I am recieving :
552 5.3.4 Message is too large; 10485760 bytes max
554 5.0.0 Service unavailable
from any emails sent from outside of the zimbra domain. I have gone into the zimbra admin console and changed the max size to 100m, but i still get this error from anyone not in the zimbra domain. On emails going from zimbra user to zimbra user - no problem. Yes I know 100megs is huge - but we have a few mails that need to come through that are that big,. Any help would be appreciated! Is there a way to change email sizes/attachments allowed based on a user's domain as well?
