解决python发送邮件乱码

一.邮件主题乱码

1.打开python的Lib文件夹下的 mimetypes.py 文件，找到大概256行的

‘default_encoding = sys.getdefaultencoding()’。

在这行前面添加三行，并且注释4行代码

#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.在代码中加入下面片段

reload(sys) 
sys.setdefaultencoding(gb18030)

在代码中对内容做如下处理

msg = MIMEText(content,format,gbk)

#!/usr/bin/python
#coding:utf-8 
 
import smtplib
from email.mime.text import MIMEText
import sys 
 
#邮箱服务器地址
mail_host = smtp.163.com
#邮箱用户名
mail_user = XXX
#邮箱密码
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])
