一.郵件主題亂碼

1.開啟python的Lib資料夾下的 mimetypes.py 檔案，找到大概256行的

‘default_encoding = sys.getdefaultencoding()’。

在這行前面新增三行，並且註釋4行程式碼

                #try:
                #    ctype = ctype.encode(default_encoding) # omit in 3.x!
                #except UnicodeEncodeError:
                #    pass
                else:
                    yield ctype
                i += 1

                if sys.getdefaultencoding() != 'gbk':  
                    reload(sys)  
                    sys.setdefaultencoding('gbk')
                default_encoding = sys.getdefaultencoding()
 

2.在程式碼中加入下面片段

reload(sys) 
sys.setdefaultencoding('gb18030')

在程式碼中對內容做如下處理

msg = MIMEText(content,format,'gbk')

#!/usr/bin/python
#coding:utf-8 
 
import smtplib
from email.mime.text import MIMEText
import sys 
 
#郵箱伺服器地址
mail_host = 'smtp.163.com'
#郵箱使用者名稱
mail_user = 'XXX'
#郵箱密碼
mail_pass = 'XXX'
mail_postfix = '163.com'
 
def send_mail(to_list,subject,content):
    format='plain'
    me = mail_user+"<"+mail_user+"@"+mail_postfix+">"
    msg = MIMEText(content,format,'gbk')
    reload(sys) 
    sys.setdefaultencoding('gb18030')
    if not isinstance(subject,unicode):
        subject = unicode(subject)
    msg['Subject'] = subject
    msg['From'] = me
    msg['to'] = to_list 
    msg['Accept-Language']='zh-CN'
    msg['Accept-Charset']='ISO-8859-1,utf-8'
 
    try:
        s = smtplib.SMTP()
        s.connect(mail_host)
        s.login(mail_user,mail_pass)
        s.sendmail(me,to_list,msg.as_string())
        s.close()
        return True
    except Exception,e:
        print str(e)
        return False
 
if __name__ == "__main__":
    send_mail(sys.argv[1], sys.argv[2], sys.argv[3])
