Sendmail lacks the configurability of Exim.

I can refuse connections if the sender's host name resembles a home
Internet connection (contains dyn* static nnn-nnn-nnn-nnn or
nnn.nnn.nnn.nnn or is on the list of home-type hosts such as
*dsl.bell.ca   etc. etc.)

I refuse connections when the HELO / EHLO does not resolve to the
sender's IP address, for example

Sender's IP : 62.25.80.157 = mail1.bemta105.messagelabs.com
Host name   : mail1.bemta105.messagelabs.com = 62.25.80.157
HELO name   : server-12.bemta-105.messagelabs.com = no IP address
Date        : Tuesday, 11:04, 12 August 2014, (+01:00)

Sender's IP : 202.94.83.220 = 202-94-83-220.infra.usd.ac.id
Host name   : 202-94-83-220.infra.usd.ac.id = 202.94.83.220
HELO name   : ASRI-PC = no IP address
Date        : Wednesday, 06:16, 13 August 2014, (+01:00)

I can restrict sending to some email addresses to white-listed senders.

I can get rid of pests by rejecting with a bounce message 'the
recipient's mail box is full'.

I can run a basic mailing list, within Exim, without having to use
Mailman.

Just a few bits of basic care can dramatically restrict, if not
virtually stop, spam and the inevitable viruses sent in spam.


I like Exim because it works well for me and it is reliable.

What is really needed is a Plain Man's Guide to basic mail server
operation. Describe the principles and how they are implemented on one's
chosen mail server. Easy task to do, but I lack the time.
