It's a new bug.  X-DCC headers have had '\n' characters for years as
required by RFC 2822 when the header is longer than 78 caracters.  The
bug is that version 1.3.21 calls smfi_chgheader() with a trailing '\n'.
I saw sendmail complaining about that a few weeks ago but misdiagnosed it.

I'll release 1.3.22 with a fix tonight.

I'm sorry about that,
