If company mails are not delivered to an internal firm server, being therefore only available via POP4.8, you can configure IPBrick in order to unload these mails from the ISP4.9 periodically to a local server. Once they are in this local server the mails are associated respectively to the previously configured accounts. In this way you can configure a server for internal E-mails, even if you only have one, to automate and centralize all firm e-mails (from the Internet and internal).
This feature normally called fetchmail is useful when the MX from the enterprise domain points to another server.
Click on Insert (Figure 4.27) to configure a external server that you want to connect to download email and deliver it in the local server. You have to insert data in the following fields:
Server: Server identification. It could be FQDN and IP address;
Protocol: Protocol that is used by the server - POP3 or IMAP;
Remote domains: Domains that deliver email to the server. It is commonly used in volume email boxes.
To access server definitions, you must click on its name (Figure 4.27):
Modify: To change the account data;
Delete: Deletes the selected account;
Back: Goes back to email servers list.
To access the management interface of remote mailboxes, you must click insert and fill in the following fields (Figure 4.29):
Mailbox type: Select individual mailbox or volume box. A volume mailbox refers to boxes that are not assigned externally to any user, so all mail to all users is delivered in just one public mailbox. In that fetchmail case, IPBrick will get all mail and analyse the to field, delivering mail to the respective local mailboxes;
Login: Used username to access the email remote box;
Password: Needed to validate login;
Retype password: Confirm the previous password;
Local server email: If the individual mailbox is chosen, this field is the local email account where the downloaded emails will be delivered;
Drop 'Delivered-To': If the email address in ISP is the same as the email address in local server, this field must be active.
