我建议使用
MIMEApplication代替附件.您也不需要手动执行所有有效负载编码,因为这已经自动完成.这个例子对我有用：
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
from email.utils import formataddr
from email.utils import make_msgid
from email.utils import formatdate
email = MIMEMultipart()
email['From'] = formataddr(('Jane Doe', 'jane@'))
email['Subject'] = u'Test email'
email['Message-Id'] = make_msgid()
email['Date'] = formatdate(localtime=True)
email.attach(MIMEText(u'This is your email contents.'))
email.attach(MIMEApplication('your binary data'))
print email.as_string()
请注意,我还要注意在此处设置正确的Date和Message-Id标头.
将其应用于您的代码(并进行一些小的清理),我得到以下工作代码：
import smtplib
import os
from email.mime.multipart import MIMEMultipart
from email.mime.application import MIMEApplication
from email.mime.text import MIMEText
from email.utils import make_msgid
from email.utils import formatdate
def make_mail(address,body,format,mylist=[]):
msg = MIMEMultipart()
msg['To'] = address
msg['From'] = 'ggous1@'
msg['Message-Id'] = make_msgid()
msg['Date'] = formatdate(localtime=True)
msg.attach(MIMEText(body, 'plain' if format == 'txt' else 'html'))
for filename in mylist:
part = MIMEApplication(open(filename).read())
part.add_header('Content-Disposition',
'attachment; filename="%s"' % os.path.basename(filename))
msg.attach(part)
return msg
def send_mail(msg):
srv = smtplib.SMTP('')
srv.set_debuglevel(1)
srv.ehlo()
srv.starttls()
srv.ehlo()
srv.login('username','pass')
srv.sendmail(msg['From'], msg['To'], msg.as_string())
srv.quit()
if __name__=="__main__":
address=raw_input('Enter an address to send email in the form "name@" ')
body=raw_input('Enter the contents of the email')
format=raw_input('The format is txt or html?')
question=raw_input('Do you have any files to attach?Yes or No?')
mylist=[]
if question=='Yes' or question=='yes':
fn=raw_input('Enter filename')
mylist.append(fn)
msg = make_mail(address,body,format,mylist)
send_mail(msg)
