Dear Spicy People,
recently i noticed we cannot receive mails from Yahoo.com in our server. Our server runs MS Exchange 2010 Standard. Mails sent to our mail server from yahoo get rejected. Please can you help me trace this out or is it a problem from yahoo servers? I can receive mails from gmail and hotmail but not from Yahoo. Below is the Maeler-Daemon message from Yahooo:
