Hi Olu, This is not with Only one domain. There are more than one domain are getting this slowness or delay of receiving mails.
Per day my application is sending more than 2000 emails.One More thing I want to share my App Engine project is very old *since 2014*.I have Quotas of 20000 Recipients Emailed and 1,771,789 APIs calls (with APIs call Quota is 4,928 is per minute). So I think there is no issue in Quota. As I think Mail server of Google that is used in App Engine service is slow now a days. Can you share me about "prevent spammers" in document of App Engine where is it written ? GCP Support Engineers[1] is paid, so I asked this in this forum, Is there any workaround or is It really Google App Engine Mail Service is obsolete ? As you are saying it is deprecated, but as per documentation : https://cloud.google.com/appengine/docs/standard/java/mail "This page describes how to use a legacy App Engine service. Apps that use this service can only run in the Java 8 runtime" . My App is using Java 8. Please reply me what I have to do ?
