Dear our customers,
We are continuing to improve our Comodo Antispam Gateway infrastructure to provide you a better service. In this context, we are planning to move our current EU data center to a new one on 24th February!
After moving data center, all of our EU instance customers should make below configurations in order to continue using their ASG system without any interruption.
First
Configure your firewalls and add to your Recipient Filtering or Transport Rules are 144.168.192.64/27 (EU) and 192.186.179.160/26 (US) to allow outgoing/inbound e-mail traffic.
Next
Could stay your DNS MX records same but you should refer to relevant servers by name for EU region: mxpool1.spamgateway.comodo.com
We do not recommend changing your DNS MX records during business hours as DNS records may take several hours to update globally. This may result in non-delivery or delayed delivery of emails while the global DNS update is taking place.
During the migration it may be possible to experience a brief service outage related to switch-over of DNS addresses and restart of services but it does not exceed 15 minutes even in the worst case.
We wish you a better service,
Oytun Yavuz
Product Manager of Anti Spam Gateway
