send email to internal users from BPOS RRS feed

  • Question

  • Hi,

    Here's a short description of my situation:

    I got BPOS domain msonline.com configured as authoritative. I added my own domain domain.com and set it as external relay and default domain (with inbound email disabled). I got test user configured at BPOS with address test@domain.com (alternative address is test@msonline.com). On my mail server (postfix) I configured forwarding rule so mails to test@domain.com are forwarded to test@msonline.com.
    My problem is when I send email from OWA from address test@domain.com to anyone in my domain *@domain.com my mail server rejects these emails. It's normal and desired behaviour because it protects my users from receiving emails from spamers.
    I use SPF. I don't know how to implement this tricky interdomain forwarding idea.
    I think the only workarounds for this problem are:
    1. Disable SPF (I'd not do it)
    2. Use another domain and direct it's MX records to BPOS server (I'd not do it)
    3. Add BPOS servers' IPs (which are sending/forwarding mail to my domain.com) to SPF config file but what are these IP addresses?
    4. I'd be glad enough if I could cofigure BPOS to send emails to domain.com from msonline.com and to send emails elsewhere from domain.com. My users at domain.com will know that test@domain.com and test@msonline.com is the same user and outer mail recepients will get emails from domain.com. Is it possible to configure BPOS that way?

    What's the proper solution to this issue?

  • Hi,

    You are right. Since your Postfix server considers these mails to be a SPAM or a SPOOF, it rejects all the mails from outside. Now, you need to configure your postfix such that BPOS FOPE as a trusted server.

    If your server does a SPF check and so it is rejects the mail, then you need to modify your spf (Not delete).

    Eg :

    “v=spf1 include:spf.microsoftonline.com a:example.com ~all "

    Refer : http://technet.microsoft.com/en-us/library/cc742638.aspx

    Below are the FOPE IP range. You can add these IP to your local server such that it doesnt rejects mail from these IPs.

    12.129.20.0/24
    12.129.199.61
    12.129.219.155
    63.241.222.0/24
    65.55.88.0/24
    206.16.57.70
    207.46.51.64/26
    207.46.163.0/24
    213.199.154.0/24
    213.244.175.0/24
    216.32.180.0/24
    216.32.181.0/24
