What IP Addresses do you use

Hi,

I’m using your service to provide antispam to my mailserver. Currently, everything is working fine but I would like to increase security by restricting port 25 access to the server to only IP addresses used by your gateway(s). Can you please tell me what they are?

Kind regards,

Hi Neil,

Apologies for the delayed reply.

Our servers are mxsrv1.spamgateway.comodo.com and mxsrv2.spamgateway.comodo.com which resolve to 50.23.158.210 and 50.23.158.211 respectively.
