1、準備

先做一些準備，把郵件SMTP服務(wù)器、收發(fā)mail、郵件標題和正文準備好。

mailhost = 'smtp.server.com'
mailport = 465
mailuser = 'mymail@server.com'
mailpass = '123456'

mailfrom = 'mymail@server.com'
mailto = []
mailto.append('customer@server.com')
mailsubject = '這是測試郵件標題'
mailbody = '
這里是郵件正文
'

2、發(fā)送郵件

連接SMTP服務(wù)器，一般服務(wù)器要求用SSL，所以SMTP_SSL()來連接。再用login(user, password)來驗證用戶名和密碼。登錄成功后，就可以sendmail()來發(fā)郵件了。下面是示例代碼：

import smtplib
from email.mime.text import MIMEText

msg = MIMEText(mailbody, 'html')
msg['From'] = mailfrom
msg['Subject'] = mailsubject
msg['To'] = ','.join(mailto)

try:
    mailserver = smtplib.SMTP_SSL(host=mailhost, port=mailport)
    #mailserver.set_debuglevel(1)
    mailserver.ehlo()
    mailserver.login(mailuser, mailpass)

    mailserver.sendmail(mailfrom, mailto, msg.as_string())
    mailserver.quit()
except Exception as e:
    print(e)
