学习pyton mail 模块 记录了一个实例程序，支持gmail 和163区分账户发送；支持发送多人，抄送，正文汉字不乱码，发送人汉字姓名；还支持发送附件；

说一下编写这个程序遇到的问题：

1、163 邮件不能发送

目前发送163 的邮件需要ssl加密方式登录：

因此登录时要用下面的方式登录；

    smtp = smtplib.SMTP_SSL(server) #163 mail  

而登录gmail要用下面这种方式

    smtp = smtplib.SMTP(server)  

    smtp.starttls() #gmail mail  

2、正文汉字乱码

正文乱码，需要添加下面的信息，默认的正文编码是us-acsii 格式，我们在linux下需要设置为utf-8

  msg["Accept-Language"]="zh-CN"  
  msg["Accept-Charset"]="ISO-8859-1,utf-8"  
     
  if isinstance(text,unicode):  
    text = str(text)  
  msg.attach( MIMEText(text,'plain','utf-8'))
 

整个实例代码:

#!/usr/bin/env python
#-*- encoding: UTF-8 -*-
#gmail_report.py

def send_mail(send_people, send_from, send_to, cc_to,
subject, text, files=[],
server="localhost", user = None, password = None):

assert type(send_to)==list
assert type(files)==list

msg = MIMEMultipart()

if send_people :
me= ("%s<"+send_from+">") % (Header(send_people,'utf-8'),)
msg['From'] = me
else :
msg['From'] = send_from
#print "from pepole",send_people

msg['To'] = COMMASPACE.join(send_to)
msg['Cc'] = COMMASPACE.join(cc_to)
send_to = send_to + cc_to # add cc_to to send_to

if not isinstance(subject,unicode):
subject = unicode(subject)
msg['Subject'] = subject

msg['Date'] = formatdate(localtime=True)
msg["Accept-Language"]="zh-CN"
msg["Accept-Charset"]="ISO-8859-1,utf-8"

if isinstance(text,unicode):
text = str(text)
msg.attach( MIMEText(text,'plain','utf-8'))

#add attach file
for file in files:
part = MIMEBase('application', "octet-stream")
part.set_payload( open(file,"rb").read() )
Encoders.encode_base64(part)
part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file))
msg.attach(part)

print "connect to %s" % server
# check server
pattern = re.compile(r'smtp.163.com')
match = pattern.match(server)

if match:
smtp = smtplib.SMTP_SSL(server) #163 mail
else :

smtp.starttls() #gmail mail

#print server

if (user != None):
smtp.ehlo()
smtp_userid64 = base64.encodestring(user)
smtp.docmd("auth", "login " + smtp_userid64[:-1])
if password != None:
smtp_pass64 = base64.encodestring(password)
smtp.docmd(smtp_pass64[:-1])

print "send mail form %s \n to %s" % (send_from,send_to)
smtp.sendmail(send_from, send_to, msg.as_string())
