在postfix使用qq企业邮箱的smtp

在/etc/postfix/main.cf中添加如下信息

smtpd_tls_cert_file=/etc/ssl/certs/your.crt
smtpd_tls_key_file=/etc/ssl/private/your.key
smtpd_tls_CAfile=/etc/ssl/certs/your-chaint.crt

smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

relayhost = [smtp.exmail.qq.com]:587
smtp_sasl_auth_enable = yes
smtpd_tls_auth_only = no
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
#smtp_generic_maps = hash:/etc/postfix/generic

在/etc/postfix/创建文件sasl_passwd，填写如下内容

[smtp.exmail.qq.com]:587 EMAIL-ADDRESS:PASSWORD

然后通过如下命令生成hash库

postmap /etc/postfix/sasl_passwd

重启postfix

service postfix restart
