One really nifty side effect could be to make it harder to spam through other ISP's relays if the relays which had to be relatively open for customers weren't visible on the 'net at large.Your customer relays never have to be visible to the net at large. Remember, sendmail is a "mail router"
yes, but our relays also act as backup MX... its a long story, sigh. luckily Exim (http://www.exim.org) can be configured to do both relay and MXing controllably... and the documentation is plenty good enough to make it easy!
