I'm running 6.0.2_GA_1912.DEBIAN5_64 and have a problem with uploading files larger then 1MB. Both as attachment and as files in the briefcase.
I did run:
zmprov mcf zimbraMtaMaxMessageSize 10240000
zmprov mcf zimbraFileUploadMaxSize 10485760
But doesn't make a difference. For files < 1MB there is no problem.
Any ideas on this one ?
