The following code works ok with Thunderbird and mail.app (at least with
all the mail I usually sent).

A friend of mine reports that he (with mail.app can see that he has an
attachment, open it, etc.)

import smtplib
from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders

class MailSender:
    '''Envia un mail con archivos attached.'''
    def __init__(self, server, remitente, to):
        self.server = server
        self.remitente = remitente 
        self.to = to
        assert type(self.to)==list

    def envia(self, subject, text, files=[]):
        assert type(files)==list
    
        msg = MIMEMultipart()
        msg['From'] = self.remitente
        msg['To'] = COMMASPACE.join(self.to)
        msg['Date'] = formatdate(localtime=True)
        msg['Subject'] = subject 
    
        msg.attach( MIMEText(text) )
        
        for file in files:
            part = MIMEBase('application', "octet-stream")
            part.set_payload( open(file,"rb").read() )
            Encoders.encode_base64(part)
            part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(file))
            msg.attach(part)
    
        smtp = smtplib.SMTP(self.server)
        smtp.sendmail(self.remitente, self.to, msg.as_string())
        smtp.close()
        return
