Policy server HTTP error

Symptoms

Attempting to access Webmail fails, and the Dovecot log /var/log/maillog is populated with errors such as:

Policy server HTTP error: connect(127.0.0.1:579) failed: Connection refused

Cause

Dovecot is configured to connect to cPHulk on a server where cPHulk is not running or not enabled. 

Resolution

If cPHulk is enabled, you will want to ensure it's running. You can start it by running the following command:

# /scripts/restartsrv_cphulkd --start

If cPHulk is disabled, you will want to ensure it's fully disabled:

cPHulk Management on the Command Line | Disable cPHulk
