使用实例

实例一：纯文本邮件

from Mail import Mail

mail = Mail('邮箱SMTP地址')
mail.login('发件人邮箱', '邮箱密码')
mail.title = "邮件标题"
mail.content = "邮件正文"
mail.receives = '收件人'
mail.send()
mail.logout()

实例二：给多人发邮件

from Mail import Mail

mail = Mail('邮箱SMTP地址')
mail.login('发件人邮箱', '邮箱密码')
mail.title = "邮件标题"
mail.content = "邮件正文"
mail.receives = ['收件人1', '收件人2']
mail.send()
mail.logout()

实例三：发带附件的邮件

from Mail import Mail

mail = Mail('邮箱SMTP地址')
mail.login('发件人邮箱', '邮箱密码')
mail.title = "邮件标题"
mail.content = "邮件正文"
mail.receives = ['收件人1', '收件人2']
mail.add_attachment('附件1路径')
mail.add_attachment('附件2路径')
mail.send()
mail.logout()

实例四：发图文邮件

from Mail import Mail

mail = Mail('邮箱SMTP地址')
mail.login('发件人邮箱', '邮箱密码')
mail.title = "邮件标题"
mail.content = "邮件正文"
mail.receives = ['收件人1', '收件人2']
mail.add_image('图片1路径')
# 后面还可以插入文本
mail.append_content('追加的文本内容')
# 还能插入图片
mail.add_image('图片2路径')
# 继续还能插入文本
mail.append_content('追加的文本内容2')
# 还可以带附件
mail.add_attachment('附件路径')
mail.send()
mail.logout()

邮件正文支持html的，如果需要格式，邮件内容写html代码即可。
