Notice December 11, 2024 Deferred emails to Prodigy-protected and Rackspace-hosted domains 40d 19h CloudFilter and SafeSend Email Security
Started Dec 11, 2024, 08:36 PM UTC· resolved Jan 21, 2025, 04:24 PM UTC
- identified Dec 11, 2024, 08:36 PM UTC
Mailprotector resolved a significant reputation issue that affected AT&T and Yahoo domains. As part of that remediation, the volume of emails from affected servers significantly dropped. As the affected servers have been put back into service, some domains using Prodigy (part of AT&T and Yahoo) and Rackspace are deferring email delivery due to the rapid volume change. Mailprotector is mitigating the occurrence of deferrals by metering the volume of affected servers. This process will take several more weeks to reach full resolution.
- identified Jan 03, 2025, 09:57 PM UTC
Mailprotector has observed improved deliverability to Rackspace and AT&T domains. However, we are cautious, given that email volume is typically reduced between the Christmas and New Year's Day holidays. Over the coming weeks, we will move affected servers back into full production and wait for stabilized delivery responses. We expect some deferrals because these email service providers do not offer a means to set an expected volume of emails. We cannot eliminate deferrals entirely, especially if an email is considered questionable for spam or malicious intent. If the process moves forward smoothly and as expected, we will send one more update in a couple of weeks. We hope to consider this incident complete.
- resolved Jan 21, 2025, 04:24 PM UTC
Deferrals of emails have slowed substantially but have not ceased altogether. Deferrals to certain email service providers will always occur due to several factors, including domain and sender reputations. Mailprotector deems the IP reputation problem resolved at this time. Mailprotector does not control domain and sender reputations. IP reputation management is influenced by Mailprotector's sending infrastructure management, but it is not solely in our control. Deferrals may happen on occasion. Users will see a deferral notice under the right circumstances as we continue to manage the sending infrastructure to build additional resilience and strictly enforce the sending policy. If a deferral or bounce is questionable, please open a support request, and Partner Success will gladly explain the situation as best as possible. In a pinch, the option is to send emails directly from the email service provider rather than CloudFilter's smarthost relay.
Minor October 30, 2024 Bracket encryption from CloudFilter 2h 29m Bracket Encrypted Email
Started Oct 30, 2024, 03:41 PM UTC· resolved Oct 30, 2024, 06:11 PM UTC
- investigating Oct 30, 2024, 03:41 PM UTC
Some attempts to send Bracket encrypted emails from CloudFilter-protected accounts are failing due to a TLS error. We are investigating the issue. Sending Bracket emails directly from https://bracket.email or Shield is working as expected.
- identified Oct 30, 2024, 03:50 PM UTC
The issue has been identified, and the team is working on implementing the fix.
- monitoring Oct 30, 2024, 03:56 PM UTC
The TLS connection issue from CloudFilter's outbound gateway to Bracket is fixed, and we are monitoring the logs to ensure resolution. Bracket encryption from CloudFilter-protected accounts is operating as expected.
- resolved Oct 30, 2024, 06:11 PM UTC
We have confirmed the TLS connections between the affected CloudFilter outbound gateway servers and Bracket have been working as expected.
Notice October 28, 2024 Deferred or bounced email to AT&T and Yahoo services 44d Service Announcements
Started Oct 28, 2024, 07:58 PM UTC· resolved Dec 11, 2024, 08:31 PM UTC
- identified Oct 28, 2024, 07:58 PM UTC
Mailprotector is aware of IP reputation issues sent to email addresses associated with AT&T and Yahoo. The team has been working to mitigate the chances that emails to those email services are deferred or bounced, but AT&T and Yahoo control this. More information is being prepared to provide options for temporary workarounds. A link to that information will be shared soon.
- identified Oct 28, 2024, 08:50 PM UTC

- identified Nov 04, 2024, 03:14 PM UTC
The team has observed progress on some IP addresses but is still waiting for others to present better deliverability statistics. We continue following the email service providers' processes and rotating resources as needed. Users will continue to receive some deferral and bounce notifications.
- identified Nov 06, 2024, 10:18 PM UTC
Progress has been made with AT&T services, but it is not completely resolved. Some deferrals are still being reported. Yahoo has also improved, and we continue reporting evidence to resolve the deliverability issues. Reports of deferrals and bounces have decreased significantly. However, we will still monitor and manage the situation until the outbound servers are 100% healthy.
- identified Nov 08, 2024, 02:43 PM UTC
Mailprotector has observed a decrease in bounced emails; however, there has been an increase in deferrals. We have moved resources in response to this behavior and have reached out to AT&T/Yahoo again. We continue to work on resolving the issue to resume expected deliverability. Please see https://support.mailprotector.com/hc/en-us/articles/31650407848852-Deferrals-or-bounces-sending-email-to-AT-T-or-Yahoo-email-addresses if you need to consider a workaround.
- identified Nov 12, 2024, 11:11 PM UTC
More progress has been made towards improving deliverability to AT&T/Yahoo-owned email domains. Mailprotector has received an automated response from AT&T, which indicates that the request for reputation delisting is being escalated. We do not know how long that will take, but seeing a meaningful behavior change is encouraging.
- identified Nov 15, 2024, 03:21 PM UTC
We are continuing to work on a fix for this issue.
- identified Nov 15, 2024, 03:23 PM UTC
In the last 24 hours, Mailprotector has improved with Yahoo domains. However, AT&T domains are still deferring or bouncing with some servers. Unfortunately, the deferrals are held for 24 hours, which delays the user and Mailprotector learning that a server is still affected. Servers found to be still affected have been rotated out of full production to minimize the impact on users. Deferrals and bounces will still occur since the servers will continue to be used at a significantly reduced rate.
- identified Nov 19, 2024, 10:04 PM UTC
Mailprotector has slowly increased the volume of emails sent from affected servers. This step is necessary to improve the server's reputation. However, due to their greylisting methods, AT&T and Yahoo email services may still defer some sending emails for 24 hours. The first increase in volume began earlier today, and we anticipate another increase later this week. Updates will be added as we have more information.
- identified Nov 22, 2024, 10:12 PM UTC
Deliverability has continued to improve over the past few days. The slow increase in the volume of emails from formerly affected servers is working, although it still creates some deferrals because of the protective methods used by AT&T property domains. The positive result of this "warming" strategy will continue. Another update will be sent when we have significant news or, hopefully, a resolution announcement.
- monitoring Dec 03, 2024, 01:27 AM UTC
Evaluating the logs bounces for reputation issues have been resolved. However, Mailprotector continues to see occasional deferrals from AT&T domains as servers are moved back into full production. The deferrals will subside as the server volume is slowly increased. We continue monitoring the logs to minimize the deferrals.
- resolved Dec 11, 2024, 08:31 PM UTC
The reputation issue with AT&T and Yahoo domains has been resolved. We have received confirmation from an AT&T representative that none of Mailprotector's sending servers are blocked.
