Not sure if this question has been ask before, but I still cannot get the satisfy answer for my question. Why I only able to send/receive an email at 7MB in size, while all setting seem to be allow up to 10MB.
Below are parameter that indicating massage size limit on my server:
zimbra@mx:~$ zmprov gacf | grep zimbraMailContentMaxSize
zimbra@mx:~$ postconf | grep message_size_limit
message_size_limit = 10240000
zimbra@mx:~$ zmprov gacf | grep zimbraFileUploadMaxSize
WEBUI >> Global Setting >> MTA >> Maximum Massage Size (KB) = 10000
My config as follow:
OS: Ubuntu 14 64BIT
Zimbra Collaboration version 8.6.0_GA_1153.FOSS Dec 15, 2014
setup: single server deployment.
