Hi,
What "postfix" server? Did you check the limit in that postifx?
The commands given to you work, if they are not working for your zimbra, is not a thing with the commands but my guess would be with your configuration instead.
Defaults for zimbra are not "20MB" either, so maybe, that "postfix" server is configured that way. Please make sure that's not the case.

Re: Zimbra incoming message size limit
My private server has nothing to do with this problem, it is configured to send large attachements to test Zimbra max attachement size setting. If i am able to send large email then it is configured properly, errors are coming from server with Zimbra, not my private Postfix. If i try to send 23MB attachement from my private GMail account to my server with Zimbra, I still gets same errors (gmail returns: 552 Requested mail action aborted: exceeded storage allocation. Before unnesesery questions - I have unlimited mailbox size, and plenty of free storage,). So that's definitely not the case.pup_seba wrote:Hi,

Re: Zimbra incoming message size limit
Have you looked at the receiving server to determine its max size? It will tell you if you issue an ehlo verb via its SIZE response.
So gmail has an incoming limit of 157MB... Yahoo is: 42MB in comparison.
If you have determined that the SIZE is what you set it to in the receiving zimbra server.... Look to see if you have an appliance that is transparently intercepting your email. It not unheard of in these forums to have a FW do that and that can add to the confusion.

Re: Zimbra incoming message size limit
Ok, so i tryied your suggestion. When I telnet to my zimbra server it says that message size limit is set correctly, I set 62mb and it says "250-SIZE 62914560", but server still responds with errors when reciveing messages larger than 20mb. So, you said to see if firewall is not a relay server. Yes it is. We have Watchguard Firewall in company, I checked incoming SMTP proxy and bingo! It was set to 20mb, so firewall controls max mail message size instead of zimbra. I would never have thought about that.JDunphy wrote:Have you looked at the receiving server to determine its max size?
