My desktop system has sporadically been freezing up on me, even as I try to swap out various parts to figure out what’s causing my grief. I’m finally giving in and accepting that it’s a 9 year-old system with a mixture of 1-year and 7-year parts. It’s wasted too much of my time. So I’ll start figuring out what to do for a replacement (yay tax deductions for work).
To be practical, I need to move some things to not depend on it until I get the replacement. First on the list is all of my mail folders which are usually available via the IMAP server (running
courier-imap) on my desktop system. The little Mac Mini on the corner of my desk is probably the answer; having just upped its memory I figure it’s ready for the task.
Luckily David Bondes in Sweden has spelled out most of the steps to get the Courier IMAP server to build and run under OS X. Elsewhere, I found ttya.net with a more complete and up-to-date set of instructions about how to make authentication work.
The best discovery is MacPorts (formerly DarwinPorts), which uses a FreeBSD-style ports system to make it really easy to build and install random software to run on the system. As you’re about to see, though, the efforts of the MacPorts version of courier IMAP needs some further polishing.
The steps I did:
- Install MacPorts.
- Downloaded and installed everything with the fun command
sudo /opt/local/bin/port install courier-imap
which did all of: db44, courier-authlib, zlib, openssl, and courier-imap.
YES(may actually be irrelevant)
- The command the script said to run to make it start up when we boot:
sudo launchctl load -w /Library/LaunchDaemons/org.macports.courier-imap.plist
sudo cp /opt/local/etc/authlib/authdaemonrc.dist /opt/local/etc/authlib/authdaemonrc
- Following the instructions from ttya.net, put entries in a new file
that look like
username uid=511|gid=511|home=/Users/username|shell=/bin/bash|systempw=*|gecos=Real Name
userdbpwto generate the hash that replaces the * for
systempw. Then run
makeuserdbto convert the userdb into a DB4 database. Make sure you have a TAB character, not a space, between
sudo mkdir -p /opt/local/var/spool/authdaemon
sudo /opt/local/sbin/authdaemond start
- I also had to do this to make it generate the SSL key:
sudo sh /opt/local/share/courier-imap/mkimapdcert
- And the command to make it start now without having to reboot:
sudo /opt/local/etc/LaunchDaemons/org.macports.courier-imap/courier-imap.wrapper start
- I didn’t have to run
maildirmake Maildirbecause I’m syncing mine over en masse.
authdaemonrc to have
authmodulelist be just
And it works! The manual bits after
port did its deeds were pretty tedious, and the majority should be able to be done as part of the
Portfile included with
courier-authlib. It should also be possible to use the DirectoryServices API to make an ‘authosx’ sort of module to not require the userdb hack. (That file needs to be regenerated any time someone changes their password, for instance.)
That’s ok—at least I’ve let go of a major depencency on my dying desktop system.
