You can do the same with KMail on KDE in the Dolphin file manager by right-clicking a file and selecting Actions > Send To.Дefault clients by definition, though, don't suit everyone.

This launches a compose message window with the selected file listed as an attachment, so you don't have to explicitly launch Evolution in order to compose a message. For example, in Gnome, you can right-click on a file in the Nautilus file manager, select Send To and specify email, to email the file as an attachment to a message. Using the default client does have obvious advantages. KMail is one of the weakest clients in our selection, and we aren't the only ones who think so in the latest Mandriva release it's also been replaced by Thunderbird. Since Evolution now requires Gnome 3 libraries, Ubuntu will switch to Thunderbird as its default email client with the 11.10 release. But the latest releases of these distributions, desktops and email clients has changed the situation somewhat.

Traditionally, this also meant that Evolution was the default on Fedora and Ubuntu and KMail on OpenSUSE and Mandriva, among others. While it's good to have a choice, all distributions and desktops ship with a default email client, so Gnome has Evolution and KDE has KMail. Almost all the clients covered here are cross-platform and can run on any distribution.
