Mail sending size limit.

We want to restrict email, attachment, and file upload sizes. Users cannot upload and attach a file of more than the defined size. Mail size should be limited to the defined size.

I was trying to figure it out as well. Here is what you need to do:

Run this as zextras:

$ postconf message_size_limit

It should come back with

message_size_limit = 10240000

To change it, as the zextras user (BTW 20000000 is 20 MB):

$ zmprov modifyConfig zimbraMtaMaxMessageSize 20000000

$ postfix reload

Then run:

$ postconf message_size_limit

It should come back with:

message_size_limit = 20000000

Good luck!

@keithwmd Thanks for your reply. We will try it out.
