Use the MAIL command in backtrack to send emails

My BT version is backtrack5 R3. use the MAIL command to send an email to the QQ mailbox.

The original installation of mailutils does not display errors, but the QQ mailbox cannot receive emails. At this time, the MAIL command does not contain the-V option. Uninstall mailutils and install BSD-mailx
$ Apt-Get remove mailutils $ Apt-Get install BSD-mailx

Run
