Updated notmuch to only be available for full-text search. Removed complete afew configuration. Added msmtp as mail sending agent. Added structured neomutt configuration with custom bindings, built for my personal gmail account, without any plaintext passwords revealed, etc. This is a reasonably well working mail setup, which should provide a stable starting point for further refinements. Additionally, added some functionality to `mail-check` script: Allowed user to choose sync target for each run, by passing in mbsync target (group/channel/..) as the argument. Also, allows setting password file to use for script through env var, and made imapfilter location less hard-coded to my system.

# Runs mbsync, with pre-hooks and post-hooks
|
|
# by default, the pre-hook first runs imapfilter
|
|
# and afterwards the post-hook indexes with notmuch.
|
|
#
|
|
# At the very least, you will have to set up a gpg
|
|
# encrypted file containing the password for your
|
|
# remote mailbox. It can be set directly below or
|
|
# through the environment variable
|
|
# `MBSYNC_PASSWORD_FILE` and should point to any
|
|
# gpg decryptable file.
|
|
#
|
|
# To run without invoking any hooks or retry attempts,
|
|
# run `checkmail raw`.
|
|
# this will simply invoke a single isync run on all
|
|
# boxes with the correct config file set.
|
|
#
|
|
# To invoke mbsync for a specific group or channel,
|
|
# simply run it with `checkmail <channelname>` and
|
|
# it will only sync the correspondingly named.
|
|
#
|
|
# To run your own commands as hooks overwrite the
|
|
# environment variables `MBSYNC_PRE` and
|
|
# `MBSYNC_POST`. If you want to not have anything run
|
|
# for either of them the easiest way is to set the
|
|
# corresponding environment variable to true.
|
|
# Be careful which commands you put here since they
|
|
# will be evaluated without any special precautions.
