Hi All, I am using the open source zimbra for my small organisation, v4.5.6_GA_1044.


Basically I want to set the system such that:

1. For internal mail, example from xxx@internal.corp to yyy@internal.corp, the max message size is 10MB

2. But, for internal to external mail or vice versa, the max message size is 4MB


Is this possible, has anyone done it with Zimbra?
