我正在尝试将 Google 设置为邮件中继，但遇到了一些麻烦。
我收到一个错误
550-5.1.1 The email account that you tried to reach does not exist
我在 pfSense 中的自定义主页如下所示：
relayhost = [smtp-relay.gmail.com]:587
#Defining domain and hostname- Test
myhostname = vpn.example.com
mydomain = example.com
myorigin = example.com
# Add TLS
#
# SMTPD
#
smtpd_tls_cert_file = /etc/postfix/cert.crt
smtpd_tls_key_file = /etc/postfix/cert.key
smtpd_tls_CAfile = /etc/ssl/cert.pem
smtpd_tls_security_level = may
# SMTP Client
smtp_tls_security_level = may
smtp_tls_CAfile = /etc/ssl/cert.pem
# SSL-Certificate - Generate logfile entries
#
smtpd_tls_received_header = yes
smtp_tls_loglevel = 1
smtpd_tls_loglevel = 1
当我尝试从 pfSense 服务器发送邮件时，我的日志文件显示以下内容：
Aug 11 14:59:07 <host> postfix/smtp[49764]: > smtp-relay.gmail.com[173.194.220.28]:587: MAIL FROM:<> SIZE=3532

我不明白为什么 smtp 标头 MAIL FROM: <> 为空，以及为什么 RCPT 说[电子邮件保护]而不是我尝试发送邮件的那个，就像[电子邮件保护]。

答案1
您正在覆盖local_recipient_maps并取消设置它：
local_recipient_maps =
默认值为：
local_recipient_maps = proxy:unix:passwd.byname $alias_maps
第一部分管理本地用户，见：
$ sudo postmap -q root proxy:unix:passwd.byname
root:x:0:0:root:/root:/bin/bash
删除上面引用的行以允许 root 本地用户接收者或将 root 添加到虚拟用户（包括虚拟域等）
