Postman has been handling the Mail Delivery nicely for a long period now on a clients site.
Yesterday there was problems with the contact form sending emails.
The problematic emails say in the log:
We’re sending using the Gmail API (oauth). I’ve logged into the Developer API panel in google, and can’t see any errors or reasons why it might have been having problems.
The diagnostics tools inbuilt into PostMan all seem to report with good results, and testing the form today all seems well.
Not sure why the contact form stopped yesterday, where could I look for clues?
Could it be the hosting environment blocked / throttled something?
