拒绝使用 Postfix 向特定收件人发送电子邮件

dam*_*anb 7 email postfix blacklist

所以,现在我正在尝试通过smtpd_recipient_restrictions.

我遇到的问题是我的测试电子邮件在我期望它们被系统拒绝时正在发送。

这是 /etc/postfix/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 (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_recipient_restrictions =
        reject_unknown_recipient_domain,
        reject_unauth_destination,
        check_recipient_access hash:/etc/postfix/recipient_block

myhostname = hostname.domain.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = hostname.domain.com, hostname.domain.com, , localhost
relayhost =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = procmail -a "$EXTENSION"
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all

我的/etc/postfix/recipient_block(这是后来通过 postmap 运行的)

personalemail@anotheroneofmydomains.com REJECT

然后,我像这样发送测试电子邮件:

$ echo test | mail -s "test email, please ignore" personalemail@anotheroneofmydomains.com

Postfix 已重新加载其 conf,已重新启动几次以尝试排除故障,但均无济于事。

尾随/var/log/mail.log文件的块读取如下:

......所以,我很难过。我不明白为什么电子邮件没有被拒绝。

问题是邮件是通过pickup服务(通过 sendmail 接口)发送的,因此它是“传出”邮件。对于外发邮件,smtpd_*_restrictions不适用。这些限制仅适用于通过 SMTP 发送的“传入”邮件。

编辑 Victor Duchovni(Postfix 维护者)甚至提供了一个解决方案:http ://marc.info/?l=postfix-users&m=120155612332393&w=1
