Hi, all
On my request for info on the subject of Sendmail on Unix I got
several answers, which I will summarize below. Thanks very much to
Richard Bemrose <rb237_at_phy.cam.ac.uk>, "Richard L Jackson

We use a public domain program called 'smail' on all of our Digital
UNIX
workstations. As 'smail' is a direct replacement for 'sendmail' we
can
simply create a symbolic link:
/usr/sbin/sendmail -> /usr/local/smail/bin/smail

Sorry, we do not use TruCluster.

For our main Cavendish Laboratory mail server we use another public
domain
program called 'exim' which successfully handles high volumes of
input/output email. Plus has a nice X11 monitoring tool.

Digital adds Digital specific capabilities to sendmail. For Digital
UNIX
they support Digital flavors for sendmail 5.x and 8.8.7.

Yes, we are currently using the default Digital UNIX 4.0B supplied
sendmail,
5.65, and process over 300,000+ a day on a single system.

Digital has its own version, we don't run it.
We run the public domain version. I think Digital's is somewhat
behind the public domain version; the Ultrix version was from
the King James branch of sendmail and would not do what we wanted,
especially for the "w" option (TryNullMXList). The Ultrix version
also was not M4 based, which is something we want. Why maintain
a 600+ line sendmail.cf when you can maintain a 30-40 line m4
based file which generates the sendmail.cf?

Depends on what you want to do. We will be moving to TruCluster
this summer. We will probably use a simple configuration with
the main sendmail daemon running on our Alpha 8200.
We may have all the majordomo lists on our Alpha 2100 using a
different service name.

I just checked last week and we handled 110,000 messages last
Wednesday
on our Alpha 8200.
