Sendmail is a very popular MTA (mail transfer agent) for UNIX written originally by Eric Allman. Since sendmail is the standard MTA on most UNIX and Linux systems, the Faximum Messaging Server products are designed (but not exclusively tied) to work closely with sendmail.
More information on sendmail may be obtained from the Sendmail company (http://www.sendmail.com/) and the Sendmail Consortium (http://www.sendmail.org/).
O'Reilly and Associates (www.ora.com) have published the definitive book on sendmail, sendmail, 2nd Edition By Bryan Costales & Eric Allman 2nd Edition, January 1997, ISBN 1-56592-222-0 (see http://www.oreilly.com/catalog/sendmail2/).
