MTA (Message Transfer Agent)
Note: Many topics at this site are reduced versions of the text in "The Encyclopedia of Networking and Telecommunications." Search results will not be as extensive as a search of the book's CD-ROM.
In the X.400 Message Handling System developed by the CCITT (now the ITU), an MTA is like a post office through which messages are exchanged between systems. The MTA provides store-and-forward services. See "X.400 Message-Handling System."
