E-Mail mit Dateianhang über SMTP in Python senden

English Deutsch

Dieses Beispiel zeigt, wie man in Python eine E-Mail mit einem Anhang sendet, wobei der Anhang aus einer Datei auf dem Dateisystem gelesen wird:

send_email_attachment.py
#!/usr/bin/env python3
import smtplib
import mimetypes
from email.message import EmailMessage

# Nachricht erstellen und Textinhalt setzen
msg = EmailMessage()
msg['Subject'] = 'This email contains an attachment'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
# Textinhalt setzen
msg.set_content('Please see attached file')

def attach_file_to_email(email, filename):
    """Datei mit filename an E-Mail-Nachricht anhängen"""
    with open(filename, 'rb') as fp:
        file_data = fp.read()
        maintype, _, subtype = (mimetypes.guess_type(filename)[0] or 'application/octet-stream').partition("/")
        email.add_attachment(file_data, maintype=maintype, subtype=subtype, filename=filename)

# Dateien anhängen
attach_file_to_email(msg, "myfile.pdf")

def send_mail_smtp(mail, host, username, password):
    s = smtplib.SMTP(host)
    s.starttls()
    s.login(username, password)
    s.send_message(mail)
    s.quit()

send_mail_smtp(msg, 'smtp.my-domain.com', '[email protected]', 'sae7ooka0S')

Die Hilfsfunktionen in diesem Code sind:

email_utils.py
import smtplib
import mimetypes

def attach_file_to_email(email, filename):
    """Datei mit filename an E-Mail-Nachricht anhängen"""
    with open(filename, 'rb') as fp:
        file_data = fp.read()
        maintype, _, subtype = (mimetypes.guess_type(filename)[0] or 'application/octet-stream').partition("/")
        email.add_attachment(file_data, maintype=maintype, subtype=subtype, filename=filename)

def send_mail_smtp(mail, host, username, password):
    s = smtplib.SMTP(host)
    s.starttls()
    s.login(username, password)
    s.send_message(mail)
    s.quit()

E-Mail so initialisieren:

create_email_msg.py
# Nachricht erstellen und Textinhalt setzen
msg = EmailMessage()
msg['Subject'] = 'This email contains an attachment'
msg['From'] = '[email protected]'
msg['To'] = '[email protected]'
# Textinhalt setzen
msg.set_content('Please see attached file')

und dann die Datei so anhängen:

attach_example.py
attach_file_to_email(msg, "myfile.pdf")

und die E-Mail senden mit

send_email_example.py
send_mail_smtp(msg, 'smtp.my-domain.com', '[email protected]', 'sae7ooka0S')
