Internet history is full of painful security incidents. We traded in old email client compatibility for features that are more secure and meet modern security requirements.

Exim is a mail-transfer agent (MTA), which can be used in Unixllike operating system. Philip Hazel wrote the first version in 1995 for the University of Cambridge Computing Service's email systems. Exim is available under the GPL and is free to download and modify. Exim is somewhat similar to Smail 3. However, it has diverged from it and now exceeds it in ease-of-use and flexibility. Both follow the Sendmail design model, where one main binary controls all facilities of the MTA. Some consider this monolithic design to be less secure and slower. However, Exim's security record and speed are better than Sendmail. It excels in advanced areas like address routing, queue handling, and testing. Exim does not have a Graphical User Interface (GUI), but some Linux distributions do.

qmail is an efficient, reliable, and simple message transfer agent. Security is not just a goal but a requirement. Users cannot turn off mail delivery, so it needs to be secure. The straight-paper-path philosophy of qmail ensures that a message, once accepted into the system will never be lost. qmail can optionally support maildir, an ultra-reliable new user mailbox format. Maildirs will not be corrupted by a system crash, unlike mbox and mh files. Not only can an NFS client safely deliver mail to a user, but it can also be used by multiple clients at the same time. qmail is much smaller than any Internet MTA. Other MTAs use separate mechanisms for forwarding, aliasing and mailing lists. qmail offers a simple forwarding feature that allows users to manage their own mailing lists.

If you connect via dialup, only the mail server can access this connection. Your workstations don't need their own modems and Internet accounts. The mail server will continue to process mail even if the client workstations have been turned off. This allows functions that rely on a constantly available service such as auto-forwarding and automatic replies.
