The following mainly brings you postfix+mysql send mail service, I hope these contents can bring you practical use, this is also my main purpose of editing postfix+mysql send mail service this article. All right, don't talk too much nonsense, let's just read the following.

1. Configure mysql

* before the experiment, make use of database and table.

* add and authorize database users

* vim / etc/postfix/mailuser.cf # # query user name

1 host = localhost # # Database host

2 user = postuser # # Login database user

3 password = 123 # # login password

4 dbname = email # # name of the postfix query library

5 table = emailuser # # name of the postfix query table

6 select_field = username # # fields for postfix query

7 where_field = username # # conditions for postfix query

* vim / etc/postfix/maildomain.cf # # Domain name query

1 host = localhost

2 user = postuser

3 password = 123

4 dbname = email

5 table = emailuser

6 select_field = domain

7 where_field = domain

* vim / etc/postfix/mailbox.cf # # query mailbox location

1 host = localhost

2 user = postuser

3 password = 123

4 dbname = email

5 table = emailuser

6 select_field = maildir

7 where_field = username

test

two。 Configure postfix

* groupadd-g 666 vmail # # add a user group and specify a gid of 666

Useradd-s / sbin/nologin-u 666 vmail-g 666 # # add users and specify uid and gid as 666

* postconf-e "virtual_mailbox_base = / home/vmail" # # set the virtual user mail directory

Postconf-e "virtual_uid_maps = static:666" # # specify the virtual user to create the file uid

Postconf-e "virtual_gid_maps = static:666" # # specify the virtual user to create the file gid

Postconf-e "virtual_alias_maps = mysql:/etc/postfix/mailuser.cf" # # specify MySQL lookup host

Postconf-e "virtual_mailbox_domains = mysql:/etc/postfix/maildomain.cf" # # specify the MySQL lookup domain name

Postconf-e "virtual_mailbox_maps = mysql:/etc/postfix/mailbox.cf" # # specify MySQL to find mailboxes

* systemctl restart postfix # # restart the postfix service

test

The email sent to linux@linux.com is found in / home/vmail/linux/new/
