Not having the same problem, but an explanation
from the place where the server runs:
The R mailing list server indeed has had hard times, as it seems
since early Sunday (CEST), and a complete time out for a few
hours during this morning. The symptoms have been that some e-mails
were badly delayed.... and --- as you have experienced --- mail
server timeouts do lead to e-mail being sent more than once.
This is the consequence of a safe e-mail server behavior: If an
e-mail "may have been lost", rather send it again.
As some say: Better error on the safe side.
