Postfix+mysql
1. Configure mysql
Before the experiment, the production should use the database and tables.
Add database users and authorize them
* 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
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/
