用俄文文件nam发送电子邮件至exchange

Question

我使用的是python2.7.3。我有以下代码发送电子邮件与附件。在

# coding: cp1251
import os
import smtplib

from email import Encoders
from email.MIMEBase import MIMEBase
from email.MIMEMultipart import MIMEMultipart
from email.Utils import formatdate

def sendEmail(to_address, mail_settings, attachment_file_path, subject = 'my_subject'):

HOST = mail_settings['host']
port = mail_settings['port']
username = mail_settings['login']
password = mail_settings['pass']

msg = MIMEMultipart()
msg["From"] = mail_settings['from_address']
msg["To"] = ','.join(to_address)
msg["Subject"] = subject.decode('cp1251')
msg['Date'] = formatdate(localtime=True)
msg['Content-Type'] = "text/html; charset=cp1251"

# attach a file
part = MIMEBase('application', "octet-stream")
part.set_payload( open(attachment_file_path,"rb").read() )
Encoders.encode_base64(part)    
part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(attachment_file_path))
msg.attach(part)

server = smtplib.SMTP(host=HOST, port=port)           

try:
    failed = server.sendmail(mail_settings['from_address'], to_address, msg.as_string())        
    print('sent')
    server.close()
except Exception, e:
    errorMsg = "Unable to send email. Error: %s" % str(e)
    print(errorMsg)

我的问题是，通过这个代码接收电子邮件的exchange用户看不到附件文件名，如果它有俄文字母（例如Пример.txt），否则如果它有英文字母，那么对他们来说一切正常。 我只在使用exchange（gmail很好）的客户面前遇到这个问题。 我做错什么了？我应该在哪里更改编码？在

我终于找到了解决办法。我只是设置了标题的编码。在

mail_coding = 'utf-8'
att_header = Header(os.path.basename(attachment_file_path), mail_coding);
part.add_header('Content-Disposition', 'attachment; filename="%s"' % att_header)
