Outbound email configuration. Different sending addresses with different servers

Question

We have an issue to solve to operate as well in our Country (Italy).

Any organization in our Country must use Certified Email (https://en.wikipedia.org/wiki/Certified_email) to send fiscal and official requests to public organization. This create a config problem inside CiviCRM, which I try to explain:

1. we must use more than one address to outbound email
2. the normal address can send all, using the normal and easy configuration
3. the Certified Email address must use IMAP and the specific server to send messages
4. we didn't find a possibility to configure this difference
5. there are more than these problems to manage inbound email.

Any idea to solve it? TIA

Answer 1

I am not sure if all this is possible in current version of CiviCRM

#1 - Yes, one can define and select From Address for sending emails.

#2 - CiviCRM sends email using settings defined in Outbound Settings.

#3 - There is no such way where one can specify outbound settings based on from address. But this is possible by creating extension that would create a settings page for each from address to save in civicrm_setting table and then have [hook][1] to alter the mailer setting before sending emails.

But i would still prefer you to wait for other people to provide solution.

Answer 2

If I understand you correctly you need to determine routing of some outbound email based on the recipient. This is not a core functionality of CiviCRM.

Outbound, by extension

CiviCRM allows extensions to implement hooks, and I think for your needs the appropriate hook would be hook_civicrm_alterMailer().

This hook is called when CiviCRM prepares an email driver class to handle outbound message delivery.

The documentation linked above for this hook gives example code to deliver emails to a logfile instead of via SMTP. Creating an extension which implements this hook and routes email to your CEP server when required would hopefully deliver the outcome you need. If open-sourced, this would be available to other organisations with the same requirements, which is a great outcome.

Outbound, in MTA

Some mail servers (MTA) allow you to customise routing based on destination. If you control your hosting environment, you might be able to instruct an MTA to route emails for some recipients to be delivered via one channel (SMTP to a specific CEP service, or add headers to CC/sign per requirements), and others via default SMTP routing. An MTA could query for the correct behaviour based on destination email against CiviCRM's HTTP API.

Inbound

If you need to handle this on the inbound channel (when your organisation receives email), it's possible to configure multiple mailboxes to check in CiviCRM. This is done at Administer > CiviMail > Mail accounts and has documentation in CiviMail incoming mail setup and CiviCRM inbound mail documentation.
