This wiki describes a basic Debian install of paclink-unix that will work with most e-mail clients. If you are installing paclink-unix on a machine with no keyboard or display then you will use a command line mail client like mutt. If the install is to a 'regular' linux box with keyboard & screen I'm going to assume you are using Thunderbird email client or something that allows configuring a Unix movemail account. For some background on how e-mail works I found this link helpful: A short introduction to the notorious MxA bunch.

• MTA: Mail Transfer agent

While I have installed & config'ed sendmail, the package, I think it is easier to config postfix for the MTA. There is usually some confusion over sendmail. There is sendmail the package & sendmail the program which can be found in any of these Debian packages:

nbsmtp , smail, nullmailer, exim4-daemon-heavy, masqmail, courier-mta, msmtp-mta , esmtp-run, ssmtp, sendmail-bin, xmail, postfix, exim4-daemon-light.

• MUA: Mail user agent

You do not need to install an imap or pop3 server to get paclink-unix to work. For your initial install I advise against doing this. After you have confirmed that paclink-unix is working with just an MTA only then would I embark on configuring an imap or pop3 server. Why would you want an imap or pop3 server? One of the ways I use paclink-unix is from my Android Nexus tablet I use the Android K-9 Mail program & invoke the wl2k transport programs via a web interface. That code is in the paclink-unix cvs tree under webapp. So the short answer is that you can support more mail clients with an imap/pop3 interface than a movemail interface. Mail clients that support the movemail interface include Thunderbird, mutt & most webmail clients such as neomail.
