SMTP transaction failure

["David Vanderschel" <DJV4@Austin.RR.com>]

I can no longer send email from emacs.  This had been
working for years.  Any insight that might lead to a
restoration of function would be appreciated.  I am
running 20.7 on Windows 98.  See backtrace and
SMTP session buffer appended below.

Things I changed recently:  (These are
probably red herrings.)  I installed a simple
D-Link broadband router.  (However, I have
successfully sent email from emacs on several days
since the router was put in the path.)  I installed McAfee
VirusScan 8.0.  (However, even when I disable it from
starting at startup, I still cannot send email from
emacs.)

I can send email using OE 6.0 with no problem.  I
suspect that my ISP has made some change in the
behaviour of its SMTP servers which has somehow
confounded emacs.

Thanks for any pointers,
  David V.
