Thus, I created a script that let you to send an e-mail attaching the files selected in caja. It also has options to compress these files into .zip, .rar, .tar.gz, and tar.bz2.
It is a good workaround until the thunderbird plugin is ported to caja-sendto.
You just need to download the file and copy it to the folder ${HOME}/.config/caja/scripts/
To use, select the files in caja you want to send, right-click->scripts->Send files using Thunderbird
Every comment and suggestion are welcome
