7025 connection refused Zimbra error

If you have gotten saddled with the 7025 connection refused Zimbra error, fear not. Our experts are here with the cause and the solution behind this Zimbra error.

In fact, this error is often the result of a host configured on private IP space without an interface for the public IP address the server is on. Fortunately, there is an easy for this issue. All we have to do is use native IP address lookups for LMTP instead of DNS. An alternative method would be to configure the internal network domain name in order to lookup differently internally from how it does it externally.

Additionally, if there is trouble receiving external mail, we have to track down the source of the error. This is done by checking the Log files, including /var/log/zimbra.log, on the MTA server.

If the log contains a line similar to the one below, then there is no connection to port 7025 in order to perform LMTP delivery.

postfix/lmtp … deferred … connection refused

Our experts recommend tailing the log file when we send a message to make it easier to track the issue.

tail -f /var/log/zimbra.log

In case the error is caused by the firewall, we can try to test the issue with an account on a system, outside our network. According to our experts, the inbound mail occurs only when the server on the internet connects to our MTA on port 25.
