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.

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.

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.

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.

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.

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.

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

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.

This incident has been resolved.

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.

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.

A fix has been implemented and we are monitoring the performance.

We are continuing to monitor for any further issues.

This incident has been resolved.

We are currently investigating an issue that is affecting MailFlow Monitors. Currently they will show as down. This is a false positive that is affecting all MailFlow monitors. We appreciate your patience while we investigate and resolve this issue.

We are releasing a fix that will resolve the MailFlow Monitoring...expected ETA is one hour.

The incident with the MailFlow monitors has been resolved and the system is functioning properly now. Thank you for your patience and understanding during our investigation and resolution implementation.

Notifications for MxToolbox Monitoring were not sent between the period of 10:00 am CST on 7/9/24 and 9:30 CST on 7/11/24 due to an API issue. The issue was fixed and the service is operational again.

After monitoring the behavior of the abuse.ro blocklist and the false positives they are issuing, we have disabled that list from our toolbox. This should prevent any further alerts from being issue to you regarding this list. We will continue to monitor the lists health and stability before re-enabling it for our customers. Additionally, these false positives should not have an impact on your email delivery. Thank you for your patience and understanding.

We are continuing to monitor for any further issues.

After monitoring the behavior of the abuse.ro blocklist and the false positives they are issuing, we have disabled that list from our toolbox. This should prevent any further alerts from being issue to you regarding this list. We will continue to monitor the list's health and stability before re-enabling it for our customers. Because of the high volume of false positives from abuse.ro our queues are a bit backed up so you may continue to receive already process notifications. Once the queue is done you should not receive any more. Additionally, these false positives should not have an impact on your email delivery. Thank you for your patience and understanding.

This incident has been resolved. Abuse.ro was permanently removed from the Blocklist Monitoring service.

This incident has been resolved.

We experienced a server upgrade that has triggered false positive alerts on MailFlow and potentially some standard monitors. We are currently working on a patch to resolve this issue, and expect it to be resolve within the next few hours. If you are experiencing the false positive alerts you can view your MailFlow pings in your dashboard and see that they are being process, with a server delayed time. This confirms that the pings are being process so your mailflow is not down. We apologize for the inconvenience.

The Monitoring & MailFlow False Positive issue has been resolved.

We are currently experiencing connection issues to a limited amount of networks. This is impacting some monitors from being able to query certain systems and may cause false positives. We are working to identify the root cause and resolve the IP issue. If you are experiencing false positives with your configured monitors you should add the following IP Address to your gateway / network allow list; 18.209.86.113/32 18.205.72.90/32 44.194.168.193/32 52.55.244.91/32

We have identified a IP reputation issue with Talos that likely caused the connection issues on limited gateway appliances, and have been informed that they are clearing the reputation issue. We are continuing to monitor the performance and reputation issue and expect it to improve over the next 24 to 72 hours. To prevent the false positives going forward you should add the following IPs to your gateway / network allow lists; 18.209.86.113/32 18.205.72.90/32 44.194.168.193/32 52.55.244.91/32
