Then you should tell us what instructions you've followed so we don't go over the same ground again. The first thing to point out is that you obviously missed the setting for "zimbraMtaMaxMessageSize" as you still had the old 20mb setting. Is it you that's sending a test email to your Zimbra server? If it is then what is the exact error that's being shown and is there anything in your ZCS log files that shows this error and if so, what is it?
Instructions above, everybody uses the same commands, and that commands sets something but not te real message size limit, every value I set always ends as 20mb limit.
I have my own VPS server where I have postfix, I use my own domain. In my company I have Zimbra server, and I use company domain. And I'm sending email with 25mb attachment from my private vps to my company mail to test message size limit, and right after that, I reciveing "Undelivered Mail Returned to Sender" mail. Check below to see content of this, mail, I censored my company mail address and my private vpn hostname.

as far I can read from your posts, you're running a cluster of 2 Zimbra server and each Zimbra server is running a Zimbra MTA.
So my question is : did you modify the settings on each server ? If not, you should do this. And you should not have use
since the beginning the legacy postfix commands. My second advice is to use "zmprov mcf" instead of "zmprov ms server_name", but now
it is too late unless you delete the local server configuration per attribute.
Regards,
No, I'm running one zimbra server in my company, and one simply postfix server on my own VPS, coworkers notify me, that some people from outside our company are sending them mails with photos as attachments, but they cannot reach our zimbra server because of 20mb message size limit, which I can't change. I earlier used commands from wiki page which phoenix mentioned, and want to try if it works by sending mail from my own private vps with postfix to company zimbra server.
