@DaveRo : thanks again.
Problem not yet solved in fact, but I got you …
A message can be written at 12:00 (time A), sent 2 hours later (time B), get to the initial server 2 minutes later (time C), and then forwarded in a few minutes or more (time D), and then reach you (time E) …
Let’s say an addon, rather than a search in the source code where data is confusing and non-existing eventually, would be a very nice thing … with “date sent” from the initial server to the date and time final server received and date and time received via TB …
These are really important things in some particular instances.
This looks like a Police investigation, but it is not !
So one step ahead is to know how much time it takes between the time it takes usually between hitting the button “send” and the time the initial server gets it !
Can you answer me ?
For the rest, ie initial server and final one, I hope someone will tackle this problem (for POP3 accounts) !
