Now that email is inbound and being stored, now I need a mechanism of accessing it remotely. In the past I used courier-imap. Lately, the in-thing appears to be Dovecot. It appears to be fast, simple, and effective.
The Debian package repository is not really up-to-date, so I'll have to download the source and compile. The source is Dovecot v1.2.1. I usually put it into /usr/src and 'tar -zxvf ' it to expand the source. For configuring and compiling, I used:
./configure \ --sysconfdir=/etc/dovecot \ --with-storages=maildir \ --localstatedir=/var/local/dovecot \ --with-rundir=/var/local/dovecot/run \ --with-statedir=/var/local/dovecot/state \ --with-pam make make install
A user dovecot needs to be added with 'useradd -r dovecot'.
