attribute vaues with "3D" prefix?

[Steven]

Hello all,
I often see html attribute values in html (spam) email preceded with
'3D'. e.g.: align=3Dleft. I'm just wondering what this is. Some kind of
special mail flavor of html, some kind of propietary code or what?

Quoted-Printable encoding. Look it up (e.g. on google).
A relic from the days when mail was 7-bit.

Ah, I see, it is Quoted Printable encoding for the equal sign...
Is there a legitimate reason to use it still or is it a givaway that it
is junk mail? If so that would inprove my spam filter...

Quoted-printable encoding, sometimes referred to as quoted-unreadable.

By whom?

It's certainly deprecated by me. I remember lots of instances where
it made things harder to read, and none where it helped.

Whether it once served a purpose, or still has some legitimate
purpose unknown to me, I couldn't say.

The standards for e-mail format (RFC 2822) still forbid the use of any
non-US-ASCII characters without encoding, so to stay compliant with the
standards you do need to use quoted-printable (or the completely
unreadable base64) to encode anything that contains characters out of
the ASCII range.

A properly standards-compliant MIME-supporting mail reader will decode
the quoted-printable text, so you shouldn't actually see the "=3D" parts
unless you view the raw message source.

Quoted-printable encoding, sometimes referred to as quoted-unreadable.

Only unreadable if your mail client doesn't support it, or if you view
the raw message source instead of the properly rendered message.

Though I do understand what you mean; I first encountered this format
when I was a FidoNet sysop (from the late '80s through the '90s);
starting around 1989, e-mail was gatewayed between FidoNet and the
Internet, and by the '90s I began to get spam through that gateway to my
BBS, usually quoted-printable encoded (though not yet HTML format; that
came later), which my BBS software (Opus) couldn't make head nor tail of.
