Users (of Zimbra Collaboration Suite 6.0) have problems for receive mails with attachments upper to 8Mb!

I followed steps of others thread:


Configuring maxmessagesize - Zimbra :: Wiki

and the current parameters of the server are:

- In the management console -> MTA -> Maximum Message Size (Kb) = 40000
- By terminal:
# Su - zimbra
$ Postconf message_size_limit
message_size_limit = 40960000

the problem persists.. I don't know what another thing I have to change.. Maybe in /opt/zimbra/conf/php.ini?

thanks a lot!
