Mail error

[Matthew Carpenter]

I'm not sure why you would be getting AUTH errors unless you had
configured SMTP AUTH on the box.  If you had done that, I would have to
ask why....  Unless you are pumping all outbound mail through a provider
which requires SMTP AUTH (like Yahoo.com) then I don't see a whole lot of
use for SMTP AUTH.  If you are attempting to establish email communication
in which one or both parties are identified, I would recommend using SMTP
STARTTLS using CERTS and a CA, which will provide both encryption as well
as positive ID.  If you are working AROUND something, then you'll have to
dig deeper in the SMTP AUTH manual to only use SMTP AUTH for specific
sites, which I have no knowledge about.  Good luck!
