Description Pedro Sampaio 2021-08-18 15:14:21 UTC 
The STARTTLS option of SMTP is ignored, when "Server requires authentication" is not checked. In this case kmail will send any mail in cleartext.

Comment 1 Pedro Sampaio 2021-08-18 15:14:34 UTC 
Created kmail tracking bugs for this issue:

Affects: fedora-all [bug 1995181]
Comment 2 devthomp 2021-08-24 01:27:42 UTC 
I'll do some more digging but according to the manifest kdepim has been removed from RHEL (since 2019-09-10).
Comment 4 devthomp 2021-08-31 13:41:45 UTC 
kmail is susceptible to a confidentially leak if "Server requires authentication" not checked in UI.
The issue in a nutshell is this could lead to information not being encrypted that otherwise would be.

analysis is complete, trackers have been filed.
Closing.
