This is already possible now, it can be achieved by adjusting the account options so that your sent folder is set to be the configured sent folder. WebMail will then autoamticlaly display the To instead of the from.
Is this possible without enabling the save-to-sent option because otherwise when I use my IMAP connection on outlook, I get 2 copies in the sent folder.
We use Outlook 2003 in the office here but the option to contorl this is located in Options, Preferences Tab and click on the "Email Options..." button.
