As Thunderbird as enabled "encrypted" subjects by default with 78
and additionally did not offer a way to disable this initially, 
it created a number of real world examples.

Thunderbird forced this change on users, according to this
there is only a hidden (expert) setting to disable it since 78.5.1.

Mentioned drawback:
 * Breaks filtering for the using company.
   " It's very important for mail filtering rules to be able to read the
      subject without opening the mail first."
