Hey guys,

I already googled about this (or binged - hehe) and saw that I am not alone with this "error", but I cant find any public solutions for it.

I am using my own domain in combination with outlook.com - I have set up email forwarding from my other freemail accounts (web.de/googlemail/gmx.de) to this outlook.com account.

Now it sometime occurs, that emails are not getting forwarded. I cant see a logic behind this. 95% mails are getting forwarded and 5% are getting rejected.

Then I get a error:

"xxxx@xxxx-de":
SMTP error from remote server after transfer of mail text:
host: xxxxxxxx.pamx1.hotmail.com
5.7.0 (BAY0-PAMC1-F1) Unfortunately, messages from (212.227.15.19) on behalf of (facebookmail.com) weren't sent. The domain's message authentication policy prohibits delivery

Please help me to fix this :(
