Filter e-mails by GET parameter?

[timmits]

Hi,

Would it be possible to call a url like http://myroundcube?_task=MAIL&[email protected] to only display the emails which come from [email protected]?

Or is it possible to change the PHP code somewhere (preferably as a plugin using a certain hook) to display only the messages coming from  [email protected]?

Thanks in advance for your help!
