from email.MIMEText import MIMEText
from smtplib import SMTPException


def send_Email():
    file1="abc.txt"
    message = "Test mail"
    msg = MIMEMultipart()

    msg.attach(MIMEText(file(file1).read()))

    try:
        smtpObj = smtplib.SMTP('smtp server name',port)
        smtpObj.sendmail(sender, EmailId, message, msg.as_string() )
        print "Successfully sent email"
    except SMTPException:
        print "Error: unable to send email"
