Purpose and value: This is sSMTP, a program that replaces sendmail on workstations that should send their mail via the departmental mailhub from which they pick up their mail (via pop, imap, rsmtp, pop_fetch, NFS... or the like). This program accepts mail and sends it to the mailhub, optionally replacing the domain in the From: line with a different one.

WARNING: the above is all it does. It does not receive mail, expand aliases or manage a queue. That belongs on a mailhub with a system administrator. The man page (ssmtp.8) and the program logic manual (ssmtp_plm) discuss the limitations in more detail.

It uses a minimum of external configuration information, and so can be installed by copying the (right!) binary and an optional four-line config file to a given machine.

Type of systems supported: Berkeley-derived, or ones otherwise using /user/lib/sendmail as a mail transfer agent. In use on SunOS 4.1.1, NextStep 2.x/3 and Ultrix 4.2, tested briefly on AIX 3.2 and RISCos. Tested by others on DG U/X 5 and SVR4.

Dependencies: External: Berkeley sockets and supporting libraries.

Known limitations: This is not a complete sendmail. It is only a program to post mail to a mailhub for people who don't want a complete sendmail.
