Spam mail sorunu

Selam arkadaşlar.

Yaklaşık 1 haftadır microsoft tabanlı maillere (hotmail,msn,windowslive) mail gönderemiyoruz. CBL ve spamhouse' da devamlı blackliste düşüyoruz. Remove etsemde birkaç gün içinde yeniden karalisteye alınıyoruz bu iki yerde. Şuan ttnet avea gibi kurumsal firmalarada mail atamıyorum. Gönderdiğimiz mailler direk postmaster olarak geri dönüyor. Aldığım hatayı aşağıda belirtiyorum. Lütfen konuyla ilgili bir çözüm yolu sunabilirseniz sevinirim. 1 haftadır yapmadığım şey kalmadı. Microsoft senderıt spf kaydınıda oluşturdum. Mail sunucumuz Fortimail firewall fortigate 310B.
