I wanted to upload a file in my Zimbra briefcase and got the message that the size is too large (> 36MB).
I search how to increase this limit and got the following results in which I don't see the 36MB limit, can sb explain this ?
*) /opt/zimbra/postfix/conf/main.cf | grep message_size_limit
message_size_limit = 51200000
*) postconf | grep message_size_limit
message_size_limit = 51200000
*) zmprov gcf zimbraMtaMaxMessageSize
zimbraMtaMaxMessageSize: 51200000
*) zmprov gcf zimbraFileUploadMaxSize
zimbraFileUploadMaxSize: 51200000
*) zmprov gcf zimbraMailContentMaxSize
zimbraMailContentMaxSize: 10240000
*) zmprov gacf | grep zimbraMtaMaxMessageSize
zimbraMtaMaxMessageSize: 51200000
*) zmprov gacf | grep zimbraFileUploadMaxSize
zimbraFileUploadMaxSize: 51200000
zimbraFileUploadMaxSizePerFile: 2147483648
You setup a limit of 50MB ( 51200000 ) but mime encoding consumes additional space (137%), so the limitation is 50 / 1,37 = 36MB
Have a look to this doc
