I think that this is a good idea. I personally am using Courier's filter capabilities to refuse to accept an SMTP message from anyone with an excite.com or netscape.net address. The error message I set up for this is something like "550 unsavory sender rejected". I've never had anyone complain about this; however, I run a comparatively small site. If there's general agreement here that the set of sites you mention are all more or less equivalently evil w/r/t spamming, then I'll block the rest of them in the same way. -- Lloyd Zusman [EMAIL PROTECTED] _____________________________________________ tmda-users mailing list ([EMAIL PROTECTED]) http://tmda.net/lists/listinfo/tmda-users
