It was delivered and removed from the queue.

Your mail(1) MUA is not configured (or unable) to look in the place 
where the mail was, in fact, delivered.

Dovecot says it delivered it ...

... and duly reported this success to Postfix, which deleted it from 
the queue as a result.

Judging from your previous post where deliver tried to write to 
/root/Maildir/, I suppose your mail will be found in 
~thufir/Maildir/new/ .

Now Postfix is fine, Dovecot seems to be fine also. Your remaining 
issue is with "mail". If it's old BSD mailx, that is not very 
configurable. Consider other choices, such as mutt, alpine, or 
Heirloom mailx.
