No. You could enter all recipients into /etc/aliases as well, without providing valid login IDs for them. > 2) Qpopper requires the user to have a valid user id and password to >connect to the POP server. Yes. But Qpopper doesn't require them to have a valid shell. So putting /usr/bin/false as the login "shell" should effectively prevent them from logging in (and even from ftp'ing, unless you're also entering /usr/bin/false into /etc/shells). -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
