Postfix：禁用本地邮件传递

每当我给“root”发送电子邮件时，我希望它被转发到[电子邮件保护]（而不是本地交付）。

然而，我不断收到这样的信息：

Feb  9 17:41:54 botmaster postfix/smtp[29969]: B6E0B808F5: to=<[email protected]>, relay=none, delay=0.01, delays=0.01/0/0.01/0, dsn=5.4.6, status=bounced (mail for botmaster.corp.flatturtle.com loops back to myself)

这是我的main.cf：

# 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 (by FlatTurtle)
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.

myhostname = mx.flatturtle.com
#alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
local_transport = error:local delivery is disabled
mydestination = localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 172.27.0.0/18 85.12.6.130/32
#mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
relay_domains = /home/mx/postfix_transport
unknown_local_recipient_reject_code = 550 

smtpd_recipient_restrictions =
        permit_sasl_authenticated,
        permit_mynetworks,
        reject_unauth_destination,
        reject_unauth_pipelining,
        reject_rbl_client sbl-xbl.spamhaus.org,
        check_policy_service unix:private/postgrey,
        permit

有几种方法可以禁用本地传送，但似乎都不起作用（或者至少我一直收到该消息）。

挖掘 mx flatturtle.com：

flatturtle.com.     14679   IN  MX  30 mx.flatturtle.com.
flatturtle.com.     14679   IN  MX  10 mail.flatturtle.com.

挖掘 mx.flatturtle.com：

mx.flatturtle.com.          604800  IN  CNAME   mail2.rootspirit.com.
mail2.rootspirit.com.       21600   IN  CNAME   one.rootspirit.com.
one.rootspirit.com.         21600   IN  A       95.211.44.129

挖掘 mail.flatturtle.com：

mail.flatturtle.com.    444387  IN  CNAME   mail.rootspirit.com.
mail.rootspirit.com.    10265   IN  A       85.12.6.130

挖掘 flatturtle.com：

flatturtle.com.     14594   IN  A   85.12.6.130

挖掘 botmaster.corp.flatturtle.com：

botmaster.corp.flatturtle.com. 4680 IN  A   95.211.44.129

答案1

“邮件循环回到我自己”只有一个原因：postfix 正在向它负责的收件人域发送邮件，例如 RCPT TO：[电子邮件保护]，而 $myhostname 是 example.org 的 MX。

没有配置可以解决这个问题，因为它是你配置了什么。

将 root 的别名添加到 Postfix 框以外的某个地方，例如：

root:  [email protected]

答案2

Postfix 不允许将电子邮件发送到 SMTP 横幅中具有相同 myhostname 的目标 SMTP 服务器。那么您必须将当前的 myhostname 设置为 backup.example.org 或其他名称。

myhostname 是机器名，为了避免此问题，您可以将 MX 服务器名称设置为“dexter.example.org”，将备份服务器名称设置为“deedee.example.org”。RFC 1178 规定“使用主题名称”。

答案3

我发现了一种解决方法，即在名称服务器上创建一个新域名：“botmaster.corp.flatturtle.com”。

MX 记录指向另一个 SMTP 服务器。

因此邮件根（添加了@botmaster.corp.flatturtle.com 域）被转发并正确传递。
