总结：

我在使用 clamd 和 amavisd 时遇到问题，请参阅下面的错误消息，我在 CentOS 7.3 上运行电子邮件服务器.....amavisd 和 clamd 似乎运行良好，但每次在我从我的电子邮件服务器发送邮件之前，它们都会出现错误，如果我从 Gmail 向我的电子邮件服务器发送邮件，也会出现错误。

总结：

setsebool -P antivirus_can_scan_system 1
setsebool -P clamd_use_jit on

yum install clamav-scanner-systemd

cd /usr/lib/systemd/system
cp clamd\@scan.service clamd\@amavisd.service

systemctl start clamd@amavisd
systemctl enable clamd@amavisd
systemctl restart amavisd

长版本：

我猜你收到“没有这样的文件或目录”错误是因为套接字/var/run/clamd.amavisd/clamd.sock不存在，而这又是因为 clam 守护进程未安装或未运行并未在该套接字上监听。

要修复，请尝试

yum install clamav-scanner-systemd

...其中包括守护进程，clamd。

默认情况下，它附带的服务（包括）会尝试打开错误的配置文件，因为/usr/lib/systemd/system/[email protected]/usr/lib/systemd/system/[email protected]%i在服务中，它是实例名称的占位符。要使服务改用 amavis conf 文件，请将其复制到适当实例化的单元：

cd /usr/lib/systemd/system
cp clamd\@scan.service clamd\@amavisd.service

（看9.6.5. 使用实例化单元在RHEL 7 文档了解更多信息）

最后，尝试

systemctl start clamd@amavisd

并检查它现在是否正在运行，使用

systemctl status clamd@amavisd

最后启用它

systemctl enable clamd@amavisd

检查 的内容/var/run/clamd.amavisd，您现在应该发现clamd.sock存在。

为了更好的衡量，

systemctl restart amavisd

并仔细检查您的日志文件，确保一切正常。

如果不是，如果SELinux正在强制执行，您可能需要先运行以下命令，以使 ClamAV 和 freshclam 正常运行：

setsebool -P antivirus_can_scan_system 1
setsebool -P clamd_use_jit on

答案2

我在 Centos 7 上的 Plesk 上遇到了这个问题

问题，项目滞留在邮件队列中

日志包括status=deferred (delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused)

解决方案安装 Amavis（一种开源电子邮件内容过滤器）https://www.amavis.org

yum install amavisd-new 
systemctl enable amavisd && systemctl start amavisd
systemctl restart postfix

https://support.plesk.com/hc/en-us/articles/12376969376279-Unable-to-send-mail-deferred-delivery-temporarily-suspended-connect-to-127-0-0-1-127-0-0-1-10024-Connection-refused
