Google Calendar: Daily Emails Despite a Year of SMTP Rejections
Google Calendar is sending daily bulk email notifications to a spamtrap. The spamtrap was recently re-enabled after its timeout period, which means that for a period of over twelve consecutive months, it issued 500-level SMTP rejections to the daily Google Calendar email notifications. It is likely that this spamtrap years ago, when live, was subscribed to Google Calendar notifications. However, after a year of 500-level rejections to a daily bulk email, those emails need to have stopped. These did not, and are now spam. Google needs to fix its broken bounce processing for Google Calendar NOW.
