Thanks for your comments. I think I identified another problem
though. None of the Content-* directives I put in the header at
the sending end remain intact at the receiving end. Small wonder
the mail client doesn't know what to do. Grumble.

The sending end uses xmail rather than sendmail. I wonder if
that may be an issue. I'm beginning to wonder if I'm not better
off moving everything back to the old host.

Never try to fix something that works...
