Thanks, Daniel! That worked:
Code:
[zimbra@power ~]$ zmprov mcf zimbraMtaMaxMessageSize 838860800
[zimbra@power ~]$ zmprov gacf | grep zimbraMtaMaxMessageSize
zimbraMtaMaxMessageSize: 838860800
[zimbra@power ~]$ zmprov gacf | grep zimbraFileUploadMaxSize
zimbraFileUploadMaxSize: 50000000000
[zimbra@power ~]$ zmprov mcf zimbraFileUploadMaxSize 838860800
[zimbra@power ~]$ zmprov gacf | grep zimbraFileUploadMaxSize
zimbraFileUploadMaxSize: 838860800
[zimbra@power ~]$
And thanks, phoenix for the extra info. I didn't know the number was in bits!
(It'd be nice to have add that info to the error message that the number is in bits, rather than bytes or other. I got used to other programs and installers to type in a whole number (ie. 5000000 for 5 megabytes, etc.) or "K", "M" or "G" after the number (ie. 5M, 10G, etc.) and the program would do the conversion for me.
)
I'll mark this as solved.
