The extension of this mail is @yahoo.com, before we can send to this email using our outlook but now we cannot.
Sometimes we can send mail to this email address without a problem, sometimes we are sending mail but we are areceiving mailer-daemon.
not only on this email with extension of @yahoo.com but also other extensions like @hamad.qa which is very important to us.
other email with different email extension do not have any problem, I mean we can send and communicate with them normally.
I contact our internet provider regarding this problem but they send me the below problem(Attached photo).
I hope you can help me with this problem.
Thank you and warm regards,
Joveth Villaviray
