I am trying to write a python script to send an email that uses html formatting and involves a lot of non-breaking spaces. However, when I run it, some of the   strings are interrupted by spaces that occur every 171 characters, as can be seen by this example:
#!/usr/bin/env python
import smtplib
import socket
from email.mime.text import MIMEText
emails = ["[email protected]"]
sender = "test@{0}".format(socket.gethostname())
message = "<html><head></head><body>"
for i in range(20):
message += " " * 50
message += "<br/>"
message += "</body>"
message = MIMEText(message, "html")
message["Subject"] = "Test"
message["From"] = sender
message["To"] = ", ".join(emails)
mailer = smtplib.SMTP("localhost")
mailer.sendmail(sender, emails, message.as_string())
mailer.quit()
The example should produce a blank email that consists of only spaces, but it ends up looking something like this:
  ;
&nb sp;
& nbsp;
&nbs p;
&n bsp;
Edit: In case it is important, I am running Ubuntu 15.04 with Postfix for the smtp client, and using python2.6.

I can replicate this in a way but my line breaks come every 999 characters. RFC 821 says maximum length of a line is 1000 characters including the line break so that's probably why.
This post gives a different way to send a html email in python, and i believe the mime type "multipart/alternative" is the correct way. Sending HTML email using Python

I'm the developer of yagmail, a package that tries to make it easy to send emails.
You can use the following code:
import yagmail
yag = yagmail.SMTP('[email protected]', 'mypassword')
for i in range(20):
message += " " * 50
message += "<br/>"
yag.send(contents = message)
Note that by default it will send a HTML message, and that it also adds automatically the alternative part for non HTML browsers.
Also, note that omitting the subject will leave an empty subject, and without a to argument it will send it to self.
Furthermore, note that if you set yagmail up correctly, you can just login using yag.SMTP(), without having to have username & password in the script (while still being secure). Omitting the password will prompt a getpass.
Adding an attachment is as simple as pointing to a local file, e.g.:
yag.send(contents = [message, 'previously a lot of whitespace', '/local/path/file.zip']
Awesome isn't it? Thanks for the allowing me to show a nice use case for yagmail :)
If you have any feature requests, issues or ideas please let me know at github.
