CentOS mail (sendmail/mstmp) method summary

Let's take a look at the sendmail mail configuration..

Install sendmail
Run:

The code is as follows:	Copy code
? 1 [root @ vps478753 ~] # Yum-y install sendmail

The program will automatically search for the sendmail installer for automatic installation.

After installing sendmail, run the following command to start sendmail.

The code is as follows:	Copy code
? 123 [root @ vps478753 ~] # Service sendmail start Starting sendmail: [OK] Starting sm-client: [OK]

 
After starting, we can run the mail command to test whether emails can be sent.
1. Send an email through the file content

First, create a body.txt

The code is as follows:	Copy code
[Root @ vps478753 ~] # Touch body.txt

Write content

The code is as follows:	Copy code
[Root @ vps478753 ~] # Echo 'this is test mail'> body.txt

Send email

The code is as follows:	Copy code
[Root @ vps478753 ~] # Mail-s 'test mail' mail@lizhong.me <body.txt

Click to open the content of body.txt.

This is test mail
 
2. Use the MPs queue to directly send the email content

If you do not want to send the email content through the file, you can also send it like this.

The code is as follows:	Copy code
[Root @ vps478753 ~] # Echo "This is test mail" | mail-s 'test mail' mail@lizhong.me

If mail: command not found is prompted
[Root @ vps478753 ~] # Mail-s 'test mail' mail@lizhong.me <body.txt-bash: mail: command not found

The mail command is not installed. In this case, the mail command must be installed.

The code is as follows:	Copy code
[Root @ vps478753 ~] # Yum install mailx-y

Then try again to send the following email!

Send email with mutt

1. Install and configure msmtp

1. Download and decompress msmtp

First use putty and other tools to log on to ssh

The code is as follows:	Copy code
Wget http://downloads.sourceforge.net/msmtp/msmtp-1.4.16.tar.bz2? Modtime = 1217206451 & big_mirror = 0 Tar jxvf msmtp-1.4.16.tar.bz2

2. Installation

The code is as follows:	Copy code
./Msmtp-1.4.16/configure -- prefix =/usr/local/msmtp Make Make install

Note that the directory marked in red is extracted to that directory. I don't know why yum cannot be used for direct installation. An error is prompted.

3. Configure an msmtp account

Switch to, cd/usr/local/msmtp

Create folder etc, mkdir etc

Use vi to create a file and enter vi/usr/local/msmtp/etc/msmtprc. The edit content is as follows:

The code is as follows:	Copy code
# Set default values for all following accounts. ULTS Logfile/usr/local/msmtp. log # The SMTP server of the provider. Account test@163.com # SMTP mail server address Host smtp.163.com # Email sent From test@163.com Auth login # Email server logon account User xiaobaichi@i0554.com # Email server login password Password 123456 # Set a default account Account default: test@163.com

Esc, shift +: enter command mode, enter wq, save and exit.

Because the password is a plaintext, we need to modify the chmod 600. msmtprc permission for this file.

4. Test

The code is as follows:	Copy code
/Usr/local/msmtp/bin/msmtp youremail@test.com

Enter any character and press Ctrl + D to exit and check whether the email is received.

With logs set, you can go to/usr/local/msmtp. log to view the logs. The success or failure of sending emails will be recorded.

You can send an email through the above steps. Here, the email is still sent using SMTP, and msmtp is equivalent to a third-party tool.

II. Install and configure mutt

1. mutt is installed by default in Linux, and CentOS is no exception.

You can use which mutt to view the mutt installation path. If not, use # yum install mutt.

3. Test whether mutt is valid.

The code is as follows:	Copy code
Echo "test" | mutt-s "test" test email address Echo "test" | mutt-s "my_first_test" yangcheng@i0554.com

Sent successfully after testing.

Note: After testing again just now, you do not need to install msmtp. You can directly install mutt to send an email, so that even if you do not have an SMTP account, you can also send an email as usual, COOL
