It is. > Is this a commonly accepted practice in the Internet community? You should have permission by the relay machine's maintainer/owner in order to do this. It's sometimes useful, for example poor freefall.freebsd.org dumps the entire email traffic for several top-level domains (.au, .de, .fr, .za, to name a few) to configured relay machines there. This distributes some of the mail load (mail to many recipients can be fed to the relay in a single connection). -- 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. ;-)
