Help needed when removing MailScanner completely

[Mika Leppänen]

I am running Ubuntu Server 18.04 and Postfix. I am trying to get rid of 
MailScanner.

I get these lines in /var/log/mail.err
(After removing MailScanner)

May  1 15:32:30 nix postfix[25014]: fatal: usage: postfix [-c 
config_dir] [-Dv] command
May  1 15:32:45 nix postfix[25018]: fatal: -c requires absolute pathname
May  1 15:32:54 nix postfix/postfix-script[25025]: fatal: unknown 
command: 'spamassassin -x -D -C /opt/MailScanner/spam.assassin.conf 
--lint'. Usage: postfix start (or stop, reload, abort, flush, check, 
status, set-permissions, upgrade-configuration)
May  1 15:39:14 nix postfix/postfix-script[25243]: fatal: unknown 
command: 'spamassassin /opt/MailScanner/spamassassin.conf --lint'. 
Usage: postfix start (or stop, reload, abort, flush, check, status, 
set-permissions, upgrade-configuration)
May  2 21:08:06 nix postfix[6798]: error: to submit mail, use the 
Postfix sendmail command
May  2 21:08:06 nix postfix[6798]: fatal: the postfix command is 
reserved for the superuser

Can you MailScanner gurus tell me how to get rid of this?
