Several of my emails are getting returned by the intended receiever's ISP. The emails are returned with "invalid hostname" -- *my* hostname. Since I am currently only using PPP to connect to the 'net, I have a bogus hostname.
I believe, though, that some mailers reject my name because of spam filters or whatever. At any rate, what should I change my hostname to (and how) so that it appears okay for strict mail systems? My ISP IP is dynamic, so I can't use that (those?). Help! Thanks.
