Description (partial)

Using the <cmdbold>match MIME filetype regex<nocmdbold> command to drop SMTP connections based upon a MIME filetype may also drop connections based on the content of the files.

This occurs when an extended ESMTP inspection map is configured to look for specific MIME Filetypes to block.
