Hello people,
As I posted here earlier, I am working on a spam filter setup that includes
(next to filtering) whitelisting and blacklisting. Whitelisting systems are
prone to several problems, one of those is deadlock. And also, since
headers can be easily forged, there is need for some special headers to
recognize messages that are created by mail filters (mainly to make sure
these are dropped in certain circumstances).
There are several good reasons to have these kind of headers.
I'd like therefore to propose that the following header will be part of any
MFA (Mail Filtering Setup):
X-MFA-Request-By:
(Or any other appropriate name). This header will be followed by the MFA
ID. Filters may use this to filter out messages or to decide not to send
delivery failures or etc. etc. It is of course not meant as a authentication
device as these headers may be easily forged.
I want to propose too that any MFA headers will start with X-MFA-.
The system, btw, will be available soon (as soon as I finish the documentation).
