Yes, assuming no wraps in the lines, and assuming that you run 'newaliases'
after saving the file.  I don't see anything wrong on a quick glance :)

If you're running 1.8d you can add

listtrain-l-subscribe-request: "|/usr/local/bin/lsv_amin /projects/list/spool
listtrain-l-subscribe-request"
listtrain-l-signoff-request: "|/usr/local/bin/lsv_amin /projects/list/spool
listtrain-l-signoff-request"
listtrain-l-unsubscribe-request: "|/usr/local/bin/lsv_amin /projects/list/spool
listtrain-l-unsubscribe-request"

(again, make sure they do not wrap) as well.
