SMTP Sending Mail Problem

Hi all,
I'm fairly new to python, but very excited about it's potential.

I'm trying to write a simple program that will accept input from a
command line and send email. The parameters I used on the command
line are for From address, To addresses, Subject and Body. For the
body, I thought it would be better to read the input from a file so I
could allow someone to nicely format the body with newlines in a text
editor and just read it into a string and send it.

However, whenever I try to read more than one line from the file, the
email is not being delivered. The only reason I know this is because
I tried just reading in the first line of the text file, and the email
sent fine. Right now I believe this must have something to do with
new line characters at the end of each line, but it doesn't quite make
sense to me why this is a problem, as I have also used the same script
and just created a string in it with multiple lines (\r\n) and sent it
and the email sends fine. To complicate the issue further, I have
turned used the set_debuglevel method so I can see the output from the
SMTP server, and it appears that the message was Queued for mail
delivery.

The SMTP server we are using is Exchange if that matters. I have
listed the code below, along with output from the SMTP server. Any
help would be much appreciated. (Note, I don't typically read in the
file with a range(n) iterator, but that is how I have noticed that I
can send only one line, but not send multiple lines. As soon as I
change the range value to 1, the email will successfully send the
first line of the text file).

import sys,smtplib
if len(sys.argv) != 5:
print """
Usage: sendmail FROM RECIPIENTS SUBJECT BODY
RECIPIENTS should be a semicolon delimited list of email addresses.
BODY should be a file where the message to send is stored
Use double quotes to surround the SUBJECT element if it is more than
one word
"""
exit()
fromaddr = sys.argv[1]
toaddrs = sys.argv[2].split(";")
subject = sys.argv[3]
body = ""
print toaddrs
print type(toaddrs)
try:
infile = open(sys.argv[4], 'r')
for i in range(4):
body = body + infile.readline()
except IOError:
print "Can't open the given file, please try again"
exit()
headers = "From: %s\r\nTo: %s\r\nSubject: %s\r\n\r\n" % (fromaddr, ",
".join(toaddrs), subject)
msg = headers + body
server = smtplib.SMTP('##############')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()

Output:
