Selecting delivery server for transactional email

[Jeroen Verschoor]

I've tried some settings, but cannot find out how to do so:

For a specific client, with a specific domain let's say 'clientdomain.com', we've got specific transactional emails.
It is needed to sent these specific transactional emails over a specific delivery server. Other email should sent over the 'standard' delivery service for that customer.
We sent transactional email using the 2.0 API

As far as I can see there is no option to select a specific delivery server through the API call.

How can we achieve the above so that, for a selection of (transactional) emails, we can select a specific delivery server?

Doesnt it work to create a delivery server only for transactional emails, and assign that server to that customer, so all transactional emails for that customer go out using that server?

Maybe it does, but it is needed to only sent this specific (transactional) mails over a specific delivery server.
The case is: invoices need to be sent over a more secure (and expensive) environment, others can use the regular delivery server

For these invoices (also for other transactional emails) we use the transactional email API
Only uniqueness is the domain which is sent from, this domain differs from our other sendings.

Can we set the selection of a delivery server purely based on the mailFrom domain used (so that MailWizz sents all email with a specific domain used in the mailFrom from that server while we exclude it in the other delivery servers) OR as a setting while sending the email through the (transactional)API?
