    Unhappy SMTP duplicated...


    i had wrote some code to send mail with attachment by using MIMEMultipart.

    the .py is looks like this...
    i have written a .py file (test_mail.py) to provide several input that needs to send a mail with some attachments. it calls the implementation file.
    besides, i also have a file called send_mail.py which serves as the implemetation for formatting & send out the mail. all MIMEMultipart object is defined inside this .py file.

    the error i have is the mail will be duplicated sent when i execute test_mail.py for the 2nd, 3rd... time
    eg: if i execute test_mail.py for 3 times, i will received 3 mails. if the file size of the 1st mail is 50kb, the 2nd mail's file size is 100kb, and the 3rd mail file size will be 150kb. all message and attachment files will be duplicated as long as i call the test_mail.py again.

    i need some help from you guys..
    thanks for advice,

    here is the code for the test drive file...

        # general info

        RECEIVER = str(d_actionMail.get('Receiver'))
        SUBJECT = str(d_actionMail.get('Subject'))
        # msg info
        fp_info = open('att_mail.txt', 'r')
        m_info = fp_info.read()
        # attachment files
        l_att = []
        # call implementation file
