It can be done securely : just use smrsh to set up a local handler for
the tasks, and put in a virtusertable entry pointing to the handler for

I've used it for story submission and a couple of other tasks, linking
back to a database. The security on my system was limited to source address
and plaintext password in the mail, but you could extend that easily enough
to PGP or whatever.
