The section of Python code below is working for me to send a single attachment to an email when FileList = "/Users/jamescook/Documents/MailTest/MC70165.pdf".
with open(FileList, "rb") as attachment:
part = MIMEBase("application", "octet-stream")
part.set_payload(attachment.read())
encoders.encode_base64(part)
part.add_header(
"Content-Disposition",
f"attachment; filename= {FileList}",
)
msg.attach(part)
text = message.as_string()
But I need to sometimes have multiple attachments. Between indenting and where a loop would end, I've been unable to successfully loop through when FileList = '/Users/jamescook/Documents/MailTest/MC70165.pdf', '/Users/jamescook/Documents/MailTest/MT40125.pdf','/Users/jamescook/Documents/MailTest/ReadMe.txt'.
I need to embed multiple images into an email's body. I have tried below code but it does not embed it to the email's body. I am not looking to make it as an attachment
with open(i, 'rb') as f:
my_logo = FileAttachment(
name=i,
content=f.read(),
is_inline=True,
content_type='GIF/Image',
content_id=i,
)
m.attach(my_logo)
Thanks
Check out the example in the exchangelib documentation: https://ecederstrand.github.io/exchangelib/#attachments
In addition to creating the attachment, you need to reference it in your HTML body:
message = Message(...)
logo_filename = 'logo.png'
with open(logo_filename, 'rb') as f:
my_logo = FileAttachment(
name=logo_filename, content=f.read(),
is_inline=True, content_id=logo_filename,
)
message.attach(my_logo)
message.body = HTMLBody(
'<html><body>Hello logo: <img src="cid:%s"></body></html>' % logo_filename
)
How can the remote attachment file be specified to be included in SMTP mail? Attachement file is located on different server (own username/password access)
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
mail_content = """ This is body content """
sender_addr = "sender_addr#server.com"
sender_pass = "apassword"
receiver_addr = "receiver_addr#server.com"
# Create MIME header
msg = MIMEMultipart()
msg['From'] = sender_addr
msg['To'] = receiver_addr
msg['Subject'] = 'A test mail subject sent by Python'
msg.attach(MIMEText(mail_content, 'plain'))
fname = "doc_1.pdf"
attach_file = open(fname, 'rb') # **<- How can I specify the remote path here?**
payload = MIMEBase('application', 'octet-stream')
# Attach an attachment to payload
payload.set_payload((attach_file).read())
encoders.encode_base64(payload)
# Add payload header with filename
payload.add_header('Content-Disposition', 'attachment', filename=fname)
msg.attach(payload)
# Create SMTP client
client = smtplib.SMTP('smtp.gmail.com', 587)
client.starttls()
client.login(sender_addr, sender_pass)
text = msg.as_string()
client.sendmail(sender_addr, receiver_addr, text)
client.quit()
print('Mail sent!')
https://www.rfc-editor.org/rfc/rfc2110#section-4.1 explains the Content-Location: header.
Assuming the content you want to link to is in the variable attach_uri, something like
# Create MIME header
msg = MIMEMultipart()
msg['From'] = sender_addr
msg['To'] = receiver_addr
msg['Subject'] = 'A test mail subject sent by Python'
msg.attach(MIMEText(mail_content, 'plain'))
payload = MIMEBase('application', 'octet-stream')
payload.add_header('Content-Location', attach_uri)
msg.attach(payload)
If you are asking how to retrieve stuff from a remote location and include it in an email, that's a pretty broad topic; but assuming you have the content on an HTTP server, try something like
import requests
r = requests.get(attachment_uri)
payload.set_payload(r.content)
before you msg.attach(payload).
With this, there should be no need to set the Content-Location: to the original URI any longer (why would the user care where it came from? And you don't want to reveal the password etc).
I would like to check if the mail i get have an .msg attachment file, so when i try to parse my mailbox, it's recognized as an mail and not as an attachment file
I tried to get every type of attachment file, but it doesn't work
mBoxes = mail.list()
mail.select("INBOX")
result, data = mail.search(None, "ALL")
ids = data[0].split() # data is a list.
for email_id in ids:
fstab.write("\n")
result, data = mail.fetch(email_id, "(RFC822)") # fetch the email body (RFC822) for the given ID
email_body=data[0][1]
listattachments=[]
m = email.message_from_bytes(email_body)
for part in m.walk():
if bool(fileName):
filePath = os.path.join("/home/nguyen/Documents/SPAMS/", 'attachments', str(len(listfilename))+fileName )
if not os.path.isfile(filePath) and ".jpg" not in fileName and ".p7s" not in fileName and ".png" not in fileName and "#" not in fileName :
listfilename.append(fileName)
listattachments.append(fileName) #Check number of attachments per mail
fstab.write(filePath+"\n")
fp = open(filePath, 'wb')
fp.write(part.get_payload(decode=True))
fp.close()
I expect to get .msg file attachment too, but the script read the file attachment as a mail directly
I've created a sample function to test sending emails with an attached html file, which i intend to use for reporting on automated test runs in the future (replacing an existing external powershell script). Note that I'm attaching the html file, not using the html as inline text in the body. I'm using our company's mailgun smtp account service to send the email.
I seem to have an issue with Outlook 365 (web hosted - uses the outlook.office.com domain) either rejecting or blocking the sent email, but interestingly the same email is received and accepted by my personal hotmail address (outlook.live.com domain). I've found Outlook 365 blocks or does not accept the email when I attempt to name the file in the email message object. But if I don't name it, it will come through (with a default name of "ATT00001.htm" ).
My code for this is below but they key line seems to be
msg.add_attachment(open_file.read(), maintype='text', subtype='html', filename=filename)
If I drop the filename key it works (but with a default assigned filename) e.g.
msg.add_attachment(open_file.read(), maintype='text', subtype='html')
I have a suspicion there is something in the attachment's header or Content-disposition that Outlook 365 doesn't agree with, but i'm not sure what it is or how to work around.
I'm using the following (Python 3.6.5, on Windows 10 machine, smtplib and email.message seem to be built in)
Here is the code:
import smtplib
from email.message import EmailMessage
import os
def send_mail():
MAILGUN_SMTP_LOGIN = "<my company's mailgun login>"
MAILGUN_SMTP_PASSWORD = "<my company's mailgun password>"
fromaddr = "muppet#sharklasers.com" # the from address seems to be inconsequential
toaddr = ['me#mycompanysdomainusingoffice365.com.au', 'me#hotmail.com']
msg = EmailMessage()
msg.preamble = 'This is preamble. Not sure where it should show in the email'
msg['From'] = fromaddr
msg['To'] = ', '.join(toaddr)
msg['Subject'] = 'Testing attached html results send'
msg.set_content(""" This is a test of attached html """)
filename = 'api_automatedtests_20180903_1341.html'
filepath = os.path.abspath('D:/work/temp/api_automatedtests_20180903_1341.html')
open_file = open(filepath, "rb")
# msg.make_mixed()
msg.add_attachment(open_file.read(), maintype='text', subtype='html', filename=filename)
# msg.add_attachment(open_file.read(), maintype='text', subtype='html')
server = smtplib.SMTP(host="smtp.mailgun.org", port=587)
server.ehlo()
server.starttls()
server.login(MAILGUN_SMTP_LOGIN, MAILGUN_SMTP_PASSWORD)
server.set_debuglevel(1)
server.send_message(msg)
server.quit()
if __name__ == "__main__":
send_mail()
What I've tried
Tried sending with the same code using a textfile (with appropriate types). e.g.
msg.add_attachment(open_file.read(), maintype='text', subtype='plain', filename=filename)
Result: This works as expected (comes through with the given name - the filename is a string variable e.g. testfile.txt)
adding msg.make_mixed() to make sure it is identified as a multipart message. Result: No effect
Turning on the smtp debug level 1, Result: Mailgun says that everything has worked fine (and the messages do appear as expected in my hotmail account)
Not using the filename key in the msg.add_attachment call.
Result: This works the attachment comes through at ATT00001.htm
Interestingly the default name is *.htm while the filename I'm trying to use is *.html
Tried using a filename with *.htm and a subtype of 'htm' (instead of html)
Result: Same as for html (received on hotmail but not on outlook 365)
Tried using the generic types of maintype=''application', subtype='octet-stream'.
e.g. msg.add_attachment(open_file.read(), maintype='application', subtype='octet-stream', filename=filename)
Result: Same as for html (received on hotmail but not on outlook 365)
Tried using mimetypes.guess as shown in this link
https://docs.python.org/3.6/library/email.examples.html
ctype, encoding = mimetypes.guess_type(path)
if ctype is None or encoding is not None:
# No guess could be made, or the file is encoded (compressed), so
# use a generic bag-of-bits type.
ctype = 'application/octet-stream'
maintype, subtype = ctype.split('/', 1)
with open(path, 'rb') as fp:
msg.add_attachment(fp.read(),
maintype=maintype,
subtype=subtype,
filename=filename)
Result: It's determined as maintype='text', subtype='html' and I get the same result as with my original code (ie arrives in hotmail but blocked by 365).
Checking my spam and clutter folders - was not there
Any suggestions on why the use of filename would be breaking it?
Update
After sending to a other email addresses with various providers I discovered:
1) muppet#sharklasers.com was not a trusted sender (can change this)
2) I discovered the attachment was being flagged as unsafe. The html file comes from pytest's html report with the single file option. It contains javascript for row expanders. Gmail warns the attachment may not be safe (office 365 just straight out blocks the email altogether).
Not sure how to work around 2). I can email the same file to myself between outlook 365 and gmail and vice versa and the file doesn't get blocked. It only get's blocked when I use the above script using python's libraries and Mailgun SMTP. I suspect there is something I need to change in the email header to get around this. But I don't know what.
There seems to be some connection between trying to add the filename and the attachment being marked as unsafe
Okay I figured it out. The problem was the content-type needed to include "name=filename" in it's value.
Also I needed to use maintype='multipart', subtype='mixed'.
I have 2 solutions.
solution 1
import smtplib
from email.message import EmailMessage
import os
def send_mail(body_text, fromaddr, recipient_list, smtp_login, smtp_pass, file_path):
msg = EmailMessage()
msg.preamble = 'This is preamble. Not sure where it should show'
msg['From'] = fromaddr
msg['To'] = ', '.join(recipient_list)
msg['Subject'] = 'API Testing results'
msg.set_content(body_text)
filename = os.path.basename(file_path)
open_file = open(file_path, "rb")
msg.add_attachment(open_file.read(), maintype='multipart', subtype='mixed; name=%s' % filename, filename=filename)
server = smtplib.SMTP(host="smtp.mailgun.org", port=587)
server.ehlo()
server.starttls()
server.login(smtp_login, smtp_pass)
server.send_message(msg)
server.quit()
if __name__ == "__main__":
smtp_login = "<my smtp login>"
smtp_pass = "<my smtp password>"
recipient_list = ['user1#mycompany.com.au', 'user2#mycompany.com.au']
file_path = os.path.abspath('D:/work/temp/api_automatedtests_20180903_1341.html')
body_text = "test results for 03/09/2018 "
fromaddr = 'autotesting#mycompany.com.au'
send_mail(body_text=body_text, recipient_list=recipient_list, smtp_login=smtp_login, smtp_pass=smtp_pass,
file_path=file_path)
solution 2 (according to the documentation using the email.mime libraries is a legacy solution and the EmailMessage method is supposed to be used in preference.

msg.attach(MIMEText(body_text, 'plain'))
filename = os.path.basename(file_path)
attachment = open(file_path, "rb")
part = MIMEBase('multipart', 'mixed; name=%s' % filename)
part.set_payload(attachment.read())
