Mail Mappings

Mail Mappings are used to map an external address to an internal address and vice versa. This is useful for hiding internal mail server addresses from external users. For mail originating externally, the mail mapping translates the address in the To: and CC: mail header field into a corresponding internal address to be delivered to a specific internal mailbox.

For example, mail addressed to [email protected] can be redirected to the internal mail address [email protected]. This enables the message to be delivered to the user’s preferred mailbox.

Similarly, mail originating internally will have the address in the From:, Reply-To:, and Sender: header modified by a mail mapping so it appears to have come from the preferred external form of the mail address, [email protected].

To add a mail mapping:

1. Click Configuration > Mail > Mapping .

2. Click the Add button to add a new mapping.

3. Enter the External mail address that you want to be converted to the specified internal email address for incoming mail.

The specified internal address will be converted to this external address for outgoing mail.

4. Enter the Internal mail address that you want external addresses to be mapped to for incoming mail.

The internal address will be converted to the specified external address for outgoing mail.

5. Enter any Extra internal mappings which will be included in the outgoing mail conversion.

Click the Add button for each entry.

6. Click Apply .
