DMARC compliant email is now a requirement to get into the inbox at Google, Yahoo! and /Office365. Are you using multiple 3rd party email providers? You should evaluate their performance and make sure each of them is in your SPF record and no one else.It is easier to have all of your email blocked by a blacklisting event if you are sending from a single IP address or small block. Are you still hosting your own email? This could be an opportunity to investigate Inbox Providers that have improved spam filtering and email sending capabilities.Take the opportunity to evaluate your email sending configuration, blacklists are not the only reason your email is failing to make the inbox. They make money by being relevant to email delivery decisions and sometimes they get over zealous. Be patient! Blacklists are not out there to attack your legitimate email, they are there to protect everyone from spam and phishing attempts. We know that being on a blacklist is affecting your business. We will watch this issue but will also continue to show UCEPROTECT listings as long as they are being used for email delivery decisions. We have noted that some companies are dropping UCEPROTECT from their decision criteria due to the recent activity. Our criteria requires the blacklist to be used to make email delivery decisions. MxToolbox regularly reevaluates the list of blacklists we check.You can learn more about how UCEPROTECT lists ASNs here. In this case, the entire ASN should be automatically delisted when the UCEPROTECT SPAMSCORE for that ASN drops below a certain level in a 7 day moving average. Legitimate blacklists, including UCEPROTECT, have free ways to be delisted. Feel free to ignore a blacklist if you think it is not relevant. We give you the opportunity to see who is listing your IP address and do not endorse any blacklist. MxToolbox is not blocking you, the Inbox Provider is blocking your email because your IP address or domain is listed on a blacklist that they are using to make email delivery decisions. DO NOT make decisions exclusively based upon a listing on the Blacklists we check. We provide Blacklist lookups for information purposes only.However, this includes many popular services so many legitimate businesses have also been affected. The purpose of this particular UCEPROTECT blacklist is to block ASNs that allow spam to be sent from a large number of IP addresses in the network, often these are ASNs setup for spam or providers that do not adequately police their customers. If I can test or do something on my end to help, I would be happy to help in any way I can.Recently, we noticed an increase of in the number of ASNs (full blocks of IP addresses owned by individual Internet Providers) listed by UCEPROTECT on their Level 3, aka Draconic, blacklist. So thank you w0lfschild, and to all who contribute. Thank you for your efforts in making these features available as I would not be able to re-learn how to code without it. Doctor Dark enables me to recreate the color schemes I learned how to program with so my eyes/brain don't have to work as hard. I had to cover up my windows, and even painted my walls black. I wear sunglasses indoors, even at night. My eyes are also very light sensitive so I bought some Lifx bulbs and tune them to make it easier on my brain. I had to stop driving because my brain cannot process that much information at one time. 60 minutes of programming and I have a hard time keeping my balance. I am significantly impaired as I can no longer count or do basic math. I learned how to code in 2nd grade (late 70s) and was an IT exec, but I was rear ended in 2014 and have suffered brain damage. I just wanted to say thank you for developing Doctor Dark. I'm a Github noob so if I should be posting things somewhere else or in a different format, please let me know.
