=3D may be the common one, but =20 and =09 are others that end up showing up when whitespace gets quoted for various reasons.
Another one is =46 for 'F'. Why? Because some mailers think that "From" at the beginning of a line is the mbox beginning marker, and they'll escape any line that begins with "From" to use "=46rom" instead.
Those mailers are wrong (at a _minimum_ it's "From " with a space, and you generally should be even stricter than that), but it happens.
And obviously, if there is real 8-bit stuff, you'll get all the real odd hex noise.
