Mail Transfer Agents

A Mail Transfer Agent (MTA), or mail router, accepts messages generated by a Mail User Agent, determines a route for delivery, edits the message header as required by the destination and delivery program, and calls the appropriate delivery program to deliver the mail.

You can choose between two Mail Transfer Agents, provided with SCO OpenServer systems, mmdf(ADM) and sendmail(ADMN). The default MTA is MMDF, but you can choose to switch to sendmail either at installation time or subsequently. See ``Changing Mail Transfer Agents''.
