/usr/lib/postfix/smtp: bad command startup -- throttling

Dear knowledgeable ones,

    I have just installed postfix and have some teething problems. This
message keeps being displayed:

Aug 13 15:41:20 p2aa-app046 postfix/master[4555]: warning: process
/usr/lib/postfix/smtp pid 5394 exit status 1
Aug 13 15:41:20 p2aa-app046 postfix/master[4555]: warning:
/usr/lib/postfix/smtp: bad command startup -- throttling

The mail server should just forward all email to its mail replay, which
I set in the main.cf as :
relayhost = 10.123.12.6

Perhaps the smtpd is not installed correctly : Above it states that
/usr/lib/postfix/smtp is a bad command, which is surprising because this
does exist:
# ls -l /usr/lib/postfix/smtp*
-rwxr-xr-x 2 root root 92780 Feb 23 2009 /usr/lib/postfix/smtp
-rwxr-xr-x 1 root root 154432 Feb 23 2009 /usr/lib/postfix/smtpd

The mailq is not decreasing.

-- end of postfinger output --

For debugging purposes I added this to the main.cf:
debugger_command =
         PATH=/bin:/usr/bin:/bin;
         (strace -p $process_id 2>&1 | logger -p mail.info) & sleep 5

And added the -D to smptd and did a 'postfix reload', but it did not
actually do anything :( Worth a try.

I know that it is a Friday, but can anyone shed some light on this problem?

Best wishes, S.
