用python发邮件

用smtplib来发邮件

支持抄送、密送、加附件等功能。

测试程序

以发送ExASIC的订阅邮件为例，写了一个测试程序。

if __name__ == '__main__':

    # get mail list
    listfile = open('list.f', 'r')
    maillist = listfile.readlines()
    maillist.append('chenfengrugao@163.com')

    for mailto in maillist:
        print(mailto.rstrip('\n'))

        # setup mailer
        mailer = pymailer({'host': 'smtp.mxhichina.com',
                           'port': '465', #465 is for ssl, and 25 is for nossl
                           'email': 'chenfeng@exasic.com', #email account
                           'password': '******, #email password
                           'from': 'Chenfeng', # your name
                           'using_ssl': True}) #whether to use ssl

        mailer.add_to([mailto.rstrip('\n')])
        #mailer.add_bcc(['exasic <chenfeng@exasic.com>'])
        #mailer.add_attach('xxx.pdf')
        #mailer.add_attach('xxx.ppt')

        mailer.send_mail('ExASIC的订阅文章：IC验证导学',
                         """
