python发送邮件示例(支持中文邮件标题)

复制代码 代码如下:

def sendmail(login={},mail={}):
'''\
@param login login['user'] login['passwd']
@param mail mail['to_addr'] mail['subject'] mail['content'] mail['attach']
'''
from datetime import datetime

mail_configure['server_host'] = 'smtp.%s' % mail_configure['mail_supplier']

    email_content = MIMEText(mail['content'], _charset=mail_configure['mail_encoding'])  
    email.attach(email_content)

    if 'attach' in mail:

            if ctype is None or not encoding is None:

            maintype, subtype = ctype.split('/', 1)  
            att = MIMEImage((lambda f: (f.read(), f.close()))(open(i, 'rb'))[0], _subtype = subtype)  
            att.add_header('Content-Disposition', 'attachment', filename = i)  
            email.attach(att)

    smtp = smtplib.SMTP()  
    smtp.connect(mail_configure['server_host'])  
    smtp.login(user_info[0], login['passwd'])  
    smtp.sendmail(mail_configure['from_addr'], mail['to_addr'], email.as_string())
