I don’t understand at all, there is mailx, and he sends and receives postfix why? And is it still full or cut?

you don't understand correctly. Mailx is the MUA mail client, and postfix is the MTA transport mail agent and it stands behind the fact that you need to deliver the kidney somehow. Let Dade locally.

Then that the collectors of the distribution prefer it. By the way, you seem to have mixed up with procmail. mailx - console mail client, often used in scripts, postfix - MTA, alternative to sendmail
