The Best Web Hosting List

If you call or contact some of the best web hosts, you might come across the term “blacklisting”. Basically, blacklisting happens when an email service thinks they are getting spammed by a certain server — they “blacklist” that server and block an incoming email from that server.

I’ll spell it out in examples and explain , since I quite like examples

You’re on a shared server with 300 other customers. One of those customers has a large mailing list and many Yahoo! accounts. He send out email and a number of the Yahoo! customers don’t remember signing up for the list, so they mark his email as spam. Yahoo takes the spam claims seriously, looks into the matter, and finds that these emails were sent by on account holder on a specific server. They then blacklist that server, disallowing all incoming emails from that server. How this affects you if you’re on that server is, you can email hotmail accounts, you can email AOL accounts, but any Yahoo accounts you try to email won’t go through. In these cases, the webhosts are alerted to the problem, investigate the alleged “spammer” on their server, and work with Yahoo to get them white listed again.

Because this is ALWAYS a risk with any shared hosting, companies who rely heavily on email communications might choose to go with a VPS or Dedicated server to lessen and eradicate this possibility.
