Linux (CentOS) postfix server dovecot receive mail

First, the installation of Dovecot to receive mail, using the RPM method after installing the Dovecot software, you need to undergo some changes to normal use.

First, install Dovecot directly using the system's Yum source

Yum Install Dovecot

Modifying a configuration file

1. Modify in/etc/dovecot/dovecot.conf

Protocols = protocol supported by IMAP POP3 LMTP

Login_trusted_networks = 192.168.10.0/24//Specify the network segment address that is allowed to log on

This will not prompt for password authentication failure when using Outlook client login.

The error code is:dovecot:pop3-login:disconnected (tried to use disabled plaintext auth): rip=192.168.10.11, lip=192.168.10.1< /c0>

2. Remove the/etc/dovecot/conf.d/10-mail.conf in the

Mail_location = mbox:~/mail:inbox=/var/mail/%u

The preceding comment, which is to enable the line,

Remove it from the/etc/dovecot/conf.d/10-auth.conf

Diable_plaintext_auth = yes

The previous comment. and change Yes to No

Then exit the config interface and switch to the mail user, such as SU-AAA switch to AAA user

Create a directory under the current user's home directory

Mkdir-p Mail/.imap/inbox

If you do not create the directory, you will be prompted for authentication failure (-err Authtication failed) when using Telnet to log in to Dovecot. The error code is:error:couldn ' t open inbox:internal error occurred. Refer to server log for more information.

When configured, start Dovecot

Service Dovecot Start

You can use the Telnet command to receive the message, as shown in the test process.

Telnet 192.168.10.1 110

Second, for the Postfix service to open the user alias support:

1. Open Hash-based alias file support in config file

In MAIN.CF, locate the following command, and then enable it (that is, remove the previous # number):

#alias_maps = hash:/etc/aliases

2. Define a new alias entry in the/etc/aliases file, usually in the format of two fields separated by a colon, the original target email address, and the last field to the address that was actually sent to, such as:

Aaa:fei said to [email protected] mail, all forwarded to [email protected]

3. Convert/etc/aliases to hash format:

#newaliases/etc/aliases

Error prompt: Newaliases:fatal:alias initialization mode requires no recipient

The cause of the error is that the newaliases does not require parameters and is entered directly, i.e.

#newaliases

4. Let postfix reload the configuration file

Service Postfix Reload

can be tested;

Using Dovecot to enter the receiving letter, you can clearly see the message displayed: Delivered-to:[email protected], but the login user is [email protected].
