POP3

You can set up an SMTP/POP3 server to accept mail for your domain (for example, user@domain.com).

All the mail is delivered to the SMTP/POP3 mail server. Every other host has a POP3 mail client which they use to read their mail.

Outgoing mail is composed using the POP3 mail client which sends the message to the SMTP/POP3 mail server. The mail server then translates this POP3 message into SMTP and delivers it via the Internet.

Proprietary Mail Protocol to SMTP E-mail Gateways

If you already have an internal mail package running like Microsoft Mail or QuickMail, you can set up an SMTP gateway.

SMTP gateways allow you to integrate your current internal Mail package with Internet SMTP mail.

Internal mail packages use their own message format and transmission guidelines. Because internal mail does not use SMTP, an internal mail message cannot be sent over the Internet.

The SMTP gateway takes an internal mail message and translates it into SMTP so it can be sent over the Internet. The SMTP gateway also translates incoming SMTP messages into a format that can be read and understood by the internal mail package.

UNIX sendmail

If each host on your network is capable of sending and receiving SMTP mail directly, you can have individual machines receive e-mail. This requires each individual machine to have a unique MX record.

For example, assume your domain name is domain.com, Carol has a host named aries.domain.com and Frank has a host named gemini.domain.com.

To send mail to Carol, the e-mail address might be carol@aries.domain.com. To send mail to a particular host, the e-mail address has to contain the host name.

In this case, one machine can be set up to accept mail for the entire domain and "forward" it on to individual machines. This is generally implemented with UNIX Sendmail.
