Zimbra Mail Error: not enough free space in mail queue

If you are using Zimbra Mail and you are not able to send any mails and also you see an Error Message " not enough free space in mail queue " under /var/log/message. Then you should try out this solution. 1. Login to the server, and then again login as zimbra as follows: #su - zimbra 2. Check the Postfix message_size_limit, by default it should be 10MB (i.e. '10240000' bytes) as follows: $postconf message_size_limit message_size_limit = 10240000 3. If the value is higher than that, set it as follows to 10MB $ zmprov modifyConfig zimbraMtaMaxMessageSize 10240000 $ postfix reload Now try sending Mail, It should work. You could try out this solution for Error: " SMTP Server Reported: 452 4.3.1 Insufficient System Storage "
