Any news on this front?
I started special trapping on messages with base 64 encoding ONLY in
text/html mime segments late on 9/5. In slightly more than 2,000 total
messages since then there has been one such message. It was spam.
Why the message was encoded in base64 is just a mystery to me. The
message failed most
Hi Scott,
I am starting to see alot of these encoded emails (since I cant stop them),
here are a few more encoded spam samples.
So far it looks like something similar to this appears in each encoded
message.
Content-Type: text/html;
Content-Transfer-Encoding: base64
It would seem easy to catch
If anybody can produce legit reasons for sending mail this way please let
Scott know
That's exactly what I'm looking for.
I do have enough samples of the spam to work with; it's just a matter now
of finding out if there is legitimate mail that is being sent this way.

Well I don't know what legit means exactly but I can tell you there
are quite a few messages that come through our server that are base64
encoded or that contain base64 segments that are not SPAM.
base64 is used for virtually all types of attachments (.jpg, .exe, etc.),
so it will be common in

RSP I can't think of a single legitimate reason for a mail client to encode
Well again I don't see where it would be illegal to use any kind of
encoding available for any message.
I am very sure it is not illegal.
But if a spam test can catch a reasonable amount of spam, and in theory
