POEST::Plugin::Check::Hostname - Check for a proper host in HELO.
Check for a proper host in the HELO command sent from the client.
Intercept the HELO event. If configured to require a hostname in the HELO sent by the client, it will check the acceptible hosts list for the host specified. If said host is in the list, execution will continue on to the standard HELO implementation that greets the client. If it fails, an error will be sent to the client.
If true, a specified (and correct) host will be required. Otherwise these checks will be bypassed. Kind of useless without this, isn't it?
This option has multiple values. A list of hosts that are allowed for this SMTP server.
