Introduction

Mailnode is a simple Zope item that provides :

• A python module that can send mails with file attachments
• Another python module that can check an error mailbox and notify the application if the sending goes wrong

 

Configuration

In the 'properties tab' of the zope Mailnode object :

• from_address : expeditor email address
• charset : character encoding
• pop_server, pop_username, pop_password : error mailbox informations
• error_callback : name of the function called on error (by acquisition)
  

 

Synopsis

  Call structure in Zope (return a msg-id) :

      parameters = {
       'to': 'receiver@mail.com',
       'subject': 'Sujet du mail',
       'body': """Le corps du mail
                  sur plusieurs lignes""",
       'attachment': ['/home/user/document.pdf', fd2, 'fichier3.pdf', ...]
      }
      context.Mailnode.sendMail(parameters)

Errors control

In a second time, Mailnode can check periodically an 'error' POP mailbox, to take care of the sending problems.

  Concept :

• Periodically, an external program calls the 'check' method on the Mailnode Item, in Zope. (cron + wget)
• This method connects to the mailserver server and pops the error messages
• For every message, the msg-id is located by text analysis.
• The 'check' method triggers the method defined in the 'error_callback' properties, giving the msg-id as an argument.
