In my last post I discussed a number of the steps we take to try and keep spam out of your mailbox. I just wanted to take this opportunity to further expand upon the use of RBL lists. The idea behind RBL lists is to compile a list of mail servers which fall into one of the following categories:
- Open for relay – meaning they are easily hijacked by spammers.
- Disreputable ISPs that allow spammers to use their email servers.
- ISPs that do not actively respond to spam complaints against their servers by disciplining or shutting down users who spam.
By listing these email servers in RBL lists and actively using these RBL lists to block unwanted mail, we’re all doing our part to encourage bad ISPs to clean up, and to encourage consumers to use secure and reputable email hosting services and ISPs.
Although we feel we’re fighting the good fight, sometimes innocent users end up getting caught in the crossfire. Some users may not agree with the use of RBL lists, or may be unwilling to change hosting providers. So this is our motivation for providing the new Whitelist feature which allows you to decide whether you want to allow mail from select servers that appear in the “Blacklist”. This allows you to enter the IP Address of the sender’s server into your domain-level Whitelist, which will circumvent the RBL for that domain. We even make it easy for the sender and the recipient by providing them with a method to easily request and approve the Whitelist entry.
We feel that these steps give you the best of both worlds, protecting you from the bulk of annoying and unwanted email, while still allowing the email you want to receive to come through. I hope this helps shed some light on the subject.
