emails getting blocked while sending by Blocklist1 RRS feed

  • Question

  • Hi

    i have setup my exchange 2010 server, i have problem sending emails to one of my client. Below is the error,

    TX2EHSMHS037.bigfish.com rejected your message to the following e-mail addresses:
    business.customercare@du.ae (business.customercare@du.ae)
    TX2EHSMHS037.bigfish.com gave this error:
    Service unavailable; Client host [94.2xx.1xx.xxx] blocked using Blocklist 1, mail from IP banned; To request removal from this list please forward this message to delist@messaging.microsoft.com and include your ip address 94.2xx.1xx.xxx . 

    Your message wasn't delivered due to a permission or security issue. It may have been rejected by a moderator, the address may only accept e-mail from certain senders, or another restriction may be preventing delivery.

    Kindly suggest, Thanks

  • Hi,

    Please use http://mxtoolbox.com/blacklists.aspx to verify whether we are in the blacklist.

    If it is the case, please contact bigfish.com domain to accept our domain.

    If not, please contact our ISP for help.
