Update - 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.

Update - 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.

Update - We are continuing to work on a fix for this issue.

Update - 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.

Update - 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.

Update - 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 - 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.
