Not Receiving Emails RRS feed

  • Question

  • Dears,

    We have exchange 2013 installed on Win 2012R2, i can send e-mails from my organization e-mails to Hotmail,yahoo and i can receive from yahoo but not from Hotmail.

    I did change HTTP to HTTPS in firewall, and i blocked 2 IP addresses because it was spam "before that issue". I checked my public ip and its not listed in spam list and its not listed.

    Before that 2 changes i made i was able to receive emails from any where.

    What else can i check\do

    Best Regards,

  • Port 25 already opened. Problem was solved, i did restart exchange server and its working fine now.

    We have McAfee solution i think it was blocking the mails.

  • Mail flow happens over the port 25, make sure you have opened port 25 on the firewall.

    Also, do you receive any NDR when you send an email from any test public email id?
