Antigen is blocking Winzip encrypted files RRS feed

  • Question

  • Running Exchange 2003 SP2 on Windows 2003 Server. We have Antigen/Forefront running on these Exchange servers.

    A couple of our users have started wanting to send Winzip password encrypted attachments to external recipients, however they seem to be blocked by Antigen for the reason that they have an "illegal MIME header".

    Is there any explanation for this? Is this because Antigen cannot read the file?
