    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.

    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.
