OSX, mail.app, and dovecot

OSX's mail.app can't seem to read files in /var/mail sent by, you guessed it: OSX itself. So, one can install dovecot from MacPorts and do a little configuration. First, set up a self-signed cert.

sudo mkdir -p /opt/local/etc/ssl/certs
sudo mkdir -p /opt/local/etc/ssl/private
sudo openssl req -new -x509 -nodes -config dovecot-openssl.cnf -out /opt/local/etc/ssl/certs/dovecot.pem -keyout /opt/local/etc/ssl/private/dovecot.pem -days 3650

Then, copy the example configuration

sudo cp /opt/local/etc/dovecot/dovecot-example.conf /opt/local/etc/dovecot/dovecot.conf

and make minor mods to dovecot.conf

sudo cp /opt/local/etc/dovecot/dovecot-example.conf /opt/local/etc/dovecot/dovecot.conf
sudo rcsdiff /opt/local/etc/dovecot/dovecot.conf

And fire dovecot up

sudo port load dovecot
