Test drive processor transactional email errors
I recently installed the Sparkpost extension and all the mail functionality seems to be working with all the test emails I have sent out via Mailings > New Mailing - mail processed on time, opens, click-thrus, and bounces counted correctly. We are just configuring CiviCRM for the first time and do not have a real Payment Processor in place. We are using the default Test Processor (type Elavon) to test out membership and donation transactions. The transactions go through and are recorded in the database. However, the acknowledgment emails are not working. We get the message:
The SparkPost service is unavailable due to a sending error, and the backup mailer is not enabled or not configured.
Is this due to the Test Processor, or are them some other mail configuration settings that need to be configured. Is this likely a SparkPost error or a CiviCRM configuration error?
We are running CiviCRM 4.7.10 (on WordPress 4.6.1) with CiviDesk SparkPost extension 1.1
Thanks for any help!
