New submission from Michal Sladek <mic...@sladkovi.eu>:
Hello!
I think there is a problem when adding UTF-8 subject to email message. I wrote
following function (its code is based on examples I found in offical docs)
which should send an email with UTF-8 subject, UTF-8 plain text body and
attached file when all arguments are given.
fromAddr - address of sender
toAddr - address of recipient
subject - subject
body - text of email body
attachment - full path to file we want to attach
Here is the code:
def sendMail (fromAddr, toAddr, subject, body = '', attachment = ''):
message = email.mime.multipart.MIMEMultipart()
message.add_header('From',fromAddr)
message.add_header('To',toAddr)
message['Subject'] = email.header.Header(subject,'utf-8')
if (body != ''):
msgPart = email.mime.text.MIMEText(body,'plain','utf-8')
message.attach(msgPart)
if (attachment != ''):
if os.path.exists(attachment) == True:
filename = attachment.rpartition(os.sep)[2]
fp = open(attachment,'rb')
msgPart = email.mime.base.MIMEBase('application','octet-stream')
msgPart.set_payload(fp.read())
fp.close()
email.encoders.encode_base64(msgPart)
msgPart.add_header('Content-Disposition','attachment',filename=filename)
message.attach(msgPart)
if smtpPort == 25:
smtpCon = smtplib.SMTP(smtpSrv,smtpPort)
else:
smtpCon = smtplib.SMTP_SSL(smtpSrv,smtpPort)
if (smtpUser != '') and (smtpPass != ''):
smtpCon.login(smtpUser,smtpPass)
smtpCon.send_message(message,mail_options=['UTF8SMTP','8BITMIME'])
smtpCon.quit()
Running the function with following arguments:
sendMail('rzro...@seznam.cz','msla...@volny.cz','žluťoučký kůň','úpěl ďábelské
ódy')
produces following output on receiving side:
Return-Path: <rzro...@seznam.cz>

Although no attachment argument was given, the client says that message has an
attachment of unknown type and that message does not contain any text at all.
See that message part header :Content-Type: text/plain; charset="utf-8" is part
of the message part boundary instead of beeing inside of the message part.
When I change the code of function to generate the subject manually and add it
via add_header like this:
def sendMail (fromAddr, toAddr, subject, body = '', attachment = ''):
message = email.mime.multipart.MIMEMultipart()
message.add_header('From',fromAddr)
message.add_header('To',toAddr)
base64Subject = base64.b64encode(subject.encode('utf-8')).decode()
encodedSubject = '=?UTF-8?B?{0}?='.format(base64Subject)
message.add_header('Subject',encodedSubject)
if (body != ''):
msgPart = email.mime.text.MIMEText(body,'plain','utf-8')
message.attach(msgPart)
if (attachment != ''):
if os.path.exists(attachment) == True:
filename = attachment.rpartition(os.sep)[2]
fp = open(attachment,'rb')
msgPart = email.mime.base.MIMEBase('application','octet-stream')
msgPart.set_payload(fp.read())
fp.close()
email.encoders.encode_base64(msgPart)
msgPart.add_header('Content-Disposition','attachment',filename=filename)
message.attach(msgPart)
if smtpPort == 25:
smtpCon = smtplib.SMTP(smtpSrv,smtpPort)
else:
smtpCon = smtplib.SMTP_SSL(smtpSrv,smtpPort)
if (smtpUser != '') and (smtpPass != ''):
smtpCon.login(smtpUser,smtpPass)
smtpCon.send_message(message,mail_options=['UTF8SMTP','8BITMIME'])
smtpCon.quit()
Then everything is OK on receiving side, both subject and plaint text body are
visible:

I am not a programmer so I might overlook some obvious mistake in my code but
for now I think it's a bug.
