Question

我有一个带有sasl auth的工作后缀服务器，只要我使用属于我用于sasl_auth的用户的from-field中的电子邮件地址，它就可以正常工作。但是，如果我想从不同于sasl_username中使用的电子邮件发送，那么我在日志中会收到以下错误：

Client host rejected: Server configuration error (in reply to RCPT TO command))

我想要的是让Postfix允许来自rcpt to field中任何地址的邮件，但仍然启用了auth机制。
我怎么能这样做？
输出我的postconf -n：

[root@mailout /]# postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
append_dot_mydomain = no
biff = no
compatibility_level = 2
home_mailbox = Maildir/
inet_interfaces = all
inet_protocols = ipv4
mailbox_size_limit = 0
mydestination = mailout.domain.com, mailout.domain.com, localhost.domain.com, , localhost
myhostname = mailout.domain.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 10.1.1.5
myorigin = /etc/mailname
readme_directory = no
recipient_delimiter = +
relayhost = 
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
smtpd_recipient_restrictions = permit_mynetworks permit_inet_interfaces permit_sasl_authenticated
smtpd_reject_unlisted_sender = no
smtpd_sasl_auth_enable = yes
smtpd_sender_restrictions =
smtpd_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtpd_tls_cert_file = /etc/ssl/certs/wildcard.crt
smtpd_tls_key_file = /etc/ssl/private/wildcard.key
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
smtputf8_autodetect_classes = sendmail, verify

Answer 1

您需要在smtpd_sender_restrictions或smtpd_relay_restrictions中允许使用sasl auth。

smtpd_sender_restrictions = permit_sasl_authenticated

可能需要更多特定限制，但是应该修复您的问题。
