What is happening, I guess, is that Mailman is folding that header to
keep it within some number of characters, maybe 76 or so.  RFC 2822
specifies that this may be done by inserting a linebreak (CRLF) before
whitespace.  The RFC implies that the right thing to do in that case
is to remove the CRLF only, but some MUAs also remove a space.  I
suspect that is what is happening to this case.

Can you post a copy of the "raw" header as received by Mailman and as
sent by Mailman?
