Sorry. Thunderbird is not an email provider.

''<p>Werner Oppermann [[#question-1477139|said]]</p>'' <blockquote>Can I have an E-Mail-Adress from Mozilla? </blockquote> Just to be sure. There is no direct one on one support by email, chat or phone whether from Mozilla or Thunderbird devs. The general public cannot get @mozilla.org email addresses as they are only provided to people who work for Mozilla in a capacity that warrants getting one. When they leave they have to give up the email address. Even Mozilla does not provide one on one support for their Firefox web browsers. They do have direct ticket support here but only for the subscription based products like Mozilla VPN because you paid for that as part of the subscription.
