We've had a bounce processor set up (and working) for about 2 years. Recently, I'd guess the last two months I'm not exactly sure when this started, it has not been fully working.
I can see the bounced messages arrive in the bounce email account. After the Bounce fetcher runs (we have it set to run hourly) it moves the emails to the processed folder. What it does not do is then mark the emails on the contact records as bounced.
The scheduled job log shows no errors.
Full message: Finished execution of Bounces fetcher with result: Success (1)
We are in Drupal 7, CiviCRM 5.27.7.
Has anyone else experienced this? I'm not sure where to poke around next to find out where the breakdown might be.
