If I do nslookup for domain mail addresses like @sdfhsu.co, @binaloodagri.co, etc. almost all of this crap is translated to 80.249.161.171. I've tested it also in some online tools and it is th...

Getting spam from domains without DNS records

Re: Unwanted outbound emails
Yes, that's correct, my fault. I thought that all mails from Exchange server go through another relay server.

Thank you.
