This is a known "feature" of, I think, sendmail 8.9.1. It was fixed
in the next release, 8.9.3, and there was a patch by, I think (again :);
I'd have to check my email archives) John Beck for 8.9.1.
[The sendmail release notes attribute the bug report to me, but the problem
was originally discovered by Roland Rosenfeld and Thomas Roessler IIRC.]
Somewhere along the line, a particular instance of sendmail is messing
things up.
