Postfix和Amavis – 使用UNIX Soket进行通信

我目前使用Postfix,Dovecot,Amavis和Spamassassin进行复杂的邮件服务器设置.

一切正常,但我想改进Postfix-Amavis-Communication.目前,postfix将所有邮件发送到localhost：10024,这是amavis服务.在所有检查之后,修改后的版本被发送回localhost：10025,这是一个用于接收amavis邮件的后缀服务.

我的想法：UNIX SOCKETS(由于安全原因;不重要的原因)

所以我配置amavis在/run/amavis/amavis.socket中生成一个unix套接字.

我改变了这个：

amavis-forward:[127.0.0.1]:10024` to `amavis-forward:unix:/run/amavis/amavis.sock

但后来我得到了这个错误：

Jan  5 13:55:23 server postfix/smtp[1447]: fatal: unknown service: /run/amavis/amavis.sock/tcp
Jan  5 13:55:24 server postfix/qmgr[1254]: warning: private/amavis-forward socket: malformed response
Jan  5 13:55:24 server postfix/qmgr[1254]: warning: transport amavis-forward failure -- see a prevIoUs warning/fatal/panic logfile record for the problem description

因此邮件状态设置为status = deferred(未知邮件传输错误).

master.cf：

...
 # Amavis
 amavis-forward   unix    -       -       -       -       2       smtp
    -o smtp_tls_security_level=none
    -o smtp_data_done_timeout=1200
    -o smtp_send_xforward_command=yes
    -o disable_dns_lookups=yes
    -o max_use=20
 ...

结束：10024一切正常.我该如何解决？

免责声明：这是半答案,因为我可以在后缀时使用套接字 – > amavis但是我不能在amavis时使用它 – >后缀.请参阅本答案末尾的解释.

要使用套接字,您应该使用LMTP而不是SMTP将postfix中的电子邮件发送到amavis.

正如NickW上面所说,你需要将amavis套接字放在Postfix队列目录中.在这个答案中我假设postfix队列目录是/ var / spool / postfix /.

创建目录以保存amavis套接字

mkdir /var/spool/postfix/amavis/
chmod 750 /var/spool/postfix/amavis/
chown amavis:amavis /var/spool/postfix/amavis/

在amavis组中添加postfix用户

usermod -G amavis postfix

在amavisd.conf中配置

# for socket,it should reside in /var/spool/postfix
$unix_socketname = "/var/spool/postfix/amavis/amavisd.sock";

# set permission so amavis group can access this socket
$unix_socket_mode = 0660;

# Replace $interface_policy{'SOCK'} = 'AM.PDP';

$interface_policy{'SOCK'} = 'mysock';
$policy_bank{'mysock'} = {
   protocol => 'LMTP',auth_required_release => 0,# don't require secret-id for release
};

Postfix main.cf

content_filter = amavis-forward:unix:amavis/amavisd.sock

Postfix master.cf

# Amavis
amavis-forward   unix    -       -       -       -       2       lmtp
    -o lmtp_data_done_timeout=1200
    -o lmtp_send_xforward_command=yes
    -o disable_dns_lookups=yes
    -o max_use=20

结果

对于amavis – >后缀传输,由参数forward_method控制.除了使用smtp,我不熟悉这个配置.在example in this page中,此参数支持的显然协议是pipe,smtp和bsmtp.此外,基于postfix architecture,postfix仅接受来自smtpd,qmqmd或sendmail的电子邮件.
