後綴：由於 ESMTP 拒絕中繼訪問

我已經設置了 mailman 和 postfix，但是郵件沒有通過郵件列表發送到。Postfix 拒絕它，因為收件人域沒有添加到postfix_domains.

這是我的main.cf：

recipient_delimiter = +
unknown_local_recipient_reject_code = 500
owner_request_special = no
myhostname = develop.product.company.com
mynetworks = 10.92.5.5/16

# Increase deferred mail delivery frequency
queue_run_delay = 60s
minimal_backoff_time = 30s
maximal_backoff_time = 120s
# BEGIN ANSIBLE MANAGED BLOCK
recipient_delimiter = +
unknown_local_recipient_reject_code = 500
owner_request_special = no
transport_maps =  hash://opt/mailman/var/data/postfix_lmtp
local_recipient_maps =  hash://opt/mailman/var/data/postfix_lmtp
relay_domains = hash://opt/mailman/var/data/postfix_domains
# END ANSIBLE MANAGED BLOCK

Mailman 中的郵件列表已在domain1.com和中創建domain2.com，文件postfix_domains如下所示：

# AUTOMATICALLY GENERATED BY MAILMAN ON 2017-02-09 02:43:51
#
# This file is generated by Mailman, and is kept in sync with the binary hash
# file.  YOU SHOULD NOT MANUALLY EDIT THIS FILE unless you know what you're
# doing, and can keep the two files properly in sync.  If you screw it up,
# you're on your own.

domain1.com domain1.com
domain2.com domain2.com

當我嘗試向該郵件列表（其中persona@company.com是訂閱者）發送郵件時，我收到以下錯誤：

postfix/smtpd[8110]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 454 4.7.1 <persona@company.com>: Relay access denied; from=<testing-mailinglist-bounces@domain1.com> to=<persona@company.com> proto=ESMTP helo=<ip-10-92-34-5.ap-northeast-1.compute.internal>

我執行以下命令postconf -d | grep "smtpd_r"以獲得以下結果：

postscreen_reject_footer = $smtpd_reject_footer
smtpd_recipient_limit = 1000
smtpd_recipient_overshoot_limit = 1000
smtpd_recipient_restrictions =
smtpd_reject_footer =
smtpd_reject_unlisted_recipient = yes
smtpd_reject_unlisted_sender = no
smtpd_relay_restrictions = permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination
smtpd_restriction_classes =

我已經閱讀了在這個論壇上提出的類似問題，但我沒有找到這樣一個確切的問題。有人可以幫我解決這個問題嗎？

謝謝！

授權網路使用main.cf中的**mynetworks配置參數定義

當您從 localhost 發送電子郵件時：

postfix/smtpd[8110]: NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 454 4.7.1 <persona@company.com>: Relay access denied; from=<testing-mailinglist-bounces@domain1.com> to=<persona@company.com> proto=ESMTP helo=<ip-10-92-34-5.ap-northeast-1.compute.internal>

您必須允許 postfix 轉發來自本地主機的電子郵件。編輯main.cf添加：

mynetworks = 127.0.0.0/8
