Configure the Folder Auto-clean Feature

The folder auto-clean feature in SmarterMail is designed to help Email administrators keeping mailbox size(s) under control. Using folder auto-clean, common folders like the Junk E-mail, Sent Items and Deleted items can be regularly purged of old messages so they do not clutter user mailboxes. Email administrators can configure folder auto-clean to allow users and domains to override suggested settings or to require them to follow set policies.

Follow these steps to enable the folder auto-clean settings on the domain level:

1. Log in to the SmarterMail web interface (http://webmail.yourdomainame.com) as the domain administrator.
2. Click the Setting button.
3. Click Domain Settings
4. Under Filtering, click the Folder Auto-Clean button.
5. Click the toggle to enable override for this domain.
6. Click the New Rule button.
7. First select the folder you'd like to apply folder auto-clean functionality to.
8. Under the Type drop-down menu, select a trigger for this rule. Here you'll select the size of the folder you'd like to maintain, or a period of mail you'd like to retain.
9. Add the trigger size or period of days.
10. When finished, click the Save button.
