How to change maximum size of message

Dear all,

I use PMX version 5 on Linux 4, I have the following problem: our users can not send or receive the emails with attached file is larger than 10 MB because my Postfix mail server has been rejecting them. I changed the option "message_size_limit" from 10240000 to 20480000 by the command "postconf -e message_size_limit=20480000". I also added the option "message_size_limit = 20480000" in file /opt/pmx/postfix/etc/main.cf and then I restart postfix service. However, when I use command : "postconf -d", I still see the option message_size_limit is 10240000. And the email which is larger 10 MB is still rejected.

Does anyone have any idea or suggestion ?

Thanks,

Hut

Hi .. finally i can solve this issue :smileyhappy: actually this is not PMX issue, since you can see the changes if you telnet PMX like my previous post .. the limit size was came from SEA .. :smileyvery-happy:, change the policy smtp option for global size limit then .. viooollaaa .. user can send email more than 10 MB ..
