I’m puzzled by K-9 Mail’s display of incoming messages with respect to Date Sent and Date Received. This regularly causes me (and I’m sure others) a lot of confusion. I suspect there are different technical reasons for inconsistent behavior depending on the email service and protocol, so I’ll start with the problem as manifest in an Outlook account (for work).
As an example, yesterday morning, a colleague scheduled a message to be sent today.* I received it this morning, but in K-9 Mail, it shows up under yesterday’s date. The message was a reminder about an event today, so seeing yesterday’s date on the message made me think I missed the event!
In this case, it would make more sense if K-9 Mail used the date the app received the message rather than the date the sender set up the scheduling.
Is this a bug?
Is there an option to choose which date is used in the inbox?
*I believe the desktop versions of Outlook have allowed scheduling when to send email for some time, but this feature has recently been added the Outlook on the web, so it’s seeing more use now.
