I made modifications to the master.cf file.

To get one, you need an entry similar to this in
your
master.cf file:

submission inet  n       -       n       -       -       smtpd
    -o syslog_name=postfix/submit

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

syslog_name can be any reasonable ASCII token you like. Its only purpose 
is to distinguish different configs of the same running binary in system 
logs. I prefer the shorter syslog_name, but it's not unreasonable to 
match the service name.
