Hi!

I'm trying to use the mass mailing tool in 7.0 version.
I've defined an smtp authentification and it seems to work.

I use this trick: https://www.odoo.com/fr_FR/forum/help-1/question/how-to-send-email-to-each-contact-2392

If it works for 30 customers, for 4000, it doesn't work at all and I have those error messages:

2016-01-15_15:04:56.01868 Traceback (most recent call last):

…

Is there a way to tell to openerp sending email in batch mode or other solution for this problem?

Bye!
