First of all please do *not* toppost.   go through the mailing list
guidelines that you agreed to when you signed up for this list.

Please *explain* why (with reference URLs) you keep mentioning courier
quota option when your SMTP server is postfix.

postfix != courier; to the best of my knowledge it's configuration
file is main.cf.

Keep in mind that there are many postfix addons that may not be built
into the standard CentOS postfix package.

This does not make sense to me.   yes implies override the limit, have
you tried setting it to no?

Besides it does not appear in this list
<http://www.postfix.org/postconf.5.html> suggesting that it is an
extended parameter from an add on patch; so that may be your problem.

The output of 'postconf' will show you the parameters that postfix is
honoring irrespective of what you have put in main.cf.

I would strongly suggest that you look for clues in the postfix log
files found under /var/log/ and also look through postfix
documentation <http://www.postfix.org/documentation.html> for the
stock parameters.   From what I have seen, quota on maildir style is
not standard in postfix but provided by 3rd party patches.
