Lo siento... la verdad es que sé que es una lata esto de los mensajes en blanco para los que usamos el webmail de gmail. Deberíamos usar otro cliente...

Pero parece que el uso de chown sólo se permite al root. Por seguridad, supongo :-?

Aquí explican algo...
*** http://www.unix.com.ua/orelly/networking/puis/ch05_07.htm
(...) In earlier versions of UNIX, all users could run the chown command to change the ownership of a file that they owned to that of any other user on the system. This let them "give away" a file. The feature made sharing files back and forth possible, and allowed a user to turn over project directories to someone else.
Allowing users to give away files can be a security problem because it makes a miscreant's job of hiding his tracks much easier. If someone has acquired stolen information or is running programs that are trying to break computer security, that person can simply change the ownership of the files to that of another user.
If he sets the permissions correctly, he can still read the results. Permitting file give-aways also makes file quotas useless: a user who runs out of quota simply changes the ownership of his larger files to another user. Worse, perhaps, he can create a huge file and change its ownership to someone else, exceeding the user's quota instantly. If the file is in a directory to which the victim does not have access, he or she is stuck. ***
Interesante :-)
MUY interesante. - -- Saludos Carlos E.R. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAkj+R28ACgkQtTMYHG2NR9W6ugCfW4Igienz6GA7Z0RW1k4prPX7 newAn0iRE8vqcGZ62LH806jMDbE1ob/n =VrrR -----END PGP SIGNATURE-----
