procmail in python

Procmail is very powerful, but it's configuration format is really terrible.

This program replaces it with Python, so you can put email processing rules to `~/.mailprocrc` in a nice pythonic way.

The script provides a set of modules (`subprocess`, `os`, `sys`) and variables (`message` and `mbox`

for current message being processed and current user's mailbox file), as well as helpers

(`default_process()` function for fallback processing),

so you can start writing your `~/.mailprocrc` file immediately without a lot of boilerplate code like bunch

of `import`s in the beggining.

All you have to do is just analyze `message` (an `email.message` object) and act on it, and call

`default_process(mbox, message)` if you want to fall back to default action.

Example:

```python

ATTACHMENTS_DIR = os.path.expanduser('~/mail')

LINK_RE = re.compile(r'(?:ht|f)tps?://\S+', re.I)

if message['content-type'].startswith('multipart/mixed'):

    mkdir_p(ATTACHMENTS_DIR)

    for msg in walk_message(message):

        if msg.get_content_type() not in ('text/plain', 'text/html'):

            filename = os.path.join(ATTACHMENTS_DIR,

                    os.path.realpath(os.path.sep + msg.get_filename())

                        .strip(os.path.sep)

                        .replace(os.path.sep, '-'))

            if not os.path.exists(filename):

                with open(filename, 'wb') as f:

                    f.write(msg.get_payload(decode=True))

elif 'download' in message['subject'].lower():

    subprocess.Popen(['/usr/bin/wget', '-P', os.path.expanduser('~/downloads'), '-i', '-', '-nc'],

        stdin=subprocess.PIPE

        ).communicate(

            '\n'.join(

                link.group(0) 

                for msg in walk_message(message)

                for link in LINK_RE.finditer(msg.get_payload(decode=True))

                if msg.get_content_type() in ('text/plain', 'text/html')

            ))

else:

    default_process(mbox, message)

```

Or you can use more strict/functional way if you like:

```python

@recipe(lambda m: m['content-type'].startswith('multipart/mixed'))

def save_attachments(mbox, message):

    pass

    

@recipe(lambda m: 'download' in m['subject'].lower())

def download_links_from_email(mbox, message):

    pass

```

In the second form you don't have to call `default_process()` manually, it will be called for you if none of your recipes match your message.

Example of opensmptd config (`/etc/smtpd/smtpd.conf`) to use mailproc:

```

accept from any for domain "home.kstep.me" alias  deliver to mda "/usr/local/bin/mailproc.py"

```
