Given that yout code is arranged to print an error message it's a pity you
didn't give us the benefit of its output so we knew a little more about the
erre that's occurring.

The arguments to the .sendmail() method should be:

    a string containing the sender's address
    a list of strings containing an address for each recipient, and
    an RFC822-formatted mail message

I am guessing that when you say "but when I add another, using a comma to
separate the addresses, the second address fails to receive the mail" you
are setting the self.mailTo attribute to be a comma-separated list ot
recipients? Frankly I'm not sure how you are managing to get this mail
formatted.

What you really want for multiple recipients is something like the
following:


    self.mailFrom = me at mydomain.com
    self.mailTo = ["him at hisdomain.com", "her at herdomain.com",
"it at itsdomain.net"]
    ...
    mailMessage = "From: %s \r\nTo: %s\r\n" \
                % (self.mailFrom, ", ".join(self.mailTo))
    mailMessage += "Subject: %s\r\n%s" % (mailSubject, mailBody)
        try:
            self.MailConn.sendmail( self.mailFrom, self.mailTo, mailMessage)
        except (smtplib.SMTPRecipientsRefused,
                smtplib.SMTPSenderRefused), ErrorMsg:
            print "There Was A Problem Sending The Mail.  Reason: %s" \
                    % ErrorMsg

In other words, use a comma-separated list of recipients in the message
body, but a list of email addresses as the second argument to .sendmail().
