Why does the Read Receipt have the following information:
- The "To:" field is empty.
- The send field has a time/date 9 sec after the read date?
Sent: Monday, 23 January 2023 3:38:53 pm (UTC+00:00) Monrovia, Reykjavik
was read on Monday, 23 January 2023 3:38:42 pm (UTC+00:00) Monrovia, Reykjavik.
This only happen with external address .
Now I have to explain that some only open today a mail send in 2015, but the read receipt say the message was send today.
Inside our organization this issue does happen
