We have a problem with our CPANEL email. We are getting Bounceback error 552 when forwarding emails with attachment. The bounce message looks like this: This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: recipient1@sampledomain.com[/EMAIL] This message has been rejected because it has a potentially executable attachment "samplefile.pdf" This form of attachment has been used by recent viruses or other malware. If you meant to send this file then please package it up as a zip file and resend it.
What's weird is this only happens when forwarding emails with attachments in other formats (like jpg, pdf, eml, msg etc.)... But those with ZIP type of attachment. The email goes through.

  Hello :) This is by design per the Exim system filter. You can modify the filter if you prefer, using the instructions at: How to Customize the Exim System Filter File - cPanel Knowledge Base - cPanel Documentation Thank you.
