The mail window contains all settings necessary for connections between the internet and the internal mailserver. Also the DNS server (to be used for blacklist querying) and the mail forwarding options are defined here.
- Incoming mail
- Outgoing mail
- DNS Server
- Enable forwarding to multiple mailservers
- Domain list
- Add forwarder
- Delete forwarder

The incoming mail properties represent the ip numbers and the port on which Pinjo should be listening. By default Pinjo will listen to all IP numbers assigned to your server. The pulldownbox 'Listen IP number' contains all available IP numbers on your server. When selecting one and clicking the Save button, new settings will be applied and saved.
The outgoing mail properties represent the ip numbers and the port where Pinjo should sent the checked mailmessages. When clicking the Save button, new settings will be applied and saved.
This is the IP address of the DNS server that Pinjo will use for the blacklist lookups. This doesnt need to be the same DNS server that you use on your system.
Enable forwarding to multiple mailservers
If enabled (checked) the lower pane is active and mail will be forwarded according to the rules defined. The * domain cannot be deleted from the list and will always be active. All undefined mail will be forwarded to the default mailserver configured in the Mail window.
In this list the different domains and mailservers Pinjo should forward your mail to can be comfigured. A match is done between the email-address and the domain list. If you enter a domain like '.com' all email adresses ending with '.com' will be relayed. This is obviously not a good solution. So more specific entering of domains is recommended like 'acme.com' or '@acme.com'.
The Add forwarder button adds 1 extra empty field in the list. Non used empty fields will not be saved.
The Delete forwarder button deletes the current active row from the Domain list
