in.fingerd is on the system 
akira:~ # ls -l /usr/sbin/in.fingerd 
-r-xr-xr-x    1 root     root         8304 Sep 20  2001

The only mentions of finger in the logs corresponding to the list are

Jul 16 09:06:19 akira in.fingerd[10836]: connect from nobody at 127.0.0.1
(127.0.0.1)

Which appears when I try to sign up through the browser interface -
nothing appears when I try to send a mail to the list from an external
account - which would make sense because we don't allow finger requests
through the firewall.

The finger appears to run through fine - as it must have seeing as the
output of the finger command is in the mail sent to root.  The only
errors in the strace log are quite a few along the lines of

13127 close(61)                         = -1 EBADF (Bad file descriptor)

But nothing else except for a few grumps about .plan's not being
readable
I can send the trace to someone if they have the time/inclination to
have a read..
