If your ChoralNet email has stopped flowing recently, you're not alone. ChoralNet, along with many other legitimate sites (including Amazon and Yahoo) were recently incorrectly added to a "real-time email blacklist" of supposed dynamic IPs called the SORBS DUHL. This blacklist is intended to provide a point of data that your email server uses to determine whether a given message is delivered or rejected as spam. ChoralNet neither sends spam nor is on a dynamic IP. Our service provider, along with those of many, many other legitimate sites, have requested that their mail servers be removed from SORBS' list. SORBS has become increasingly unreliable and unresponsive, partially as a result of this and other problems, and we have no estimate as to when this issue will be resolved. In the meantime, there are a few things you can do to ensure that your subscriptions from ChoralNet get delivered:
- Have your mail administrator whitelist choralnet.org. We work diligently to assure that any mail sent from choralnet.org is genuine, relevant, and not spam. You can ensure continued delivery of your ChoralNet mail by having your mail server administrator "whitelist" mail from choralnet.org domains.
- Have your mail administrator remove SORBS from their list of mail blacklists. Many leading ISPs now actively discourage using SORBS as a blacklist provider due to their recent reliability and responsiveness problems. A quick web search for "SORBS DUHL issues" will reveal many sites having substantial problems over the last few weeks. If your ISP or institution uses SORBS, urge them to consider using other blacklist providers. SORBS themselves points out that the SORBS DUHL is not intended to be used as a single-point email blacklist; if your email provider uses it as one, your provider's email server is misconfigured. There are many other real-time DNS mail blacklist services available, and your system administrator can resolve the problems by removing any sorbs.net blacklist providers from their list of email blacklist providers and using different providers, at least until SORBS solves their current problems.
- Restarting your ChoralNet subscriptions. If you've whitelisted choralnet.org or had your system administrator remove the SORBS blacklist from your e-mail server's blacklists, you will likely need to restart your ChoralNet subscriptions. To do so, log into ChoralNet, and then from the My ChoralNet dropdown menu, select Subscription email options and choose how you would like to receive your subscriptions.
- Read your subscriptions on the Web or by RSS instead of e-mail. You can receive your ChoralNet subscriptions either directly on the Web or via RSS rather than by e-mail. To read your subscriptions directly on ChoralNet, you can log into ChoralNet, and from the My ChoralNet menu, select Read my subscriptions. If you use an RSS-compatible news reader or mailer (like Google Reader or Bloglines, or Mail.app on the Mac or Outlook 2007 or better) you can also read your subscriptions as an RSS feed. To do this, log into ChoralNet, and from the My ChoralNet menu, select Read my subscriptions, then click the RSS icon in the Address bar of your browser (it will look something like this: ) and follow the instructions.
