Everytime i will change the Email from my to Another email it Gives me this Message

-> Mail Delivery Failed : returning message to sender.

I try it now for 10 times, but everytime same.

Anyone knows problem?

It means that it is an invalid e-mail address. Make sure you have the correct recipient and try sending the message again.

Make sure to post questions like these or any other general question in the General Help section.

Its 100% the right email, got this problem @other acc too, but 2 days later it works.

You are probably the victim of email address spoofing - spammers are putting your email address in the "From" field of the messages they are sending and you are receiving the bouncebacks, just as you would get letters returned by the post office if someone were putting your street address on the envelope as a return address. Since your email account and computer are completely uninvolved with the shenanigans, scanning won't help and there is really nothing you can do about this except wait it out (spammers usually abandon an address pretty quickly) or change your email address.

If your contacts are receiving the spam, then your account was compromised and you would need to take additional steps besides changing your password in order to re-secure your account.

Be sure to run CCleaner, Avast, Malwarebytes and have your Firewall on.

Its 100% on the Mail, recieved all messages , /Mail Acc test too...

Oh man... everytime the same.^
