MUA = Mail User Agent, a.k.a. an email client: a program you use to compose and read email. Apple Mail, Microsoft Outlook, Mozilla Thunderbird, old school programs like mutt, ELM, MH, /bin/mail or Mail/mailx. O course for many of us our MUA is not a standalone program but a web app running in a browser (e.g. GMail), but that still counts.
The MUA is specifically distinguished from the Mail Transfer Agent (MTA) which is responsible for actually getting the email where it needs to go; Microsoft Exchange and sendmail are MTAs.
