My email address has been spoofed by several rascals. It’s my email address & domain, but the smtp & addresses sending are obviously different. My question is; if I mark these emails as spam am I going to cause problems for my domain / IP address or just the the actual spammers & their smtp address & domains? Blacklisting the email is proving an enormous task as the spammers are constantly changing.
Thanks for any help / advice.
Are you using Yahoo email? This is rather normal with Yahoo. I suggest switching to something like Gmail or Outlook.com.
