Rejecting bad attachments best practice?

  • 772

When configuring a mail server, what is the best practice for rejecting an inbound internet email with an executable type I'd like to disallow? Easiest option is an NDR/DSN, but I'd think that could put one at risk to create backscatter.

email smtp postfix sendmail email-server

  1. When the mail server is sendmail, I install MIMEDefang use it to enforce attachment policy.
