import codecs, collections
import tempfile
import zipfileJPN as zipfile
import unittest, time, re, os, sys,datetime, shutil
import MimeWriter, mimetools, base64, StringIO

    smtp.sendmail(from_addr, to_addrs+cc_addrs, msg.as_string())
    smtp.close()

if __name__ == '__main__':
    from_addr="[email protected]"
    from_addr_name = "test"
    to_addr = "[email protected],[email protected]"

    send(from_addr,to_addr_list, cc_addr_list, msg)

4. Description

1. Send an email using python

--I sent an email using smtplib of python. --smtp = smtplib.SMTP ("localhost: host") with smtp server name and host --You can send an email by writing smtp.sendmail (sending email address, destination email address, contents of the email) and sending it.

def send(from_addr, to_addrs, cc_addrs, msg):
    smtp = smtplib.SMTP("localhost:host")#Change required
    smtp.sendmail(from_addr, to_addrs+cc_addrs, msg.as_string())
    smtp.close()

2. Set multiple people for destination and Cc

--Write in to_addrs + cc_addrs of smtp.sendmail (from_addr, to_addrs + cc_addrs, msg.as_string ()) as a string like "[email protected],[email protected], [email protected]" ( A string of destination names separated by commas) --Please note that if you enter the wrong address, it may be sent only to the beginning.

3. Attach the zip file

--Write the files in the target folder in zip format --Set MIME type and set as attachment --I created a zip file in advance, set the MIME type to zip and sent it, but I was able to send it, but the file may be corrupted.

  zf = tempfile.TemporaryFile(prefix='mail', suffix='.zip')
    zip = zipfile.ZipFile(zf, 'w')
    files = os.listdir(attach_file['path'])
    for i in files:
        filename =""
        filename=i
        zip.write(attach_file['path']+"/"+(filename.decode("cp932")).encode("cp932"))
    zip.close()
    zf.seek(0)

4. Use Japanese for attachment names

--Since the zipfile.write (file path) function of python2.7 is converted to UTF-8, if you use the Japanese file name as it is, you cannot specify the file. --Correspond by modifying the library, creating it as a new library, and importing it. --Copy zipfile.py in C: \ Python27 \ Lib, create it as a file with a new name, change utf-8 to cp932 (Japanese character code of Windows) and save it.
