  • Yahoo Mail delivery failed

    I have exchange 2010 Server SP1 on Windows 2008R2. I can send mails to externally to gmails,hotmails but I'm having an undelivered delayed error message when I send to an yahoo account. Is it Exchange blocking it, is there workaround to this problem?

    Your assistance is appreciated.
    Regards

    Check if your public IP or domain name are on any blacklists -- the fact that others receive your emails strongly suggests that the problem is at the yahoo! end

          550 4.4.7 - Queue Expired

          The message sat in your mailqueue for too long.

          from your mailserver, i would attempt to make a connection to the Yahoo mail servers on port 25, see if it tells you what's going on

          Normally - this either means it cannot connect to the remote host - which would suggest you're being blocked one way or the other

                  Hi, I just did a blacklist check on mxtoolbox.com for naurugov.nr and you're on a blacklist. I would resolve that first.
