Types of Configurations
Basic Configuration
If your mail server will receive mail for only one domain, read "Checking Configuration of the Primary Host", "Setting Up DNS for the Primary Host", and "Viewing the Basic Configuration". For 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 (entered during installation), so that IMail Server recognizes 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 receives mail for multiple domains (example, for domain1.com and domain2.com), see "Adding an Additional Host".
- If the mail server functions as an SMTP mail gateway for proprietary mail systems such as Microsoft Exchange or CC:Mail, see "Setting Up a Mail Gateway".
- If you have a dial-up Internet connection from your mail server to an Internet Service Provider (ISP), see "Setting up a Dial-up Internet Connection".
- To set up IMail Server as a backup mail server for another server, see "Setting Up IMail Server as a Backup Mail Spooler".
- To spread user accounts across two or more 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 Peering" for more information.
- To specify how your mail server relays mail for other servers, see "SMTP Security" for information.
