在linux中如何实现定时发送邮件到指定邮箱，监测任务

1 #!/usr/bin/env python
 2 # -*- coding=utf-8 -*-
 3 import smtplib
 4 from email.mime.text import MIMEText
 5 import threading
 6 import time, datetime
 7 
 8 mailto_list=["lovychen@126.com"] #里面是对方的邮箱
 9 #-----------QQ邮箱发送设置----------------------
10 mail_server="smtp.qq.com"#以qq邮箱为例子，里面是QQ邮箱的服务，换成其他邮箱需要更改服务
11 mail_user=""#这是QQ邮箱的账号
12 mail_pass=""#如果是其他的可以直接填上密码，如果用qq之类的，或者邮箱未开服务，会提醒你打开下面的链接
13 #QQ邮箱需要去官方打开服务：http://service.mail.qq.com/cgi-bin/help?subtype=1&&id=28&&no=1001256
14 def send_mail(to_list, sub, content):
15     msg = MIMEText(content,'plain','utf-8')
16     msg["Accept-Language"]="zh-CN"
17     msg["Accept-Charset"]="ISO-8859-1,utf-8"
18     msg['Subject'] = sub
19     msg['From'] = mail_user
20     msg['To'] = ";".join(to_list)
21     try:
22         server = smtplib.SMTP()
23         server.connect(mail_server)
24         server.starttls()
25         server.login(mail_user, mail_pass)
26         server.sendmail(mail_user, to_list, msg.as_string())
27         server.close()
28         return True
29     except Exception, e:
30         print str(e)
31         return False
32 
33 def getDate():
34     return str(datetime.datetime.utcfromtimestamp(time.time())+datetime.timedelta(hours=8))
35 
36 def send_warning_mail(title, info):
37     nowTime = getDate()
38     try:
39         t = threading.Thread(target=send_mail, args=(mailto_list, title, str(nowTime) + " | " + str(info)))
40         t.start()
41     except:pass
42     # send_mail(mailto_list, "mysql异常", info)
43 
44 if __name__ == '__main__':
45     send_warning_mail("this is title", "
this is content")
46 #     print 111

这是能够加上附件的邮件发送：
 1 #!/usr/bin/env python 
 2 #coding=utf-8  
3 import smtplib  
4 from email.MIMEText import MIMEText  
5 from email.MIMEMultipart import MIMEMultipart  
6 from email.MIMEBase import MIMEBase  
7 from email import Encoders  
8 import time  
9 mail_body='hello, this is the mail content' 
10 mail_from=''#发件人的邮箱 
11 mail_to=['']#收件人邮箱 
12 # 构造MIMEMultipart对象做为根容器 
13 msg=MIMEMultipart() 
14 
15 # 构造MIMEText对象做为邮件显示内容并附加到根容器
 16 body=MIMEText(mail_body)
 17 msg.attach(body) 
18 
19 # 构造MIMEBase对象做为文件附件内容并附加到根容器
 20 # 等同于如下3行 
21 #contype = 'application/octet-stream' 
22 #maintype, subtype = contype.split('/', 1) 
23 #part = MIMEBase(maintype, subtype) 
24 part = MIMEBase('application', 'octet-stream') 
25
 26 # 读入文件内容并格式化，此处文件为当前目录下，也可指定目录 例如：open(r'/tmp/123.txt','rb') 
27 part.set_payload(open('123.txt','rb').read())
 28 Encoders.encode_base64(part) 
29 ## 设置附件头 
30 part.add_header('Content-Disposition', 'attachment; filename="herb.zip"') 
31 msg.attach(part) 
32 
33 # 设置根容器属性 
34 msg['Subject']='this is the title' 
35 msg['From']=mail_from
 36 msg['To']=';'.join(mail_to) 
37 msg['date']=time.strftime('%a, %d %b %Y %H:%M:%S %z') 
38 #如上得到了格式化后的完整文本msg.as_string() 
39 #用smtp发送邮件 
40 smtp=smtplib.SMTP() 
41 smtp.connect('')#服务，如果是163的邮箱，就填上smtp.163.com 
42 smtp.login('发件的邮箱','发件的密码')
 43 smtp.sendmail(mail_from,mail_to,msg.as_string()) 
44 smtp.quit() 
45 print 'ok'
