[exim] Finger

Hi guys,

We have just migrated to a new Exim server. The old server used to
allow 'finger domain@server' to be submitted by certain clients to
poll the queue but this functionality doesn't exist on the new server
at the moment.

I have been tasked with getting this working again, but the old server
has been ditched. Does anyone have any clues as to how to create a
custom fingerd to accomplish this? We need it running for
compatibility reasons. Any ideas/pointers would be greatly
appreciated.

Many thanks for any assistance,

Doug
