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. Therefore,
a lot of flags are not supported.
The header is limited to 4K and the number of recipients to 100.
Known problems:
Pine uses a lot of sophiticated options to talk to sendmail, and uses batched
SMTP input which is not supported. The solution is to use your mailhub as
smtpserver in pine.conf.
