Minor February 13, 2026 MailFlow Monitoring Impacted by SpamHaus Blocklisting 4h 49m Mailflow, Monitoring

Started Feb 13, 2026, 04:46 PM UTC· resolved Feb 13, 2026, 09:36 PM UTC

  1. identified Feb 13, 2026, 04:46 PM UTC

    We are currently experiencing an issue with our MailFlow Monitoring being impacted by being listed on the SpamHaus blocklist. Our Team is working to have our IPs removed from this list. Due to the nature of our monitoring tools, some of our IP addresses may be listed occasionally on certain RBLs. These listings may cause issues with certain anti-spam appliances/security software and result in a mailflow test message to not be delivered. As we do our best to remove the listings promptly, we recommend you add our IP addresses as a safe/allowed sender to ensure mailflow tests are uninterrupted. 44.194.168.193/32 52.55.244.91/32 18.205.72.90/32 18.209.86.113/32 We apologize for the inconvenience.

  2. monitoring Feb 13, 2026, 06:38 PM UTC

    Our IPs for MailFlow have just been removed from the SpamHaus listing...we are continuing to monitor the MailFlow connectivity issue that was being impacted by this listing.

Critical October 20, 2025 MailFlow Monitoring Down / AWS Outage 3d MxToolbox.com, Mailflow, Alert Notification Engine, API and 3 more

Started Oct 20, 2025, 03:18 PM UTC· resolved Oct 23, 2025, 03:31 PM UTC

  1. investigating Oct 20, 2025, 03:18 PM UTC

    We are currently experiencing an issue with our MailFlow Monitoring system, as Amazon "AWS" encountered an outage this morning. We are expecting their outage to be resolved soon. This AWS outage is causing the false positives. We will provide updates for this issue as they become available. thank you for your patience and understanding.

  2. identified Oct 20, 2025, 03:23 PM UTC

    The AWS outage was between 2am CST to 5:30am CST...however there are still residual effects of their outage. The MailFlow Monitoring system is still experiencing issues due to the AWS outage.

  3. identified Oct 20, 2025, 03:32 PM UTC

    This morning Amazon Web Services (AWS) had a global service outage and many of our services were impacted by that outage. AWS continues to have an ongoing outage on infrastructure that our monitoring service uses causing our Mailflow service to be down and other monitoring services to be degraded at this time. We are monitoring the situation and will keep you apprised when we know more.

  4. identified Oct 21, 2025, 02:32 PM UTC

    DMARC report processing is currently slow due to continued AWS outage impact. We are still processing them, but at a much slower pace - as such some report data from the last 24 hours may not be available yet.

  5. identified Oct 21, 2025, 02:35 PM UTC

    DMARC processing has been fully restored and is working with normal speed and frequency as of 4:30pm CST 10/20/2025

  6. monitoring Oct 21, 2025, 07:16 PM UTC

    As of 10:00 am CST this morning the MxToolbox Mailflow is up and running. However, the service continues to experience a system wide issue related to delayed ping processing. We are currently working to eliminate the backlog of ping messages that were delayed from being processed yesterday as a direct result from the AWS outage. We have added additional resources to help quicken the processing of those delayed ping messages. The Mailflow Service was impacted by the AWS outage starting around 1:00 am CST on 10/20/25 when AWS services became degraded. The Mailflow Service then experienced a full outage starting around 4:00 am CST when AWS suffered its main outage. AWS EC2 continued to experience an outage during the course of the day on 10/20/25, only resolving around 10:00 CST when full EC2 service was restored. During this time we continued to send and receive Mailflow ping messages, but could only process a small volume of messages during that time. Additionally, a small number of received ping messages were lost due to the AWS outage. With our system only able to process a limited amount of ping messages during the AWS outage our queue backed up with un-processed ping messages. Once the AWS EC2 outage fully ceased around 10:00 pm CST, we began fully processing the backed up messages. Our ping processing service from that point struggled to catch fully back up in processing the full backlog of ping messages. Our engineers added additional capacity to help with the processing and now the system has nearly caught back up to fully processing pings as expected. We are continuing to monitor the service and will have an update when the service is fully caught up on the backlog and operating normally.

Started Oct 01, 2025, 02:35 PM UTC· resolved Oct 01, 2025, 08:34 PM UTC

  1. identified Oct 01, 2025, 02:35 PM UTC

    We are investigating and issue that caused our MailFlow Monitoring to change our TimeZone to UTC. This is causing MailFlow monitors to report delays even though the do not exist. These are false positives, and our Team is issuing a fix as this is being typed. The behavior shows approximately 18000+ seconds in latency. We expect this to be resolved shortly. Thank you for your patience and understanding.

  2. identified Oct 01, 2025, 03:20 PM UTC

    We have isolated the issue causing false latency issues with the MailFlow monitoring system, and are testing the resolution. We expect to roll this out soon if tests pass.
