配置postfix和dovecot启用SSL。

[root@mail ~]# vi /etc/postfix/main.cf
# 添加如下到末尾。
smtpd_use_tls = yes
smtpd_tls_cert_file = /etc/pki/tls/certs/server.crt
smtpd_tls_key_file = /etc/pki/tls/certs/server.key
smtpd_tls_session_cache_database = btree:/etc/postfix/smtpd_scache

[root@mail ~]# vi /etc/postfix/master.cf
# 第17-18行: 去掉注释
smtps       inet   n       -       n       -       -       smtpd
  -o smtpd_tls_wrappermode=yes

[root@mail ~]# vi /etc/dovecot/conf.d/10-ssl.conf
# 第6行: 
ssl = yes
# 第12,13行:
ssl_cert = </etc/pki/tls/certs/server.crt
ssl_key = </etc/pki/tls/certs/server.key

配置完成后，重新启动postfix和dovecot。
