Good afternoon,

I'm having trouble sending email to google.com domains, the emails returned, with the following message appearing:

There is no problem with Proxmox Mail Gateway, the problem is your IP address and/or your mailserver itself.
Read the support page from google, you can find all information and instructions how to fix this problem there.

If you have further problems, I would recommend you to post in the google forums. This is the wrong place as it has nothing to do with Proxmox Mail Gateway.

Yes, though, I can change the IP that is being used on MX and now our IP is no longer on the RBL lists, I would like to know how or Google updates this on their basis.

Thanks in advance for your attention.
