So the first mail has one recipient in the 'to' field, the second mail has the first and the second recipient, and so forth. I only want one recipient to be shown in the 'to' field. It's ugly and since I have a lot of email addresses to parse (4 years worth of emails!), it would become a very long list.

Hi Albert,
I got this to work;

#!/usr/bin/python

import smtplib, email.utils
from email.mime.text import MIMEText
from email.MIMEMultipart import MIMEMultipart
from email.Utils import COMMASPACE, formatdate

def recipients():
     recipients = ['happyhappy at joy.com', 'you at eediot.com]
     for no, recipient in enumerate(recipients):
         print "--> Sending message to: %s (%s of %s)" % (recipient, 
no+1, len(recipients))
         message(recipient)

def message(recipient):
     body = "Dear reader:\n\nblaaaaah blaah blaah.\nSincerely,\nThe dude"
     send_mail([recipient], 'Change of email address', body)


def send_mail(send_to, subject, text, server="mail.stimpy.com"):
     send_from = "ren at stimpy.com"
     msg = MIMEMultipart()
     msg['To'] = COMMASPACE.join(send_to)
     msg['Date'] = formatdate(localtime=True)
     msg['From'] = send_from
     msg['Subject'] = subject
     msg.attach( MIMEText(text) )
     smtp = smtplib.SMTP(server)
     smtp.sendmail(send_from, send_to, msg.as_string())
     smtp.close()

recipients()
