Timestamp on e-mails....

I am importing e-mails from my server using IMAP but all of the e-mails have a timestamp of right now, as in the time I am importing them. On the server they show up as the original received time. Is there any way to change the time shown to when the message was actually received?

Nevermind, I got it figured out. For those of you in the future with this problem I added the column “Sent” instead of received.
Seems a little backwards to me but oh well.
