    I installed ISPConfig on Debian (dedicated server), domain had SPF record. When I send an email to the users, there are some target servers refuse to talk.
    The below message copy from postfix queue.

    (host hnicpmaa01.vnn.vn[222.255.37.13] refused to talk to me: 521 hnicpmaa01.vnn.vn Service not available - no PTR record for 210.245.87.194).

    In addition, when i send email to yahoo, almost to bulk mail, some working fine
    How do I solve this problem?

    Please ask the provider who gave you the IP address 210.245.87.194 to create a PTR record for you.

    Hi energynetwork,
    You contact your ISP and tell them that point PTR record to your mail server.
