![Postfix check_recipient_mx_access 不起作用](https://linux22.com/image/777698/Postfix%20check_recipient_mx_access%20%E4%B8%8D%E8%B5%B7%E4%BD%9C%E7%94%A8.png)
我已在 Postfix 中配置了 check_recipient_mx_access 选项,以便拒绝发送拼写错误的域名的电子邮件。我们有一个发送航班确认的系统,很多时候用户会写错联系电子邮件帐户。
该文件指出以下内容
check_recipient_mx_access type:table
Search the specified access(5) database for the MX hosts for the
RCPT TO domain, and execute the corresponding action. If no MX
record is found, look up A or AAAA records, just like the Postfix
SMTP client would. Note: a result of "OK" is not allowed for safety
reasons. Instead, use DUNNO in order to exclude specific hosts from
denylists. This feature is available in Postfix 2.1 and later.
我的配置如下:
main.cf
smtpd_recipient_restrictions = reject_invalid_hostname,
reject_unauth_pipelining,
permit_mynetworks,
permit_sasl_authenticated,
reject_unauth_destination,
check_client_access hash:/etc/postfix/rbl_override,
check_recipient_mx_access hash:/etc/postfix/bogus_mx,
下列规则被添加到文件bogus_mx中:
54.159.98.68 REJECT
当我尝试通过 telnet 发送电子邮件时,它并没有被拒绝:
root@mailserver:~# telnet localhost 25
Trying ::1...
Connected to localhost.
