Yes, I can see you sent the original on Dec 8. It is captured in the archiv=
es correctly as having been sent only once and on Dec 8. The resending on D=
ec 23 is not shown in the archive. The same is true for a message Magnus se=
nt on Dec 12 that was resent on the 23rd as well.=20
http://www.ietf.org/mail-archive/web/mmusic/current/maillist.html

When I replied to Magnus's e-mail on Dec 14, it went out to the list correc=
tly; however, I did receive an error report a few days later saying "Mail D=
elivery System <Mailer-Daemon@sessmg10.ericsson.net>" was unable to send th=
e message to Magnus's address.

I have attached that e-mail in case it is useful in troubleshooting this is=
sue.

Cheers,
Charles
