Hello everyone, I finally decided to begin my journey to earn money by internet marketing and in this case by email marketing. I ordered VPS with windows OS, then I installed IIS6, In ISS I added new SMTP domain, in advanced IP settings I changed my TCP port to 2525, I didn't know if I need setting relay and how to accurately do it. in one special site i checked if my domain has everything ok (dns, reverse, resolves), everything turned out ok. Then I installed Atomic Mail sender on my VPS, I configured mailer settings and added smtp server domain with port 2525 with authentication entering my login which i created in my vps settings but when I try to send test email to my personal mail at gmail it doesn't do anything, then I changed port back to 25 and it showed that it successfully managed to send it but I didn't receive it. Now can anyone please explain me what did I do wrong or what I haven't done to successfully send mass e-mails. You can answer here or through PM, the help would be really appreciated because I am really motivated to develop my skills in this area but I don't know where I made mistake.
