I hate having to re-enter my email settings in a new or reinstalled device.
Secure passwords are particularly painful to transcribe via a phone keyboard,
but it's not just the basic settings. It's also those extras like signature,
disabling notifications and folders that buy you if they're not right. I've set
it all up dozens of times before and will no doubt do it many more.
On my laptop and desktop I have a permanent, version controlled copy of my email
settings that I can apply automatically. Surely you could do the same on
Android/Replicant? I couldn't find any useful information about people doing
this with configuration management tools like Puppet, Salt, Ansible or anything
else so here's my first attempt:
#!/usr/bin/env bash
set -x
# Set the K-9 incoming and outgoing account details via ADB and SQLite3.
#
# Does not yet *create* the accounts, so you still need to click through the
# accounts wizard and enter dummy information.#
#
# K-9 account settings live in an SQLite3 database and have a unique identifier
# for each account. Records in the database look like:
#
# primkey | value
# ba46a4cf-bde0-4d5d-aa6d-9da12a8367df.transportUri | xxx
#
# The transportUri and storeUri represent the server settings and are base64
# encoded, presumably to obfuscate the password.

The idea is that you'd plug in your Android/Replicant phone by USB with ADB
debugging enabled and run the above shell script. I gather that you need to kill
K-9 mail for the settings to take effect (long hold on primary button and close K-9).
Alright, now I'll freely admit that this took quite a bit more time than it
would of to just complete the K-9 settings wizard, but it's the principle that
counts! The great thing about Free Software is that I can have confidence that
I'll be using K-9 for many years to come, so this investment of time is
worthwhile.
I haven't tried creating accounts from scratch. It could be just
generating a UUID identifier and setting [UUID].accountNumber to say 2 for a
third account. Or there might be some place you need to register the UUID.
That's work for another day.
