QMail and funky file permissions?

Actually, although the file is in /var/qmail/alias it's not a qmail file. I
just keep it there so when we set up a new alias, we remember to create a
short code that willl be built into the LDAP configuration.

The other advantage is that both machines are on the same LAN, so the
likelihood of a copy fail should be fairly remote. One of the files is
delivered over Internet VPN by FTP from the US, so if anything, it's going
to get truncated before the rcp :-)

..and it's got bog-all to do with Linux!
