Linux: Mail Server

April 3, 2009 2 comments

Electronic mail (e-mail) is one of the popular services available on Internet hosts. E-mail software comes in two parts: a mail transport agent (MTA), which physically sends and receives mail messages, and a mail user agent (MUA), which reads messages and prepares new messages.

sendmail’s configuration file /etc/mail/sendmail.cf in Fedora and /etc/sendmail.cf

The sendmail mail transfer agent, you can use the mail command to compose and send a mail message to any user account on your Linux system. As a test, compose a message and send it to yourself.

For example,
mail edulaney
Subject: Testing e-mail
This is from my Linux system.

.Cc: but leave that blank.

After ending the message, the mail user agent passes the message to sendmail (the mail transport agent) for delivery to the specified address. sendmail delivers the mail message immediately.

To verify the delivery of mail, type mail to run the mail command again and read the message. Thus, the initial sendmail configuration file is adequate for sending and receiving e-mail, at least within your Linux system.
