 === Additional Notes
 1. Long time has passed, and it seems that all the referenced tickets have
 been closed.
 2. Regardless of the timezone selected, emails are always being sent in
 UTC time. Job for the MUA to present the right time for the user based on
 the timezone configured in the client.
 3. Considering this variables, I'm closing this as `worksforme`. If new
 scenarios happen to arise, please provide some screenshots, and reopen
 this ticket witch such information. Also please provide raw email data
 along with the shots.
