Why Is This Happening?

You may receive mail delivery errors if our server has ended up on an RBL (or Blacklist). If so, messages you have sent (which resulted in a return error) were not delivered to the recipient. Our entire subscriber base shares the @cvctx.com e-mail addresses. Delivery problems can occur when one (or more) of our subscribers do not properly protect their computer(s) from viruses, or they fail to use secure passwords for their e-mail accounts.

When viruses or spammers infiltrate an account they send large amounts of spam originating from that address. The owner of that e-mail account is usually unaware this is happening. The receiving network of these spam attacks will then report cvctx.com to a Blacklist. Mail servers that reference incoming mail against Blacklists will then reject incoming messages from @cvctx.com accounts to guard their servers against abuse.

What Precautions Does Colorado Valley Take To Ensure Successful Mail Delivery?

Our mail server admins do the best they can to ensure our domain is not Blacklisted by suspending reported e-mail accounts and monitoring for spam attacks originating from our accounts.

The broadcast of these spam attacks can be very rapid. By the time an account broadcasting a spam attack is discovered large amounts of mail may have been transmitted from that account. The amount of mail sent before the account was suspended may be enough to cause a Blacklist report.

What Precautions Can I Take To Protect @cvctx.com E-mail Accounts?

Make sure your passwords are hard to guess. Don’t use a password that is the same as your username, or a password such as the word “password”. If you feel your password is easy to guess, please login to Webmail, click Preferences and Change Password.

Make sure your computer(s) has updated anti-virus software. For more information please see our Internet Security page.
