Hello.
We have as incoming mail servers:
- Gmail for normal emails.
- Aruba for electronic invoices.
As outgoing mail servers:
- Aruba for electronic invoices.
- Sendgrid for newsletter (configured in "Email Marketing->Configuration->Settings").
We want Sendgrid to handle ONLY emails sent with newsletters, but actually it handle ALL outgoing emails (apart aruba ones). All emails that are not newsletters should be handled by Odoo mail server.
Is it possible?
