Types of Configurations
Basic Configuration
If your mail server will receive mail for only one e-mail domain (for example, for mail addressed to domain.com), read the sections "Checking Configuration of the Primary Host" and "Setting Up DNS for the Primary Host", and "Viewing the Basic IMail Server Configuration". If you need background information on DNS servers, see "Appendix A: Mail Servers and the DNS" in the IMail Server Getting Started Guide.
Advanced Configuration
Depending on your mail requirements, you may want to read some of the following advanced configuration topics:
- You can set up an alias for the official host name (that was entered when installing IMail Server), so that IMail Server can recognize another name as valid. For example, you could set up an alias so that both user@mail.domain.com and user@domain.com are valid addresses. To set up an alias, see "Setting Up an Alias for a Host".
- If the server will receive mail for multiple domains, each with its own set of users (example, for domain1.com and domain2.com), see "Adding an Additional Host".
- If you want your mail server to function as an SMTP mail gateway for proprietary mail systems such as Microsoft Exchange or CC:Mail, see "Setting Up IMail Server as a Mail Gateway".
- If you have a dial-up Internet connection from your mail server to an Internet Service Provider (ISP), allowing you to receive mail from an account with your ISP, see "Setting up a Dial-up Internet Connection".
- If you want to set up IMail Server as a backup mail server for another server, see "Setting Up IMail Server as a Backup Mail Spooler".
- If you want to spread user accounts across two or more physical computers, you can set up "peer" servers. For example, mail sent to domain.com is processed by both host1.domain.com and host2.domain.com. See "Setting Up "Peer" IMail Servers" for more information.
- If you want to specify how your mail server relays mail for other servers, see "Chapter 6: SMTP Security" for information.
