parsing long `To' and 'Cc' from email

[Gerardo Herzig]

Hi all. Im trying to develop yet another email filter. Just for fun for
now. Im having a little trouble parsing long 'To' and 'Cc' headers.
Sometimes p.e. the 'To' header comes like

'a*******@site.com, ac*****@site2.com'
others comes like
'"My self" <my********@self.net>, "My brother" <br*************@self.net>',
other times a \r\t comes inside the `To' header. And any combination of
the above mentioned (and shurely more) can ocur.

the email.* package dont seems to parse that kind of headers
`correctly'. What i want is to get a list with all the email address in
the `To' header.

Someone know if there is a more sofisticated parser for doing this?

Thanks!
Gerardo

If you're not interested in parsing the entire email message, you may
just want to run a regex on the message itself, looking for the "to"
header.

Here's a good start:

r"^to:\s*(.*)$"

You'll want to use the multi-line and case-insensitive options when
you use it.
