CentOS 6.4 上针对 Gmail 的 Postfix SMTP 中继服务器

我目前正在尝试在 CentOS 6.4 机器上使用 Postfix 设置到 Gmail 的 SMTP 中继服务器，以便我可以从我的 PHP 脚本发送电子邮件。

我跟着这教程，但我尝试执行时收到此错误输出

发送邮件[电子邮件保护]

输出：

tail -f /var/log/maillog

这是我的主配置文件配置，我尝试了许多不同的选项，但似乎没有任何效果：

alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
inet_interfaces = localhost
inet_protocols = ipv4
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost
myhostname = host.local.domain
myorigin = $myhostname
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
relayhost = [smtp.gmail.com]:587
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
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_sasl_type = cyrus
smtp_tls_CAfile = /etc/ssl/certs/ca-bundle.crt
smtp_use_tls = yes
smtpd_sasl_path = smtpd
unknown_local_recipient_reject_code = 550

在里面在 /etc/postfix/sasl_passwd 文件中文件（sasl_passwd 和 sasl_passwd.db）我得到以下内容（删除了真实密码，并将其替换为“密码”）：

[smtp.google.com]:587[电子邮件保护]：密码

要创建 sasl_passwd.db 文件，我通过运行以下命令来完成：

postmap 哈希：/etc/postfix/sasl_passwd

有人知道为什么我似乎无法从服务器发送电子邮件吗？

亲切问候 Alex

# telnet smtp.gmail.com 587
Trying 173.194.70.108...
Connected to smtp.gmail.com.
Escape character is '^]'.
220 mx.google.com ESMTP h52sm28987766eez.3 - gsmtp

没有可用的身份验证。您必须使用启动TLS在端口 25/587 上或在端口 465 上使用 SSL/TLS

smtp_tls_policy_maps = hash:/etc/postfix/tls_policy
smtp_tls_security_level = secure
smtp_tls_mandatory_protocols = TLSv1
smtp_tls_mandatory_ciphers = high
smtp_tls_secure_cert_match = nexthop

在 /etc/postfix/tls_policy 中

gmail.com encrypt protocols=TLSv1 ciphers=high

在 /etc/postfix/sasl_passwd 文件中

[smtp.gmail.com]:587 [email protected]:password

在邮件日志中会有类似以下内容

# swaks -s 127.0.0.1 --helo localhost --to [email protected] --from [email protected]
