Version: (using KDE 3.5.9) Currently you have to enter valid address. Like _@_ I see no gain in forcing user to enter something instead of nothing. It seems like taking care of user but really is limiting user. So instead of dialog "invalid adress......." [OK] please put the dialog Yes/No so the user can get back and correct the address or ignore the warning. Of course correcting should be default button.
Thank you for your feature request. Kmail1 is currently unmaintained so we are closing all wishes. Please feel free to reopen a feature request for Kmail2 if it has not already been implemented. Thank you for your understanding.
Instead of creating a new feature request, please confirm here if the wishlist is still valid for kmail2.
