Try this way.

Create a file called popBeforeSmtp inside the folder Extensions ( in 
the root directory of your zope installation ).
Add this content:

import poplib

def popBeforeSmtp():

   M = poplib.POP3('your.mail.server.org')
   M.user('yourUserName')
   M.pass_('yourPassword')

Then instantiate an External Method called mailAuth in your Zope site 
- accessible by the script that sends mail, and root folder is good 
for this purpose - which uses the function popBeforeSmpt.

Before each invocation of send method against mailhost to send mails 
call the external method mailAuth.

Hope this help.
