/etc/clamd.conf 里有一个 "ScanPDF yes"，将它改为 no，并重启 clamav 试试。

如果还不行，就在 /etc/amavisd.conf 的顶部找到这句：

# @bypass_virus_checks_maps = (1);

将这一行的注释去掉，重启 amavisd，就不会再调用 ClamAV 了。

ScanPDF yes 这个我是最早就改成 no 了

关闭ClamAV是最后的办法了 sad

还是不行啊，amavisd.conf修改好以后已经重启服务器了，还是被过滤

$policy_bank{'MYNETS'} = {}
$policy_bank{'ORIGINATING'} = {}
$policy_bank{'MYUSERS'} = {} # 这一个在旧版本 iredmail 里没有，所以可以不用

在上面几个设置的大括号内，加入这么一句：

bypass_virus_checks_maps => [1],

重启 amavisd 后，所有你的用户发出去的邮件都不会做病毒检测，包括 PDF 和其它各种类型的文件，但对于收到的外部邮件仍然会做检测。

在公司里内部转发出现以上的pdf病毒，但是这个pdf文件是理光扫描仪直接出来的pdf文件，不可能有病毒
能否关闭clamav pdf文件扫描呢？

公司里常用pdf文件，影响很大，谢谢
