Hopefully we all agree spam is the enemy. However, if you have a website that generates emails such as a forum site, it seems getting all the settings right helps make sure the mail gets through. My trail on this started with a discussion on MX entries, but like a loose thread in a jersey, it seems to be getting more complex all the time. At this point I still seem to have a few problems and hopefully can get some ideas and suggestions here. I looked up theforumsa on robtex http://www.robtex.com/dns/theforumsa.co.za.html and am bugged by the comment entire tld is rfc-ignorant. Guilty as charged, but being ignorant, I don't understand why exactly. Can anyone help/steer me in the right direction? This quest for understanding led down all kinds of roads, but my other question for the time being - does anyone have any feedback on submitting for whitelisting at a site such as http://www.uribl.com/index.shtml Does it help? Is it worth it? Any other comments?
