Hello there. I have a problem with sending e-mail notification.

I have 2 e-mail boxes in my odoo (support@... and info@...) When customer sends e-mail to info-box, user with id 1 is owner of the lead, users with id 2,3,4 are followers. It's implemented via Server Action ( python code: 

object.write({'user_id': 1})

object.write({'message_follower_ids': [(6, 0, [2,3,4])]})

I need to add a functionality to send e-mail to this people while creating or uppdating customer. 

Can someone help me?

Thanks in advance.
