[MASOCH-L] failure notice - Yahoo - Voltou

[Ademir Costa Peixoto]

Prezados,


    Achei que tivesse resolvido com o fato do PTR estar diferente do MX.
    Vejam os telnets abaixo:

    Ou seja: Aleatoriamente ele aceita nossos e-mails. Alguém já viu algo 
assim ?

    Pelo site:
    http://www.mxtoolbox.com/SuperTool.aspx?action=mx%3a187.73.49.9 
reporta 1 erro de FQDN mas acho que é bug do site.


    Pelo site:
    http://www.intodns.com/tellecom.com.br    tudo está perfeito.



    Alguma dica de onde começar a garimpar ?

    PS:
    Please refer to http://help.yahoo.com/help/us/mail/defer/defer-06.html
    Já preenchi o formulário umas 5 vezes.

    Pelo Smart Network Data Services da Microsoft está tudo OK e com as 
redes cadastradas (somos ASN) e não constam blacklists no ip do servidor.


    Ats,
