创建一个mbox邮箱

# mailbox_mbox_create.py
import mailbox
import email.utils

from_addr = email.utils.formataddr(('Author',
                                    'author@example.com'))
to_addr = email.utils.formataddr(('Recipient',
                                  'recipient@example.com'))

payload = '''This is the body.
From (will not be escaped).
There are 3 lines.
'''

mbox = mailbox.mbox('example.mbox')
mbox.lock()
try:
    msg = mailbox.mboxMessage()
    msg.set_unixfrom('author Sat Feb  7 01:05:34 2009')
    msg['From'] = from_addr
    msg['To'] = to_addr
    msg['Subject'] = 'Sample message 1'
    msg.set_payload(payload)
    mbox.add(msg)
    mbox.flush()

    msg = mailbox.mboxMessage()
    msg.set_unixfrom('author')
    msg['From'] = from_addr
    msg['To'] = to_addr
    msg['Subject'] = 'Sample message 2'
    msg.set_payload('This is the second body.\n')
    mbox.add(msg)
    mbox.flush()
finally:
    mbox.unlock()

print(open('example.mbox', 'r').read())

读取mbox邮箱

# mailbox_mbox_read.py
import mailbox

mbox = mailbox.mbox('example.mbox')
for message in mbox:
    print(message['subject'])

从mbox邮箱中删除一封邮件

# mailbox_mbox_remove.py
import mailbox

mbox = mailbox.mbox('example.mbox')
mbox.lock()
try:
    to_remove = []
    for key, msg in mbox.iteritems():
        if '2' in msg['subject']:
            print('Removing:', key)
            to_remove.append(key)
    for key in to_remove:
        mbox.remove(key)
finally:
    mbox.flush()
    mbox.close()

print(open('example.mbox', 'r').read())

创建一个Maildir邮箱

# mailbox_maildir_create.py
import mailbox
import email.utils
import os

                                    'author@example.com'))

                                  'recipient@example.com'))

payload = '''This is the body.
From (will not be escaped).
There are 3 lines.
'''

mbox = mailbox.Maildir('Example')
mbox.lock()
try:
    msg = mailbox.mboxMessage()
    msg.set_unixfrom('author Sat Feb  7 01:05:34 2009')
    msg['From'] = from_addr
    msg['To'] = to_addr
    msg['Subject'] = 'Sample message 1'
    msg.set_payload(payload)
    mbox.add(msg)
    mbox.flush()

    msg = mailbox.mboxMessage()

    msg['To'] = to_addr
    msg['Subject'] = 'Sample message 2'
    msg.set_payload('This is the second body.\n')
    mbox.add(msg)
    mbox.flush()
finally:
    mbox.unlock()

        print(open(fullname).read())
        print('*' * 20)
