调用send_mail时卡在s.sendmail(me, to_list, fullText)不动了，很久才响应。

代码如下：

def send_mail(to_list,sub,content,path):

me=mail_user

main_msg = email.MIMEMultipart.MIMEMultipart()

text_msg = email.MIMEText.MIMEText(content,'html','utf-8')

main_msg.attach(text_msg)

contype = 'application/octet-stream'

maintype, subtype = contype.split('/', 1)

if path != "none":

data = open(path, 'rb')

file_msg = email.MIMEBase.MIMEBase(maintype, subtype)

file_msg.set_payload(data.read( ))

data.close( )

email.Encoders.encode_base64(file_msg)

## 设置附件头

basename = os.path.basename(path)

file_msg.add_header('Content-Disposition', 'attachment', filename = basename)

main_msg.attach(file_msg)

main_msg['From'] = me

main_msg['To'] = ";".join(to_list)

main_msg['Subject'] = sub

main_msg['Date'] = email.Utils.formatdate( )

fullText = main_msg.as_string( )

try:

s = smtplib.SMTP()

s.connect(mail_host)

s.login(mail_user,mail_pass)

s.sendmail(me, to_list, fullText)

s.close()

except Exception, e:

print str(e)
