RoadRunner Email SSL/TLS STARTTLS Encryption does not show up in email header.

So I have my city.rr.com email setup in Thunderbird as;

in: POP3   mail.twc.com   Port 995  SSL/TLS

Out: SMTP  mail.twc.com  Port 587  STARTTLS

And email comes & goes just fine.

However examination of the email headers show NO MENTION

of STARTTLS or TLS, or ESMTPSA.  Emails from other providers do.

In addition, use of CHECKTLS,  a 3rd party .com to check security,

passes just fine for ALL that I tried, ~7,  EXCEPT  RR.

So either:

1) RR just does not document the use of TLS, or

2) It is not working, or

3) I am missing something.

BTW CheckTLS does not send an email, so you can use    xxxxx@actual.name

Any help would be appreciated.

Does this issue only happen in Thunderbird, or can you replicate the issue in another email client?

A friend of mine sent me email using Mozilla 5.0 & Thunderbird  80.9.0 & a gmail address, ESMTPSA & TLS 1.2 on first hop,  no mention of either thereafter.  I was hoping that someone else using roadrunner could check their email header ?

It appears to support TLS via both port 587 and 25:
