Do I need to check both Content-(Type|Disposition) ?
from what I can see, an attachment is always identified by its filename,
as in:
Content-Disposition: attachment;
filename="bla_bla.docx"; size=168097;
creation-date="Tue, 02 Dec 2014 13:26:29 GMT";
modification-date="Tue, 02 Dec 2014 13:26:29 GMT"
If I wanted to reject all doc|docx attachments, can I use this simpler
rule ?
/^Content-Disposition: .*filename=".*\.(doc|docx)"/ REJECT Attachment
rejected
or will some attachments slip through ?
