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.
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 [email protected]
Any help would be appreciated.
