    Cannot send email to hotmail via my mail server


    Hi, I've set up my email server using hmail (freeware)

    I've already passed the authentication test of SPF record & sender ID. (I sent email to port25.com) This is the result


    ******************************************************************

    This message is an automatic response from Port25's authentication verifier
    service at verifier.port25.com. The service allows email senders to perform
    a simple check of various sender authentication mechanisms. It is provided
    free of charge, in the hope that it is useful to the email community. While

    ==========================================================
    Explanation of the possible results (adapted from
    draft-kucherawy-sender-auth-header-04.txt):
    ==========================================================

    "pass"
    the message passed the authentication test.

    "fail"
    the message failed the authentication test.

    "softfail"
    the message failed the authentication test, and the authentication
    method has either an explicit or implicit policy which doesn't require
    successful authentication of all messages from that domain.

    "neutral"
    the authentication method completed without errors, but was unable
    to reach either a positive or a negative result about the message.

    "temperror"
    a temporary (recoverable) error occurred attempting to authenticate
    the sender; either the process couldn't be completed locally, or
    there was a temporary failure retrieving data required for the
    authentication. A later retry may produce a more final result.

    "permerror"
    a permanent (unrecoverable) error occurred attempting to
    authenticate the sender; either the process couldn't be completed
    locally, or there was a permanent failure retrieving data required
    for the authentication.

    *******************************************************************

    I found that the DKIM and DomianKeys are not required for sending email to hotmail (is this right?)

    I'm fine to send email to GMail and Yahoo from my smtp server but hot maill is not (even not in the junk)

    Please help!

    Thanks.

    Check for PTR record In some cases, Yahoo and Hotmail reject emails if PTR record is not properly set in mail server and also make sure that your server IP address is not blacklisted from the below mentioned URL:

    This is the result from mxtoolbox

    mxtoolbox.com/SuperTool.aspx?action=blacklist%3a61.47.18.102

    I also tested for ptr and spf record too and it's ok.

    There is a little thing I mentioned that is in the spf test result. -a parameter passed but -all parameter failed the test.

    This is my spf record for mail domain

    mail.absolute.co.th IN TXT "v=spf1 a -all"

    And this is for my domain

    absolute.co.th IN TXT "v=spf1 a mx ptr -all"

    Please check for my spf record.

    Thanks.
