You can whitelist or blacklist anyone you choose. The downside is that so can everybody else; your lack of non-generic rDNS means that mail to my server (alcatraz.sequestered.net) will bounce if not smarthosted through somewhere that has a static IP and properly configured DNS. This was deemed an acceptable threshold on my box when I was selecting anti-spam mechanisms. If you're that concerned about privacy, use GPG/PGP and request a key exchange. What's more is that I've applied that same metric at several employers, ranging from mid-sized businesses to universities. My previous (and current!) employers were familiar with all sides of the argument and ultimately decided to reject mail from dynamic address pools to combat spam. Complaining about it doesn't do much good, since (as previously stated) their server, their rules. > To classify a whole load of users, the majority of whom are genuine, as > invalid users is degrading and discriminatory. > > The majority of users smarthost their mail. If you want to retain control, drop the $15 a month on a VPS somewhere with a static IP, configure DNS correctly, and be your own smarthost; I did this for a while before I upgraded to a static IP at home. > My point of viwew -- you are entitled to yours but IMHO not to enforce it!! > Ah, but on my server I can enforce whatever makes the most sense for my userbase; my responsibility is to them, not to you. -- Jay Chandler / KB1JWQ Living Legend / Systems Exorcist Today's Excuse: multicasts on broken packets
