This is an artifact of using the digest version of the mailing list.

Many people have their email clients set to send in "quoted-printable" =

format.  In quoted-printable format, certain special characters are =

"escaped" to allow them to be sent through 7-bit channels.  If you've =

ever seen a message where every line ended in =3D20, that's the escaped =

version of a space character.

Because the equal sign is used as the escape character, a standalone =3D =

has to be escaped.  The hex value of the =3D character is 3D, so the =

escaped character is =3D3D.

When you get the messages through the normal mailing list, the header =

that says "this message is quoted printable" gets sent along, so your =

mail reader does the right thing.  For the digest, however, all of the =

individual email headers get stripped out.  The digest is sent as plain =

text, and as a result we see the escape codes in any messages that were =

originally quoted-printable.

A more serious problem is the people who send messages in Base64 =

format.  They appear just fine in the regular mailing list, but all we =

see in the digest is a solid block of random garbage.
