Out of office emails seem to be creating tickets in the application. Is there a way to stop this?
You need to configure the Spam Filter Settings in the Mail Server settings to exclude certain emails from being created as tickets.
Please goto Setup-->Mail Settings-->Spam Filter.
Define a rule on selecting Criteria from the drop down list and also mention the Condition.
Specify the filter content in the given text field by clicking Choose button.
Say, if criteria is 'Sender' and condition is 'is' then the content can be "mailer-deamon".
Click 'Add to Rules' button to add the criteria to the rules and match it with the incoming mails. Specify 'Match all of the following' and/or 'Match any of the following' option to match with the rule by selecting any of the radio buttons.
Click on Save.
