Whoops, you're quite right (confirmed on MSDN).  We should actually catch
that in cygrunsrv and print out an appropriate error message.  Corinna,
should I prepare a patch, or do I need a copyright assignment for

Hmm, perhaps something along the following lines will work instead:

cygrunsrv --install fetchmail --path /usr/bin/su.exe --args "-p -c '/usr/bin/fetchmail --daemon 300 --nodetach </dev/conin 2>/dev/conout' domain\\user" --env HOME=/home/user --termsig TERM --shutdown --type manual --interactive

The above assumes that fetchmail prints the password prompt to stderr, and
the rest of the messages to stdout.  FWIW, I've tested this using a bash
script that used "read" to read a value...  And before people ask: yes,
you really *can* use "su" from a system-owned process.

Hope this helps,
P.S. Corinna, there's a bunch of typos in the cygrunsrv messages as well
("neverexists" instead of "neverexits").
