配置 Postfix 以将邮件转发到其他邮件地址（例如 gmail）？

Question

我已将 Ubuntu 服务器上的 Postfix 配置为 send/receive 邮件。

虽然发送工作正常，但接收工作不正常。我想将所有收到的邮件转发到我的 gmail 帐户。

我的/etc/postfix/mail.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 (Ubuntu)
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

# TLS parameters
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.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

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = mail.compzzz.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
virtual_alias_domains = compzzz.com
virtual_alias_maps = hash:/etc/postfix/virtual
myorigin = /etc/mailname
mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
inet_protocols = all

我的 /etc/postfix/virtual 是：

@compzzz.com ramabc@gmail.com

我发送到 abc@compzzz.com 的任何邮件，我都会收到一封包含未知用户错误的投递失败电子邮件。

我是不是哪里出错了？

Answer 1

不幸的是没有得到技术人员的任何帮助，这迫使我自己经历了 postfix documentation。

只需注释声明 mydestination 的行即可。

即替换行

mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com

和

#mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com

要将电子邮件转发到另一个地址（除了您的服务器），不需要 mydestination 参数，只需要 virtual_alias_domains 和 virtual_alias_maps。

配置 Postfix 以将邮件转发到其他邮件地址（例如 gmail）？

Configure Postfix to forward mails to other mail addresses (ex gmail)?
