Hi,
When I try to send a mail to a given email address I almost immediately receive the following error:
Subject: Delivery Status Notification (Failure)This is an automatically generated Delivery Status Notification. Delivery to the following recipients failed.
xxxx@xxxxx.com
(email hidden for privacy reasons)
No error code whatsoever indicating why the mail was not sent.
The recipient confirms receiving mails from other source with no problem.
How can I know why this specific address fails ? I am sending from the outlook web site, so it's not a problem of my mail client configuration.
It really looks like outlook.com is filtering this email address out.
Thanks in advance.
Best regards
