Hi Berta,

This mail you just sent came from:

Received: from mo6-p00-ob.smtp.rzone.de (mo6-p00-ob.smtp.rzone.de
 [IPv6:2a01:238:20a:202:5300::8])
 (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
 (Client CN "*.smtp.rzone.de", Issuer "TeleSec ServerPass DE-2" (not verified))

Do you forward mail from your relay to an account on the same email
provider? (Do you forward to the same email address you sent this
mail from?)

If so, then it looks like your email provider has its TLS misconfigured.
(It looks to me like they don't return any certificates at all.)

Here are the certificates in question:
https://www.telesec.de/en/serverpass-en/support/download-area/category/74-telesec-serverpass-de-2

It appears that compatibility with sendmail is not a priority:
https://www.telesec.de/en/serverpass-en/support/root-compatibility

Or perhaps TLS is misconfigured on your sendmail instance.

Or there's some kind of certificate chain error, where your server does
not believe the root certificate that signed the smtp.rzone.de
certificate.

In any case, it's nothing to do with Tor.
