为 Amavis 禁用 ClamAV

Question

我有一个 Postfix 邮件服务器，使用 Amavis 和 Spamassassin 来检查不需要的电子邮件。我已经删除了 ClamAV，因为它基本上会在每次有人收到电子邮件时冻结整个服务器，并且服务器端病毒扫描对我的用例来说似乎并不重要。

Spamassassin 仍然由 Amavis 触发，我想保持这种状态。
基本上我想要的是 Amavis 停止尝试为每封电子邮件触发病毒扫描。

我已经尝试在 中注释掉几个选项/etc/amavis/conf.d/15-av_scanners，但看起来如果我注释掉某些内容，它只会使用默认配置，这与最初的配置相同。

# ['ClamAV-clamd',
#   \&ask_daemon, ["CONTSCAN {}\n", "/var/run/clamav/clamd.ctl"],
#   qr/\bOK$/m, qr/\bFOUND$/m,
#   qr/^.*?: (?!Infected Archive)(.*) FOUND$/m ],

如您所见，这是注释掉的。因此，它只是寻找备份扫描程序，而这些扫描程序都不存在。但是，这仍然会向日志发送带有上述消息的垃圾邮件并延迟邮件传递。
注释掉备份扫描器对此完全没有影响（事实上，当注释掉它时，它仍然会触发以前存在的东西）。

如何将 Amavis 配置为仍然使用 Spamassassin，但停止尝试扫描每封电子邮件中的病毒？

由于您想完全禁用病毒检查，最简单的方法是@bypass_virus_checks_maps在 Amavis 配置文件（amavis.conf或conf.d/50-user）中找到该行并将其更改为：

bypass_virus_checks_maps => [1];
