Python EML parser library
Project description
eml_parser serves as a python module for parsing eml files and returning various information found in the e-mail as well as computed information.
Extracted and generated information include but are not limited to:
- attachments
- hashes
- names
- from, to, cc
- received servers path
- subject
- list of URLs parsed from the text content of the mail (including HTML body/attachments)
Please feel free to send me your comments / pull requests.
For the changelog, please see CHANGELOG.md.
Installation:
pip install eml_parser[filemagic]
:warning: Note: If you don't want to / cannot use file-magic (e.g. if you are using python-magic), install via:
pip install eml_parser
Known Issues
OSX users
Make sure to install libmagic, else eml_parser will not work.
Python <=3.7.4 "rare header field parsing issue"
It has been reported (in #60) that there are parsing issues in some particular cases which seem to be caused by a bug in the email module of the Python standard library. At least versions <=3.7.4 are affected.
Python versions >=3.7.11 are not affected. If you do get KeyError exceptions on header field parsing, you should consider upgrading to a more recent version of Python.
-> Please open an issue if the error persists after upgrading.
Example usage:
import datetime
import json
import eml_parser
def json_serial(obj):
if isinstance(obj, datetime.datetime):
serial = obj.isoformat()
return serial
with open('sample.eml', 'rb') as fhdl:
raw_email = fhdl.read()
ep = eml_parser.EmlParser()
parsed_eml = ep.decode_email_bytes(raw_email)
print(json.dumps(parsed_eml, default=json_serial))
Which gives for a minimalistic EML file something like this:

"body": [
{
"content_header": {
"content-language": [
"en-US"
]
},
"hash": "6c9f343bdb040e764843325fc5673b0f43a021bac9064075d285190d6509222d"
