我有一个后缀安装,并通过谷歌应用程序设置中继,但是当我发送邮件到后缀它使用我在main.cf中指定的一个帐户中继到谷歌应用程序。
有没有办法更dynamic地做到这一点。 理想情况下,用户在发送邮件时会使用postfix进行身份validation,而postfix会使用该用户名和密码对gmail进行身份validation。 这是可能的还是下一个最好的解决scheme?
提前致谢
最后,你基本上必须同步两个密码文件,或者更多的types可能可以使用一个MySQL表来validation客户端与后缀,然后得到后缀查询同一个表使用gmail身份validation。 另一个想法可能是find一个对gmail进行身份validation的PAM模块。
无论如何,我用这个指南
设置每个用户帐户中继:
# smtp_use_tls=yes smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_sasl_tls_security_options = noanonymous
smtp.gmail.com [email protected]:PASSWORD
然后我在postfix上设置了sasldb auth,以便客户端必须对postfix进行身份validation。 Postfix查询sasldb2文件。
缺点是,如果您更改gmail密码并希望保持一切同步,则必须更新/ etc / postfix / sasl_passwd并更新/ etc / sasl2db。
这是我的main.cf
