CentOS - Mar 2012 - Postfix problems with maximum messages size

CentOS-6.2

I am confused.  I need to accept messages somewhat larger
than the default 10M allowed by Postfix.  However,
changing the message_size_limit in /etc/postfix/main.cf is
having no effect.

Squirrelmail is configured to accept and transmit messages
up to 24M and this identical configuration is working on a
Sendmail installation.  So the problem appears to me to be
strictly at Postfix matter.

# grep message_size_limit /etc/postfix/*
/etc/postfix/main.cf:message_size_limit = 20480000

# postfix reload
postfix/postfix-script: refreshing the Postfix mail system

# postconf -n | grep size_limit
message_size_limit = 20480000

smtp message generated to squirrelmail client

Message not sent. Server replied:

    Requested mail action aborted: exceeding storage
allocation
    552 5.2.3 Message exceeds maximum fixed size (12000000)

What is going on?  Why am I unable to have configured
limit of 20M take effect?

And did you change mailbox_size_limit in main.cf

I had a same problem but  i am using zimbra firstly i did in zimbra sudo 
su - zimbra #(or just su - zimbra)
zmlocalconfig -e imap_max_request_size=102400000
zmprov mcf zimbraMtaMaxMessageSize 102400000
zmmailboxdctl restart

and then i changed main.cf of postfix like you , but opposite host of 
user domain postfix did not accept mail because of 10mb limit.
Conclusion
be sure which postfix returned this error to you (your server, or from 
other side) and be sure your mail program (thunderbird, evolution etc.) 
has not limit of 10 mb

and also you must add uploaded file size settings in main.cf (if you 
attach a file)

and be sure service has been restarted
