I did not.  I opened 587 to the machine (I didn't realize it was closed)

I made modifications to the master.cf file.

I assume you mean -o syslog_name=postfix/submission,  I did that.

Yep, it's reasonable modern.  Double checking here.

smtp       inet  n       -       y       -       -       smtpd
submission inet  n       -       n       -       -       smtpd
    -o syslog_name=postfix/submission
    -o smtpd_tls_security_level=encrypt
    -o smtpd_sasl_auth_enable=yes
    -o smtpd_recipient_restrictions=permit_sasl_authenticated,reject
    -o milter_macro_daemon_name=ORIGINATING

Thanks for reminding me of this.  I found the online copy and I love it when I 
realize something in plain site that has been there forever without my noticing 
it.  (Like the tcpdump command.  I'm going to play with that for sure.)

So the server and thunderbird are talking to each other.  Apparently I don't 
have a password to access the SMTP server I have running.  This must be the 
SASL authentication I've read about in the past.  Dovecot/Squirrelmail 
apparently are able to access it just fine, so I'll look in the config files 
for it.  It must be in there somewhere.
