Mail delivery agent
From Wikipedia, the free encyclopedia
A Mail delivery agent (MDA) is software that delivers e-mail messages after they have been accepted on a server, distributing them to recipients' individual mailboxes.[1]
[edit] Implementation
A mail delivery agent is not necessarily combined with a mail transfer agent (MTA), although on many systems the two functions are implemented by the same program or package. Various MTAs let the postmaster or the user configure which MDA will handle relevant incoming messages.
On Unix-like systems, procmail and maildrop are the most popular MDAs. The Local Mail Transport Protocol (LMTP) is a protocol that is frequently implemented by network-aware MDAs.
