Hi,

As far I as know (maybe somebody else has other info), you can't directly see when have you replied to a mail. But the fact, that you did, is clearly visible, the subject line should have a small blue icon (see the attached image). You can also enable the Status column, that shows the Read or Replied state of the messages, but I find that redundant.

Regards, Balázs

Thank you for your reply. However, I don't see the blue icon that you mentioned. Is there perhaps some setting that must be turned on for that? I sent myself an email from a different address, then replied to it, but saw no change on the screen.

Also, I don't know what you mean by Status column, but under "View | Toolbars" there is a Status Bar toggle. When it is checked there is a bar at the bottom of the window, but it contains only an icon for "currently online" at the left, and at the right is a button to turn on the "Today Pane".
