All my outgoing hotmail messages are marked 'This sender failed our fraud detection checks and may not be who they appear to be' by hotmail. Any answers ?

When using Thunderbird to send Hotmail messages, the received E-Mails at the recipient are marked with 'This sender failed our fraud detection checks and may not be who they appear to be'

There is no problem sending from the same machine using direct webmail/outlook.

Outgoing config shown below

Thanks

You need to ask Hotmail what their problem with your mail is.
