  • Question

  • Hi all, I have exchange server 2010 deployed and can receive mail with no issues but cant send mails to some external domains. I can send mails to gmail some others. Yahoo! is among the domains that rejects mails originating from my exchange server. Is there anyone to assist please?

  • You are probably blacklisted, or something else about your network (IP address, domain name, ISP, SPF record, etc.) is causing Yahoo! to think you might be a spammer.
