Yup, that got it. Your own message was dup'd to me, and I found out
what was wrong. When I got back to my apartment finally, from the
extended hospital stay, all of my mail subs to chuckr at freebsd.org had
lapsed from non-receipt. I'd lost my old FreeBSD machine, and while I
was still pretty disabled, it took me a long while to get the machine
and all the smoking hardware back in service, and when I did, I
restarted all my old subs, but because I'd lost the machine, all my old
ssh keys went up in smoke, and I now couldn't get back into my
freebsd.org login (remember I was a committer) so I was forced to
restart my mail fromm my own hosts at chuckr.org. Well, somehow, all
the old FreeBSD.org subs kicked back in finally (they must occaisonally
test forever, because I was laid up about 6 months). So, all I need to
do is to single up my subs. Too bad I couldn't get the new mail
application to do what the old majordomo would do (give me the list of
all lists a particular login name is subscribed to).
So.thanks for kicking me into doing that testing.
