I have exhausted all of my skills at debugging this. My Postfix server 
seems to be a relay host. 

My main.cf looks like:
# See /usr/share/postfix/main.cf.dist for a commented, more complete 
version


# Debian specific:  Specifying a file name will cause the first
# line of that file to be used as the name.  The Debian default
# is /etc/mailname.
myorigin = /etc/mailname

smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no

# appending .domain is the MUA's job.
append_dot_mydomain = no

# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h

readme_directory = /usr/share/doc/postfix

# TLS parameters
smtpd_tls_cert_file = /etc/postfix/smtpd.cert
smtpd_tls_key_file = /etc/postfix/smtpd.key
smtpd_use_tls = yes
smtpd_tls_session_cache_database = btree:
${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:
${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc 
package for
# information on enabling SSL in the smtp client.

Logs include entries which look like:

Where did I screw up?
