- An e-mail agent is a program that is part of the e-mail infrastructure, from composition by sender, to transfer across the network, to viewing by recipient. The best-known are message user agents (MUAs, aka, e-mail clients) and message transfer agents (MTAs, programs that transfer e-mail between clients), but finer divisions exist. More precisely, this is a technical way of referring to functions performed by various programs, considering them as software agents: a given program may perform several functions, but while it is performing a given function (such as message transfer), it is referred to as a message transfer agent. These terms are most often used within internet standards, and technical discussions of e-mail infrastructure, not by end-users. While the individual terms are widely used in internet standards and RFCs, there is no widely used umbrella term for these programs, though such a program may informally be referred to generically as an MxA, 'x' being a wildcard, as the programs are referred to by acronyms of this form, such as MUA and MTA, with 'x' depending on role. E-mail servers are built from one or more software packages, each of which carries out the functions of one or more MxA. (en)
