Personal sieve scripts collection

This repository is intended to store and organize my personal sieve scripts. Since their complexity grows every day I decided to organize them in a better way: split them into multiple files while versioning via git. Using the below-described git-hook, at each git commit the scripts are automatically uploaded to the mail-server.

Requirement

You need sieveshell installed. Good news for secbox users, in case you are running secbox >= 1.10 and secbox-image >= 2.7, then you already have sieveshell available. You can double-check with the following commands:

> secbox -v
script     :  secbox                                                       v.1.9
image      :  non_public/maintenance/security/container/containers/secbox  v.2.7
container  :  secbox                                                       running
> which sieveshell
sieveshell: aliased to secbox --no-tty sieveshell

How to use

1. The manual way

   I store my credentials (application password) in the local wallet, which I can access via D-Bus using the secret-service protocol. The following functions are intended to collect username and password for the secret service provider (keepassxc for me).

   unlock_wallet() {
       echo "check the explanation attribute ;)" | secret-tool store --label="dummy-entry" explanation \
       "Because of quirks in the gnome libsecret API, a dummy entry needs to be stored in order to \
       guarantee that this keyring was properly unlocked. More details at http://crbug.com/660005 and \
       https://github.com/keepassxreboot/keepassxc/issues/4443"
   }
   
   get_user() {
       unlock_wallet
       secret-tool search client sieveshell workstation wintermute 2>&1 | \
       grep -E "^attribute\.UserName" | \
       cut -d " " -f3
   }
   
   get_pass() {
       unlock_wallet
       secret-tool search client sieveshell workstation wintermute 2>&1 | \
       grep -E "^secret" | \
       cut -d " " -f3
   }

   From inside the repo work-tree, I run the following command to upload the *.sieve scripts to the mail-server. This can be hooked into the git client in a way that it automatically updates the sieve scripts at every new commit (see below).

   find $(git rev-parse --show-toplevel) -type f -name "*.sieve" -printf "put %p %f\n" | sort -nr | \
   sieveshell --user $(get_user) \
           --passwd $(get_pass) \
           --use-tls \
           --port 4190 \
           imap-int.suse.de

2. The git way

   The hook is already provided within this repository, I strongly suggest you leverage conditional includes (cool beans) in your gitconfig. This will be as easy as appending the following lines to your ~/.gitconfig (e.g. mine):

   ; Only include if the repository is sieve-susede
   [includeIf "gitdir:~/Workspace/sieve-susede/.git"]
           path = ~/Workspace/sieve-susede/.githooks/sieveshell.gitconfig
   

   ^{* Do not forget to adjust the paths in the above snippet.}

   You can now jump into your local repository copy, make your changes and commit.

---

After the first run, ensure that 00-Init.sieve is activated. Or you can activate it after your first upload running:

echo "activate 00-Init.sieve \n list" | \
sieveshell --user $(get_user) \
        --passwd $(get_pass) \
        --use-tls \
        --port 4190 imap-int.suse.de

And check for: 00-Init.sieve <<-- active.
