New submission from Jay Patel <[email protected]>:
According to the user requirements, I need to send an email, which is provided
as a raw email, i.e., the contents of email are provided in form of headers. To
accomplish this I am using the methods provided in the "send_rawemail_demo.py"
file (attached below).
The smtplib library works fine when providing only 'ascii' characters in the
'raw_email' variable. But, when I provide any Unicode characters either in the
Subject or Body of the email, then the sendmail method of the smtplib library
fails with the following message:
UnicodeEncodeError 'ascii' codec can't encode characters in position 123-124:
ordinal not in range(128)
I tried providing the mail_options=["SMTPUTF-8"] in the sendmail method (On
line no. 72 in the send_rawemail_demo.py file), but then it fails (even for the
'ascii' characters) with the exception as SMTPSenderRefused.
I have faced the same issue on Python 3.6.
The sendmail method of the SMTP class encodes the message using 'ascii' as:
if isinstance(msg, str):
msg = _fix_eols(msg).encode('ascii')
The code works properly for Python 2 as the smtplib library for Python 2 does
not have the above line and hence it allows Unicode characters in the Body and
the Subject.
