Dovecot+mysql pickup service and shell mail

1.yum install dovecot dovecot-mysql.x86_64-y

# # dovecot is an open source IMAP and POP3 mail server that supports Linux and email

# # dovecot-mysql is a plug-in for dovecot to let dovecot recognize MySQL

2. Vim / etc/dovecot/dovecot.conf

24 protocols = imap pop3 lmtp # # supported pickup protocols

48 login_trusted_networks = 0.0.0.0amp 0 # # trust any network

49 disable_plaintext_auth = no # # enable plaintext authentication

3. Vim / etc/dovecot/conf.d/10-auth.conf

123! include auth-sql.conf.ext # # enable MySQL authentication

4. Cp / usr/share/doc/dovecot-2.2.10/example-config/dovecot-sql.conf.ext / etc/dovecot/dovecot-sql.conf.ext

# # generate dovecot and read MySQL configuration

5.vim / etc/dovecot/dovecot-sql.conf.ext

32 driver = mysql # # Database Type

71 connect = host=localhost dbname=email user=postuser password=123 # # query database, user and password

78 default_pass_scheme = PLAIN # # the default authentication method is plaintext

107 password_query =\ # # query password match

108 SELECT username, domain, password\ # # query user, domain name, password

109 FROM emailuser WHERE username ='% u 'AND domain ='% d'# # query from the emailuser table

125 user_query = SELECT maildir, 666 AS uid, 666 AS gid FROM emailuser WHERE username ='% u'# # query the internal content of the email

6. Vim / etc/dovecot/conf.d/10-mail.conf

30 mail_location = maildir:/home/vmail/%d/%n # # specify message location

168 first_valid_uid = 666 # # query user identity by email

175 first_valid_gid = 666

7.systemctl restart dovecot.service # # restart the dovecot service

* * Test

8. Shell mail

Vim / etc/postfix/main.cf

Myorigin = westos.com # # set to the real host domain name

Mydestination = # # Shell mail does not accept mail, so do not set

Relayhost = 172.25.254.174 # # IP of the real host replaced by

* * Test

The shell host sends mail to the native root, and the 174host receives the mail.
