lei + thunderbird recipe

This thread is inspired by Ævar's recipe [1] and Josef Bacik's recipe [2].

As I know that GMail have issues regarding delayed ML message delivery, I go trying to use lei to fetch ML messages into Thunderbird.

After installing public-inbox (I have to build from public-inbox.org sources because there isn't yet official Debian/Ubuntu packages), I begin fetching Git ML messages up until 18 days ago (within public-inbox sources directory):

	lei q -o "mboxrd:mbox/git.mbox" -I https://lore.kernel.org/git
	-t 'a:git@vger.kernel.org AND rt:18.days.ago..'

Why mboxrd instead of Maildir? Because from formats within Mbox family, Thunderbird uses mboxrd format.

After initial fetching, I update the mbox by:

	lei up mbox/git.mbox

To automate this, I write simple script:

``` #!/bin/bash

# replace with directory of your Thunderbird profile THUNDERBIRD_LOCAL=$HOME/.thunderbird/1a14l7jo.default-release/Mail/"Local Folders" MAILDIR=$HOME/public-inbox/mbox # add more mboxes name here if you have one MBOXES="git"

for m in $MBOXES; do
	echo $m &&
	$HOME/public-inbox/local/bin/lei up $MAILDIR/$m.mbox &&
	cp $MAILDIR/$m.mbox "$THUNDERBIRD_LOCAL"/
done
```

and then set up systemd timer comprising of user service unit:

``` [Unit] Description=Lei update After=network.target

[Service] Type=oneshot ExecStart=/home/bagas/.bin/lei-up Restart=on-failure

[Install] WantedBy=default.target ```

and user timer unit that updates the mbox every 12:00 and 18:00:

``` [Unit] Description=Lei update timer

[Timer] OnCalendar=*-*-* 12:00:00 OnCalendar=*-*-* 18:00:00 Persistent=true AccuracySec=1s

[Install] WantedBy=timers.target ```

To fire up the timer, I simply do `systemctl --user enable lei.timer`.

Hope this will be useful.
