I have Zimbra 8.0 i'm migrating account from other server but the account the .tgz files have between 800MB and 3.8GB i haveing problems. I've change
zimbraMtaMaxMessageSize
zimbraFileUploadMaxSize
to 4GB but always i get the same error.
Note: after any change in the config always restart with zmcontrol restart
Try this command
/opt/zimbra/bin/zmmailbox -z -m user@domain.com postRestURL “//?fmt=tgz&resolve=reset” /tmp/account.tgz
Or, if you are still having problems, you can use CURL method
curl -k -u admin:PASSWORD --data-binary @/path/to/USER-account.tgz "https://MAILSTORE-FQDN:7071/service/home/USER@DOMAIN/?fmt=tgz&resolve=skip"
