I posted a similar question almost a month ago.

In this time I did not any step forward .

I searched for files containg the words size or limit in /opt/zimbra (and its descedants,) but I had no luck.

I expose again in two words my issue: in the system where I am developing all works fine but in the production server when I try to upload video files (20MB or so) it doesn't work while a short text file is receveid correctly.

I thought it is a simple config issue. I am quite surprised nobody had the same problem in the past.

The development machine has Ubuntu while the server has a Fedora Core.

I hope somebody can save me.

Thanks

PS A firewall?
