同　http://yves2005.pixnet.net/blog/post/64733578　所講的，但 postfix 的　main.cf要修改如下：

a. vi main.cf

smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_auth_enable = yes
smtpd_recipient_restrictions =  permit_mynetworks,
    permit_sasl_authenticated,
    reject_unauth_destination,
    reject_non_fqdn_sender,
    reject_unknown_sender_domain,
    reject_rbl_client cbl.abuseat.org,
    reject_rbl_client bl.spamcop.net,
    reject_rbl_client sbl-xbl.spamhaus.org
broken_sasl_auth_clients = yes
smtpd_sasl_security_options = noanonymous
mailbox_size_limit = 512000000
message_size_limit = 10240000
 

b. install dovecot

如要走明碼收信的話，修改如下：

vi  /usr/local/etc/dovecot/conf.d/10-ssl.conf

ssl = no

 vi /usr/local/etc/dovecot/conf.d/10-auth.conf

disable_plaintext_auth = no

ps: 啟用明碼傳輸，不然使用outlook收信會出現錯誤訊息.

c. check sockstat

root@lab2[/usr/local/etc/postfix]> sockstat -4l
USER     COMMAND    PID   FD PROTO  LOCAL ADDRESS         FOREIGN ADDRESS
