sending emails to a list of recipients

[Kun]

i have the following code:

----------------------------------
import smtplib

from email.MIMEText import MIMEText
fp = open('confirmation.txt', 'rb')
msg = MIMEText(fp.read())

From = 'x***@xxxx.xxxx.edu'

msg['Subject'] = 'Purchase Confirmation'
msg ['From'] = From
msg['To'] = emails

s = smtplib.SMTP('xxxx.xxx.xxx.edu')
s.login('xxxxx','xxxx')
s.sendmail(msg['From'], msg['To'], msg.as_string())
s.close()
----------------------------------

it works if msg['To'] = 'e****@email.com'

however, i'm trying to attach a list of emails named 'emails' to msg['To']

emails is in the following format: ['n***@gmail.com', 'n***@gmail.com',
'x**@xxx.xxxx.edu']
anyone have an idea how i can modify this script to work with sending a
list? note this is a snippet of a larger code, 'emails' is as a string
defined earlier.

smtplib docs http://python.active-venture.com/lib/SMTP-example.html
say that the to should be a list of addresses (your emails);

s.sendmail(msg['From'], emails, msg.as_string())

What did you try? You should just be able to pass the list:

s.sendmail( msg['From'], emails, msg.as_string() )
Or, if you must,
msg['To'] = emails
s.sendmail( msg['From'], msg['To'], msg.as_string() )

It needs to be a list or tuple of individual addresses, e-mail only, with
no "nicknames". If you tried that, what did you see?
maybe try : msg['To'] = ', '.join( emails )

No, you misread the example. It uses that in the headers of the message.
That won't work for the second parameter of SMTP.sendmail.

OK, I see what's going on now. The problem is that SMTP.sendmail and
email.MIMEText need two different things.

email.MIMEText sets up the "To:" header for the body of the e-mail. It is
ONLY used for displaying a result to the human being at the other end, and
like all e-mail headers, must be a single string. (Note that it does not
actually have to have anything to do with the people who actually receive
the message.)

SMTP.sendmail, on the other hand, sets up the "envelope" of the message for
the SMTP protocol. It needs a Python list of strings, each of which has a
single address.

So, what you need to do is COMBINE the two replies you received. Set
msg['To'] to a single string, but pass the raw list to sendmail:

msg['To'] = ', '.join( emails )
....
s.sendmail( msg['From'], emails, msg.as_string() )
