Hello,


I am receiving emails with virus as an attachment, to analyze the mail I use clamav, but I want to avoid that the mail is analyzed.


Is it possible to block the SMTP connection if the host does not have a reverse?


here an example:


FROM: "Steven_Johnson-walsh@???" - X-Mailer = "" - Subject = Scan

H=([103.58.115.239]) [103.58.115.239] F=<Steven_Johnson-walsh@???> rejected after DATA: This message contains a virus (Sanesecurity.Foxhole.7z_vbs.UNOFFICIAL).


host 103.58.115.239
Host 239.115.58.103.in-addr.arpa. not found: 3(NXDOMAIN)
