I noticed that submission confirmation email can be configured on the form level.
Is it possible to configure this on form space level? I would like to disable confirmation email for one of our form spaces.
if the same form is linked with multiple spaces the submission confirmation email would be sent no mater what space is a form submitted in. If you need to send the email for submissions from one space only you might need to turn off the auto-confirmation email, implement the email sender in a groovy script (Submission Completed Processor service) and add this custom logic in it.
Unfortunately there isnt any support for this config at the portal level only, eg all forms submitted via that portal will have submission confirmation emails sent.
For more help on how to send the email in the customized groovy service (SCP) see TM API Core SDK: com.avoka.fc.core.service.EmailService.sendFormConfirmationMessage(Submission submission, String toAddress)
or Emailer in the new Fluent SDK documentation
