bash, I assume?  The
mail you get/send should look just like what you get if you send the output
from each of the commands to a file, using append (>>).
