I receive the following error:
Mailer Error: SMTP Error: The following recipients failed
This error is displayed after successfully ordering a product during the checkout process on my Multi-Vendor platform.
Other emails have been sent successfully; the error is only displayed during this particular thing.
The problem continues to persist even after changing to an offline payment processor, to check if it was my payment gateway causing the issue. It is definitely something with Cs-Cart itself.
Anyone have any idea how to fix this?
