Email Handler Attach

Python Script - Email Handler Attach

This is a specific script that redirect huge attach from an email to another email with low limit attach size. The script does compress on pdf files with they are more than specific size. I am still devolpment but for me needs it is working great

How It Works

The script goes through all email message that has LABEL=PROCESSAR from email account(FROM_ADDR) and then process all attachs and resend to another account(TO_ADDR).

Requirements

• ghostscript
• python3
• python library: unidecode

Installation

First you have to install ghostscript and library unidecode

apt-get update && apt-get install -y ghostscript
pip3 install unidecode

Then just execute app.py

git clone https://github.com/dboc/email_handler_attach.git
python3 app.py

or ...

You could make a container image and run it

git clone https://github.com/dboc/email_handler_attach.git
docker build -t YOUR_REPORSITORY/YOUR_NAME_IMG .
docker push YOUR_REPORSITORY/YOUR_NAME_IMG
# docker run with enviroment variables seet config set

Config

To fit your enviromment and needs, you must change the default envoriments in app.py or set then.

...
GC_BIN = getenv('GC_BIN', 'YOUR_GHOSTSCRIPT_BIN_PATH')
PATH_ATTACHS = getenv('PATH_ATTACHS', 'YOUR_PATH_ATTACHS')
HOST_SMTP = getenv('HOST_SMTP', 'YOUR_SMTP_HOST')
HOST_IMAP = getenv('HOST_IMAP', 'YOUR_SMTP_IMAP')
USER = getenv('USER', 'YOUR_USER')
PSS = getenv('PSS', 'YOUR_PSS')
FROM_ADDR = getenv('FROM_ADDR', 'YOUR_FROM_ADDR')
TO_ADDR = getenv('TO_ADDR', 'YOUR_TO_ADDR')
SRCH_STRING = getenv('SRCH_STRING', 'X-GM-RAW in:YOUR_LABEL')
...

Usage example

Change enviroment variables in app.py.

...
GC_BIN = getenv('GC_BIN', r'C:\Program Files\gs\gs9.27\bin\gswin64c.exe')
PATH_ATTACHS = getenv('PATH_ATTACHS', path.dirname(path.realpath(__file__)))
HOST_SMTP = getenv('HOST_SMTP', 'smtp.gmail.com')
HOST_IMAP = getenv('HOST_IMAP', 'imap.gmail.com')
USER = getenv('USER', 'user@gmail.com')
PSS = getenv('PSS', '123456')
FROM_ADDR = getenv('FROM_ADDR', 'user@gmail.com')
TO_ADDR = getenv('TO_ADDR', 'dest@hotmail.com')
SRCH_STRING = getenv('SRCH_STRING', 'X-GM-RAW in:PROCESSAR')
...

Then execute:

python app.py

After that you would see the output:
