Transactional post-donation email reports failure, actually delivers mail
Created by: universalhandle
Upon making a test donation, I get the following error message:
An error occurred when CiviCRM attempted to send an email (via SMTP). If you received this error after submitting on online contribution or event registration - the transaction was completed, but we were unable to send the email receipt.
The mail library returned the following error message: Sparkpost error: HTTP return code 200. Check https://support.sparkpost.com/customer/en/portal/articles/2140916-extended-error-codes for interpretation.
This is probably related to a problem in your Outbound Email Settings (Administer CiviCRM » System Settings » Outbound Email), OR the FROM email address specifically configured for your contribution page or event. Possible causes are:
Your Sendmail path is incorrect. Your Sendmail argument is incorrect. The FROM Email Address configured for this feature may not be a valid sender based on your email service provider rules. Check this page for more information.
However, the mail is delivered.
CiviCRM version: 4.4.21. CMS: Drupal 7
I haven't dug into this yet. Just logging it so I don't lose track.
