我已经使用配置模式安装了 Postfix：Internet SIte
我的文件/etc/postfix/main.cf如下：
# 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
smtpd_banner = $myhostname ESMTP $mail_name (Raspbian)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# See http://www.postfix.org/COMPATIBILITY_README.html -- default to 2 on
# fresh installs.
compatibility_level = 2
# TLS parameters
smtpd_tls_cert_file = /etc/ssl/private/postfix.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = webserver.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = smtp.gmail.com
relayhost =

#CERTIFICADO DKIM
milter_default_action = accept

smtpd_milters = inet:localhost:8891
non_smtpd_milters = inet:localhost:8891
mydestination我已经编辑了Gmail 的 SMTP 服务器的参数
mydestination = smtp.gmail.com
Postfix 工作正常，我向我的 Gmail 发送了一封电子邮件
mail [email protected]
Cc:
Subject: title
There are message works
以及我的 Gmail 垃圾邮件箱：
我要怎么做才能使该电子邮件不成为垃圾邮件？
PD：我遵循了这一点：https://blog.openalfa.com/como-evitar-que-los-emails-enviados-por-postfix-sean-considerados-como-spam 但这不起作用。
我不希望将电子邮件发送到其他 SMTP 服务器并将其发送到目的地。
如何将邮箱地址更改[email protected]为其他地址？谢谢

总的来说，这与 Ubuntu 无关，但我决定写一个简短的答案。首先，server.com问题中的域名必须是注册域名。然后您至少有以下选择：
选项A）设置优先权和撤销您的域名的记录。这应该通过您的 DNS 提供商的控制面板完成。
选项B）你可以设置 smtp 中继第三方服务器（如sendgrid.com或者www.mailjet.com) 将为您发送电子邮件。
