If the capitalization issue is not causing the problem, then the character
after the ":" in the misbehaving headers must not be a real [SP] (' ') char,
but something that just "looks like" one.  e.g. a '\0xA0' character, used by
MS as a 'non-break' space.  This is a violation of the Internet mail message
format, as it explicitly requires a [SP] character to separate the header
name field, from the value field.  But, given the sender is using home-brew
mailer software, it wouldn't be all that surprising to find 'another' standard
violation in their software.

Anyway,_IF_ that's the case, then removing the from the recipe =will= fix the
problem.

Nick may have had the right solution, albeit for the wrong reason.  <grin>
