mail-parser

Overview

mail-parser is not only a wrapper for email Python Standard Library. It give you an easy way to pass from raw mail to Python object that you can use in your code. It’s the key module of SpamScope.

mail-parser can parse Outlook email format (.msg). To use this feature, you need to install libemail-outlook-message-perl package. For Debian based systems:

$ apt-get install libemail-outlook-message-perl

For more details:

$ apt-cache show libemail-outlook-message-perl

mail-parser supports Python 3.

Description

mail-parser takes as input a raw email and generates a parsed object. The properties of this object are the same name of RFC headers:

  • bcc
  • cc
  • date
  • delivered_to
  • from_ (not from because is a keyword of Python)
  • message_id
  • received
  • reply_to
  • subject
  • to

There are other properties to get: - body - body html - body plain - headers - attachments - sender IP address - to domains - timezone

To get custom headers you should replace “-” with “_”. Example for header X-MSMail-Priority:

$ mail.X_MSMail_Priority

The received header is parsed and splitted in hop. The fields supported are: - by - date - date_utc - delay (between two hop) - envelope_from - envelope_sender - for - from - hop - with

mail-parser can detect defect in mail: - defects: mail with some not compliance RFC part

All properties have a JSON and raw property that you can get with: - name_json - name_raw

Example:

$ mail.to (Python object)
$ mail.to_json (JSON)
$ mail.to_raw (raw header)

The command line tool use the JSON format.

Defects

These defects can be used to evade the antispam filter. An example are the mails with a malformed boundary that can hide a not legitimate epilogue (often malware). This library can take these epilogues.

and install mail-parser with setup.py:

$ cd mail-parser

$ python setup.py install

or use pip:

$ pip install mail-parser

Usage in a project

Import mailparser module:

import mailparser

mail = mailparser.parse_from_bytes(byte_mail)
mail = mailparser.parse_from_file(f)
mail = mailparser.parse_from_file_msg(outlook_mail)
mail = mailparser.parse_from_file_obj(fp)
mail = mailparser.parse_from_string(raw_mail)

Then you can get all parts

mail.attachments: list of all attachments
mail.body
mail.date: datetime object in UTC
mail.defects: defect RFC not compliance
mail.defects_categories: only defects categories
mail.delivered_to
mail.from_
mail.get_server_ipaddress(trust="my_server_mail_trust")
mail.headers
mail.mail: tokenized mail in a object
mail.message: email.message.Message object
mail.message_as_string: message as string
mail.message_id
mail.received
mail.subject
mail.text_plain: only text plain mail parts in a list
mail.text_html: only text html mail parts in a list
mail.to
mail.to_domains
mail.timezone: returns the timezone, offset from UTC

Usage from command-line

If you installed mailparser with pip or setup.py you can use it with command-line.

These are all swithes:

usage: mailparser [-h] (-f FILE | -s STRING | -k)
                   [-l {CRITICAL,ERROR,WARNING,INFO,DEBUG,NOTSET}] [-j] [-b]
                   [-a] [-r] [-t] [-dt] [-m] [-u] [-c] [-d] [-o]
                   [-i Trust mail server string] [-p] [-z] [-v]

                        Extract a reliable sender IP address heuristically
                        (default: None)
  -p, --mail-hash       Print mail fingerprints without headers (default:
                        False)
