AS version 1.59, revision 7, I assume?

While decoding an 'encoded word' (see RFC2047), the reconstructed header
string became longer than 255 characters. This is unusual, as decoding
should always result in a string shorter than the original.
Earlier versions of AntiSpam could crash on this function if the 'end of
encoded word' marker was missing. From version 1.54 this should have
been fixed, though.

I'm guessing the header causing the problem contained an end marker
before a start marker. That shouldn't happen of course, but neither
should spam. Changing the bit in line 4206 that reads




should take care of this.


In AS 1.60 alpha 5 line 4206 has moved to 4257.
