# joplin-mail-gateway



Simple (bash-based) mail gateway for the open source note taking and to-do application

[Joplin](https://joplin.cozic.net/).



## Rationale



This tool provides a solution for emailing content directly into your Joplin notes.



You may send or forward an email to a dedicated email address. This email is then

automatically delivered to your personal Joplin notes. Attachments (PDFs, Images, ...)

will automatically be included in the note. In addition text is automatically

scanned from images via OCR. This extracted text is added at the bottom of the note so

that it is easily searchable in Joplin. 



## Features



- automatically fetch mails from a certain mail account and add all new mails as Joplin notes

- automatically add mail attachments

- provide tags via mail subject (with #-syntax)

- choose notebook via mail subject (with @-syntax)

- automatically run OCR on images and add text to bottom of note

- automatically add png thumbnails for PDF attachments

- automatically add PDF text part to bottom of note

## Install



1. Clone from github



        git clone https://github.com/manolitto/joplin-mail-gateway.git

        

2. Create a mail directory for incoming mails with following structure:



        mkdir -p ~/joplin-mailbox/new

        mkdir -p ~/joplin-mailbox/cur

        mkdir -p ~/joplin-mailbox/tmp



3. Create a log directory



        sudo mkdir /var/log/fetch-joplin-mails

        sudo chown $USER /var/log/fetch-joplin-mails

        

4. Create a new mail account at your preferred email provider that supports POP3

        

5. Create the configuration file

        

        cp config-sample.sh config.sh

        chmod 700 config.sh 

        

5. Change default configuration by editing `config.sh`



        readonly POP3_USER="your-email-user@your-provider"

        readonly POP3_PW="your-super-secret-pop3-pw"

        readonly POP3_HOST="pop.gmail.com"

        readonly POP3_PORT=995

        readonly DEFAULT_TITLE_PREFIX="Neue Notiz"

        readonly DEFAULT_NOTEBOOK="Import"



7. Test your configuration

        

        ./fetch-joplin-mails.sh  

        

8. Add cron job



        crontab -e



    Add the following line:



        */5 * * * * ~/joplin-mail-gateway/fetch-joplin-mails.sh >>/var/log/fetch-joplin-mails/fetch.log 2>&1           



## Running from a docker container



The gateway can be run from a docker container. The included Dockerfile does everything from installing joplin to 

fetching emails



To setup the docker container :



1. prepare the mail-gateway by editing the `config.sh` file as described above



2. edit the `joplin-config.json` file with your Joplin sync settings. Template files are availables. Simple remove the `.template` extension



3. build the container by running



        docker build . -t joplin_gateway



4. run the container



        docker run -d joplin_gateway
