  I've noticed an increasing use of the terms MTA and Mail 
Transport Agent lately to mean MUA.  

  This is inaccurate, and ultimately will lead to 
misunderstandings.  For clarification, an MTA is the mail 
server software... the daemons that send and receive all 
that internet e-mail behind the scenes.  Unless you are a 
'nix guru, it is highly unlikely you ever have any 
interaction with the MTA.

MTA - Mail Transport Agent; sendmail, qmail, etc.
Sends and receives e-mail at the server level.

MDA - Mail Delivery Agent; mail, procmail, etc.
Usually only used on multi-user systems.  Sendmail can act 
as both MTA and MDA, but on systems with dedicated MTA's, an 
additional MDA may be necessary.

MUA - Mail User Agent; Arachne, Netscape, PINE, etc.
This is the software used to retrieve, send, read, and 
compose e-mail at the user level.  99% of people using 
e-mail will never know anything more about e-mail than what 
they know about their MUA.
