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?
