我希望非本地电子邮件通过我的个人Google帐户和本地电子邮件转发给当地用户。 我的configuration是：/ etc / postfix / transport
* smtp:[smtp.gmail.com]:587 和/etc/postfix/main.cf
[root@media postfix]# cat main.cf # This file contains only the parameters changed from a default install # see /etc/postfix/main.cf.dist for a commented, fuller version of this file. transport_maps = hash:/etc/postfix/transport smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_mechanism_filter = plain, login smtp_sasl_security_options = noanonymous smtp_use_tls = yes
/等/后缀/ sasl_passwd：
[smtp.google.com]:587 [email protected]:mypass
而我运行后：
# postmap transport && postmap sasl_passwd systemctl restart postfix.service
所以，现在我的服务器尝试连接到gmail MX（没有成功，但不提供电子邮件本地

任何帮助，使其工作？
您必须在Postfix的SMTP客户端中启用TLS ，因为Google需要它。 这在消息Must issue a STARTTLS command由他们Must issue a STARTTLS command 。
在/etc/postfix/main.cf ，你需要这样的东西：
smtp_tls_policy_maps = hash:/etc/postfix/tls_policy
然后在/etc/postfix/tls_policy ：
[smtp.gmail.com]:587 encrypt
tls_policy的左侧必须与main.cf的relayhost条目完全相同。
请记住，在创build或根据需要更改后，在/etc/postfix/tls_policy上运行/etc/postfix/tls_policy 。
你可以在Postfix的TLS文档中find更多的细节。
请参阅这些链接
这是我使用的过程：
sudo apt-get install postfix.
如果询问您安装了哪种邮件服务器，请select无configuration（第一个选项）
sudo nano /etc/postfix/main.cf
并将其粘贴
# See /usr/share/postfix/main.cf.dist for a commented, more complete version # Debian specific: Specifying a file name will cause the first # line of that file to be used as the name. The Debian default # is /etc/mailname. #myorigin = /etc/mailname # listen on localhost only inet_interfaces = 127.0.0.1 smtpd_banner = $myhostname ESMTP $mail_name biff = no # appending .domain is the MUA's job. append_dot_mydomain = no #Uncomment the next line to generate "delayed mail" warnings #delay_warning_time = 4h relayhost = [smtp.gmail.com]:587 smtp_use_tls = yes smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous
保存文件，现在我们用用户名和密码创build文件
sudo nano /etc/postfix/sasl_passwd
并粘贴在下面做出所需的replace
[smtp.gmail.com]:587 [email protected]:password
保存它，并在命令提示符下
sudo postmap /etc/postfix/sasl_passwd
然后
chmod 600 /etc/postfix/sasl_passwd /etc/postfix/sasl_passwd.db
最后，
sudo service postfix restart
请注意，一旦您成功testing了电子邮件系统，您可以在sasl_passwd中删除/模糊密码。
用你的应用程序进行testing。 如果遇到麻烦，请检查/var/log/mail.log您可以通过apt-get install mail-utils来安装邮件程序。 你可以再testing一下
echo “this is a test” | mailx -s “This is the subject” [email protected]
最后
跑
newaliases
制作一个/etc/aliases.db文件。 如果你不这样会logging很多关于它的错误到/var/log/mail.err如果你得到SASL错误（postfix）检查主机名在/ etc / hosts和/ etc / hostname如果postfix抱怨没有能够中继给定的主机/ IP地址（后缀）添加到/etc/postfix/main.cf
mynetworks = 10.0.0.0/8
这将允许任何拥有10.0.0.0地址的人连接，显然你应该尽可能地减less这种情况，无论是通过限制networking，还是使用任何防火墙或安全策略
首先，请确保首先检查Google的身份validation方法：
https://www.google.com/settings/security/lesssecureapps
如果该页面不适用于您的帐户，则域pipe理员将为所有用户禁用此设置（默认）。
当您在google admin的中继SMTP中将您的IP /范围列入白名单时，您可以使用此设置发送电子邮件
relayhost = [smtp-relay.gmail.com]:587 smtp_use_tls = yes smtp_tls_loglevel=1 smtp_tls_security_level=encrypt smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = noanonymous smtp_sasl_mechanism_filter = login, plain smtp_tls_CApath = /etc/ssl/certs smtp_sasl_tls_security_options = noanonymous
但是，当Allow less secure apps: OFF我总是得到这些消息：
(SASL authentication failed; server smtp-relay.gmail.com[173.194.204.28] said: 534-5.7.14 ... Please log in via your web browser and?534-5.7.14 then try again.?534-5.7.14 Learn more at?534 5.7.14 https://support.google.com/mail/answer/78754 g133sm1077601qkb.1 - gsmtp)
但消息仍然传递（这有点奇怪），虽然它需要更长的时间才能收到消息。
