Hello,

I, a little frustated user of your community opens again a discussion about the Backscatterer problem with Outlook.com's Out of office reply as discussed here in this closed topic: http://answers.microsoft.com/en-us/windowslive/forum/email/diagnostic-code-smtp554-571-service-unavailable/61c82a91-ff88-4998-a3e4-aa495b001b4f 

The problem is a problem of you with the Outlook.com's Out of office reply. Yes, I have problems with that, but I am here to help you Microsoft to fix a problem with your Outlook.com emailservers.

And let we have a deal. No messages via Private Messages, everything via this open forum. So everyone can get his benefit with the information.

BeBelow my email I sent to you when I finally reached someone of the Hotmail Sender Support:

(moved to the private message area for privacy purposes)

So there you have all information. If you need more information about the problems Outlook.com's emailserver has with Spamcop/Backscatterer and so forth, dont hesitate to ask me.

I have stated it in my email. The solution is maybe a Little Small Configuration Setting in your emailservers config...

Thank you in advance, and I am wondering if I'll ever do get support now.
