我在 AWS 上设置了一个 Postfix/Dovecot 邮件服务器。我已实施自签名 TLS 授权，从外部 TBird 客户端连接到它并尝试发送/接收电子邮件。TBird 能够检测到我的服务器并且可以正常接收电子邮件，但我尝试发送时出现错误：
NOQUEUE: reject: RCPT from <<LOCAL BOX>>: 553
5.7.1 <<[email protected]>>: Sender address rejected: not owned by user username; from=<<[email protected]>>
to=<<[email protected]>> proto=ESMTP helo=<<[192.168.1.148]>>
错误发生后，我可以保存草稿。
我可以手动将 openssl 放入 587 并完成身份验证，但是当我使用 rcpt 命令时，出现相同的错误。
这是我第一次发帖，如果需要提供更多信息，请告诉我：
后配置-n
alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 1 home_mailbox = Maildir/ html_directory = no inet_interfaces = all inet_protocols = all mail_owner = postfix mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain mydomain = mydomain.tld myhostname = mail.mydomain.tld mynetworks = 168.100.189.0/28, 127.0.0.0/8 myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES relay_domains = sample_directory = /usr/share/doc/postfix-2.6.6/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_helo_name = $myhostname smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_path = private/auth smtpd_sasl_security_options = noanonymous smtpd_sasl_type = dovecot smtpd_sender_restrictions = permit_mynetworks, permit_sasl_authenticated smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/mail.anythingbox.org.crt smtpd_tls_key_file = /etc/postfix/ssl/mail.anythingbox.org.key smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550
对 main.cf 的更改
smtp_helo_name = $myhostname
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_sasl_type = dovecot
smtpd_sasl_path = private/auth
smtpd_sasl_security_options = noanonymous
smtpd_sender_restrictions =

smtpd_recipient_restrictions =

smtpd_tls_key_file = /etc/postfix/ssl/mail.mydomain.tld.key
smtpd_tls_cert_file = /etc/postfix/ssl/mail.mydomain.tld.crt
smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem
tls_random_source = dev:/dev/urandom
我花了一天时间浏览每一个谷歌搜索结果，但似乎无法找到任何方法来解决这个问题......任何帮助都非常感谢。
答案1
您可以在 postfix 中使用 smtpd_sender_login_maps。这是一个
可选查找表，其中包含发件人（MAIL FROM）地址的 SASL 登录名
在 /etc/postfix/main.cf 中
smtpd_sender_login_maps = hash:/etc/postfix/smtpd_sender_login_maps
包含内容
[email protected] username
或者如果你使用虚拟邮箱，你可以映射到它们
smtpd_sender_login_maps = $virtual_mailbox_maps
virtual_mailbox_maps = hash:/etc/postfix/virtual-mailbox-users
答案2
对我来说reject_sender_login_mismatch
我将其从smtpd_sender_restrictions价值中删除
