我正在尝试使用/etc/ postfix /main.cf中的以下内容配置postfix以使用中继主机:
relayhost = [mailtrap.io]:2525
smtp_sasl_auth_enable = yes
smtp_sasl_mechanism_filter = plain
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd通过telnet localhost 25发送电子邮件后,后缀日志显示:

该问题是由于默认的postfix SMTP安全选项不允许有未加密的密码造成的。

在这种情况下,正确的配置是:
relayhost = [mailtrap.io]:2525
smtp_sasl_auth_enable = yes
smtp_sasl_mechanism_filter = plain
smtp_sasl_security_options = noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd发布于 2012-12-27 01:26:34
在配置文件中,您可能需要设置smtp_use_tls = yes (请参阅http://mhawthorne.net/posts/postfix-configuring-gmail-as-relay.html中的配置)
除了以上内容之外,我还必须确保安装了libsasl2-modules:
运行以下命令:
apt-get install libsasl2-modules
/etc/init.d/postfix重启
