E-mail IP is blocked by Spamhaus.

HSG

Email server has been included in an Spam list ( Spamhaus) . Requested Spamhaus to remove my domain form the list as I was using it normally, I received the following answer:

"Requests to remove this shared IP from the CSS must be made by the Internet Service Provider/hosting provider/ESP/VPN provider who owns the IP address. If you are not sure what network that is, IP ownership can be determined from whois records using the appropriate website (for example: https://www.whois.com).

Please contact your service provider and have them contact us to discuss it.

We are unable to remove this listing without the cooperation of the provider. Thank you for your understanding!

Regards,"

Gmail also started to block my emails ( and thery were working correctly until yesterday),

This is the message received (I only hide my domain), and I had configured SPF and DKIM in my DNS

HSG The Gmail bounce indicates a missing TXT SPF record or another issue related to the TXT SPF. You didn't specify which domain you are referring to.

HSG

admin, yes, I feel sorry, this (the problem with gmail) was my mistake, I think this has been solved . ( it was a problem with the dns servers, I don't know why they changed and I didn't realized. Sorry!

HSG

admin Sorry, gmail started to block again my emails, and I think everything is fine... My domain is improvisapp.com

HSG

I tried to delete the message when I realized but I couldn't. But the problem with spamhaus still present

admin

HSG So check the reason for the blocking of emails by gmail.com.

HSG

Gmail today its not blocking emails ( I don't understand whats happening) however the problem with spamhaus its still active,

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

HSG Yes, we are aware that Spamhaus occasionally blocks email delivery from the s0 server, even though no spam is being sent. We are in discussions with them regarding this matter.

HSG

Is there any update regarding the email server block? Each day I have more email server blocks ....So I can only send emails to reduced destinations

admin

HSG There are no changes; from time to time, they unblock the IP only to block it again, without any sensible reason.
