Thanks for the help. I've tried adding the hosts_require_auth option
in the file /etc/exim4/conf.d/transport/30_exim4-config_remote_smtp_smarthost:

remote_smtp_smarthost:
  debug_print = "T: remote_smtp_smarthost for $local_part@$domain"
  driver = smtp
  hosts_require_auth = smtp.nw.uwplatt.edu
  hosts_try_auth = <; ${if exists{CONFDIR/passwd.client} \
        {\
        ${lookup{$host}nwildlsearch{CONFDIR/passwd.client}{$host_address}}\
        }\
        {} \
      }
[file continues...]


Now when I try to send a message, the SMTP exchange is shown below. Is the problem with the smarthost server? Thanks for any help!
