I use Jira servicedesk and the xxx.atlassian.net mailadress. In Documentation I found instructions that Email processor filters the emails using information stored in the database. But no information about how to manage it. I have and had the Email processor enabled. What to do more?
"Manage global mail settings
There are two global mail settings - email puller and email processor - that are used only by JIRA Service Desk and do not impact any email settings you have set up for JIRA. Email puller connects to your mail servers every minute and pulls the email data into the database. Emails with attachments larger than 25MB will not be pulled. Email processor filters the emails (e.g. to remove auto-replies and spam) using information stored in the database.
You can access these settings by going to > System > Global mail settings."
