It's pretty normal it doesn't resolve. I think what changed was
that sometime yesterday wanadoo's dns servers removed the wildcard
*.wanadoo.fr mx entry (maybe I got shifted to a new nameserver,
it happens from time to time, or perhaps they thought it was a
security hole). In any case, my From: header was changed (as
usual) by mutt - seems like the "From " header was being left as
dave at bolsh.wanadoo.fr, and therein lay the issue. Thanks to Liam
Bedford, davew, Niall and Wesley Darlington for their help &
insights - by adding a re-writing rule for exim in exim.conf, I
solved the problem.

Yup - that's what I did. I added the following in the exim.conf
rewriting configuration:
*@bolsh.wanadoo.fr ${lookup{$1}lsearch{/etc/email-addresses}\
			{$value}fail} frFs

Cheers,
Dave.
