I wanted to sign up to anki.
But it seems Anki cannot send the verification email to me. The verification page ( says: "Email Failed. We were not able to deliver an email to your mail provider."
My provider is T-Online, and I checked the address many times to be correct.
What can I do to sign up?
Best regards,

    Please contact your email provider and let them know they are blocking our email. This is the message they are returning:

    " - A problem occurred. (Ask your postmaster for help or to contact [email blocked] to clarify.) (BL)"

    They may or may not be willing to help you - you may find it easier to sign up with a different email address if you have access to one.

    Hi Damien,
    thanks a lot! I will try to convince them, but as you wrote ("They may or may not be willing to help you") I would rather guess that they may not be willing...
    So I guess I will have to sign up at another provider.
    Just one question: This verification mail is sent from "" ?
    Thanks again,

    Hi Damien,
    it seems that they could be willing to help me at They said they would need the IP address from which the email was sent since they would not block email addresses. Could you tell me the IP address from which this email was sent?
    Thanks in advance!

    Hi Damien,
    thanks for your help! At t-online, they say I must not do anything. Only the postmaster at would be allowed to get information about blocked IP addresses.
    So I am going to sell my data and soul to google and try it with a gmail address.
    Thanks again for your help!

    No problem, it looks like you were able to verify your address using the new account?
