From the logs I can see (even though you have obfuscated a lot) that 
quarantine.uwplatt.edu doesn't offer STARTTLS. The plain text authenticators 
normally refuse to send passwords without TLS encryption.

Kindly ask the IT folks if they would consider enabling TLS support. If that 
doesn't work, or if it takes too long, create a file 
in /etc/exim4/conf.d/main/ (README.Debian.html suggests calling it 
000_localmacros) containing

AUTH_CLIENT_ALLOW_NOTLS_PASSWORDS=yes

If that doesn't work, check that passwd.client still has the right permission 
bits.
