我想阻止某些用户向 中的其他域发送邮件Exim4
。我尝试了以下配置,但没有起作用。
exim.conf
文件中完成的更改:
在主配置部分,启用acl_smtp_mail
控制如下:
acl_smtp_mail = acl_check_mail
然后,在 acl_check_rcpt ACL 配置部分中,创建了一条新规则:
accept condition = ${lookup{$sender_address}lsearch{/etc/exim/freezelist_sender_addresses}{1}{0}}
control = freeze/no_tell
我试过了,但是没有用。请给我一些配置建议。
答案1
您可以使用以下 acl
acl_smtp_rcpt = acl_check_rcpt
acl_check_rcpt:
deny
message = The $sender_address is prohibited to send mail to the $domain
senders = lsearch;/etc/exim/restricted_sender
domains = lsearch;/etc/exim/restricted_domains
/etc/exim/restricted_sender
[email protected]
/etc/exim/restricted_domains
gmail.com
测试
# swaks -s mail.example.net --to [email protected] --from [email protected]
=== Trying mail.example.net:25...
=== Connected to mail.example.net.
<- 220 mail.example.net, [xxx.xxx.114.28]
-> EHLO www.example.net
<- 250-mail.example.net Hello www.example.net [xxx.xxx.114.28]
<- 250-SIZE 52428800
<- 250-PIPELINING
<- 250-STARTTLS
<- 250 HELP
-> MAIL FROM:<[email protected]>
<- 250 OK
-> RCPT TO:<[email protected]>
<** 550 The [email protected] is prohobited to sent mail to the gmail.com
-> QUIT
<- 221 mail.example.net closing connection
=== Connection closed with remote host.
答案2
最终解决方案一步一步
- 创建文件 restricted_sender。示例:/etc/restricted_sender
- 编辑 exim.conf
在 acl_smtp_rcpt 的开头添加下一条规则:(或者您如何称呼它)
deny condition = ${lookup{$sender_address}nwildlsearch{/path/to/the/restricted_sender} {yes}} domains = !+local_domains
文件/path/to/the/restricted_sender
包含每行一封电子邮件:
[email protected]
[email protected]
