## 30.2 Dial-up Line + Domain Mailbox

### Information and Requirements

1. The company uses the domain `othercompany.com` and all messages sent to this address are stored in a domain mailbox entitled other company at the server `pop3.isp.com` with the username `othercompany` and password `password`

2. Internet connection is via a dial-up line

3. The ISP enables sending outgoing email via their server

   `smtp.isp.com`,

   if the user authenticates by username and password (the same situation as in case of POP3).

4. During working hours (Mon-Fri 8:00-17:00) mail will be downloaded every hour and after working hours at 20:00, 0:00 and 5:00

### Implementation

1. In the Configuration → Domains section, create the primary local domain `othercompany.com` and set the Internet name of the server `mail.othercompany.com` (this is more or less fictitious but it contains the domain name). The domain is defined as local, which means that mail sent between local users will not be sent to the Internet and downloaded back again.

2. In the Domain Settings → Users section, create user accounts for all local users.

3. The server will connect to the Internet using a dial-up connection (that already exists in the system). In the Configuration → Internet Connection section, choose the Offline option, tick the field Use RAS to connect to Internet, choose the requested RAS connection and enter the appropriate username and password.

4. All outgoing mail will be sent to a relay SMTP server. On the SMTP Delivery tab in the Configuration → SMTP server section, select Use relay SMTP server and enter its name — `smtp.isp.com`. The server requires authentication — enable the option Relay server requires authentication and fill in the appropriate username and password. Set the authentication type to SMTP AUTH Command.

5. In the Configuration → POP3 Download section, Accounts tab, define downloading of the domain mailbox othercompany at the server `pop3.isp.com`. Mail from this mailbox will be delivered using sorting rules — select Use sorting rules. It is recommended to consult selection of a preferred header with the administrator of the server where the mailbox is located. The default Received header should be suitable in most of situations.

6. In the Configuration → POP3 Download section, Sorting Rules tab, set sorting rules for individual users' email addresses.

7. In the Configuration → Definitions/Time Ranges section, create a time interval Working hours, containing the range 8:00:00-17:00:00 valid from Monday through Friday, to be used in scheduling.

8. Set up scheduling for message retrieval from the POP3 box and sending of messages from the mail queue. Add scheduling for every hour (Every 1:00) valid at the time interval Working hours and three schedulings for certain times (At) that will be valid all the time. For all schedulings tick the Receive POP3 mailboxes but also Send mail in mail queue.
