python实现电子邮件（E-mail）发送

       前几天需要服务端发送邮件的脚本，发现直接用sendmail相对来说复杂，大才小用了，因为我只需要一个发送的功能即可。于是查查改改，很容易弄了一个。

       python弄这些简单的email client,http client, tcp client之类的真的很方便，而且windows上也可以直接执行。

# Import smtplib for the actual sending function
import sys
import getopt
import smtplib

sender = 'sender@xxxx'
# If there are more than one receiver, you need to ganerate a list. 
# receiver = ['a@xxxx','b@xxxx']
receiver = ['receiver@xxxx']  
server = 'smtp.mail.xxxx.cn'
port = '25'
pwd = 'password'

COMMASPACE = ', '

# Import the email modules we'll need
from email.mime.text import MIMEText

def usage():
    usageStr = '''Usage: SendEmail -c mail_content'''
    print usageStr

def main(argv):
    # Get the Email content in the "-c" argv
    try:
        opts, args = getopt.getopt(argv, "c:")
    except getopt.GetoptError:
        usage()
        sys.exit(2)

    content = ''

    for opt, arg in opts:
        if opt == '-c':
            content = arg

    print content

    msg = MIMEText(content)
    
    msg['Subject'] = 'this is the subject'
    msg['From'] = sender
    msg['To'] = COMMASPACE.join(receiver)
    
    s = smtplib.SMTP(server, port)
    s.ehlo()
    s.login(sender, pwd)
    s.sendmail(sender, receiver, msg.as_string())
    s.quit()

if __name__=="__main__":
    main(sys.argv[1:])

python版本比较老时会遇到这种报错：

ImportError: No module named mime.text

解决办法：

将这句from email.mime.text import MIMEText

改为：

from email.MIMEText import MIMEText
from email.Header import Header
