Unable to send 'large' email from Zimbra Outlook Connector
Firstly hope I have the right forum as I am a system administrator of the company I work for.
We have a new installation of Zimbra 8.0.2 on a CentOS6_64 install.
We have previously had Zimbra running successfully but never with ZCO, always using either web portal and/or iMap in Thunderbird client. There error is as follows:
Error: This message could not be sent.
Note: File Upload Fault. Please contact your system administrator regarding maximum message and attachment sizes.
Error Code: 413
Error Text: Message is too large
Note: A copy of message is saved in Draft folder without attachments.

None of these images are large in size and we are unable to find the source of this problem...
[zimbra@mailhub root]$ zmprov gacf | grep zimbraMtaMaxMessageSize
[zimbra@mailhub root]$ zmprov gacf | grep zimbraFileUploadMaxSize
From what we can find there should be no issue here but we have limited knowledge regarding this and how to trouble shoot this error.
All help is appreciated,
