python3發送郵件（有附件）
代碼一：

from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.image import MIMEImage
from email.utils import formatdate
import os
#設置登錄及服務器信息

mail_user = 'h***@vcredit.com'
mail_pass = 'h****'
sender = 'h***@vcredit.com'
receivers = ['p****@vcredit.com']
#設置eamil信息
#添加一個MIMEmultipart類，處理正文及附件
message = MIMEMultipart()
message['From'] = sender
message['To'] = receivers[0]
message['Subject'] = '測試'
message['Date'] = formatdate( )
#推薦使用html格式的正文內容，這樣比較靈活，可以附加圖片地址，調整格式等
with open('abc.html','r') as f:
content = f.read()
#設置html格式參數
part1 = MIMEText(content,'html','utf-8')
basename = os.path.basename("report.txt")
#添加一個txt文本附件
with open('report.txt','r')as h:
content2 = h.read()
#設置txt參數
part2 = MIMEText(content2,'plain','utf-8')
#附件設置內容類型，方便起見，設置為二進制流
part2['Content-Type'] = 'application/octet-stream'
#設置附件頭，添加文件名
part2['Content-Disposition'] = 'attachment;filename=%s' % basename
#解決中文附件名亂碼問題
# part2.add_header('Content-Disposition', 'attachment', filename=('utf-8', '', basename))
#添加照片附件
with open('1.png','rb')as fp:
picture = MIMEImage(fp.read())
#與txt文件設置相似
picture['Content-Type'] = 'application/octet-stream'
picture['Content-Disposition'] = 'attachment;filename="1.png"'
#將內容附加到郵件主體中
message.attach(part1)
message.attach(part2)
message.attach(picture)
#登錄並發送
try:

# smtpObj.connect(mail_host,25)
#需要SSL認證
smtpObj = smtplib.SMTP_SSL(mail_host)
smtpObj.login(mail_user,mail_pass)
smtpObj.sendmail(sender,receivers,message.as_string())
print('success')
smtpObj.quit()

經驗證使用代碼一從公司的Outlook郵箱發送到Outlook郵箱是沒有問題的，但是當附件的名稱為中文的時候，收到的郵件的附件名稱為
研究了很長時間，不知道怎么解決。。。
用代碼一從公司的Outlook郵箱發送到QQ郵箱，QQ郵箱收不到郵件（原因未知），不過可以使用代碼二發送到QQ郵箱，並且不存在未命名附件和亂碼的問題；但是發送到公司的Outlook郵箱不管是否為中文名稱的附件都存在未命名附件的問題。
解決方法：針對代碼二可以使用Foxmail收取Outlook的郵件，這樣不會出現未命名附件和亂碼的問題
代碼二：

MIME郵件的基本信息、格式信息、編碼方式等重要內容都記錄在郵件內的各種域中，域的基本格式：{域名}：{內容}，域由域名后面跟“：”再加上域的信息內容構成，一條域在郵件中占一行或者多行，
域的首行左側不能有空白字符，比如空格或者制表符，占用多行的域其后續行則必須以空白字符開頭。域的信息內容中還可以包含屬性，屬性之間以“;”分隔，屬性的格式如下：{屬性名稱}=”{屬性值}”。
