How to adjust the anti-spam (Junk Mail) auto-clean interval

This document will explain how to change the interval of the Anti Spam Auto-Purge feature for the IMAP folder 'Junk Mail' and when this purge action occurs.

MailSite 6.1.22 and later allows you to configure this parameter via the MailSite console and does not require you to make this registry/database change.

The default value for the Auto-Purge for the folder 'Junk Mail' is for messages that are older than 30 days. This value is calculated on successful logout from an IMAP session. At this point any messages that are older than 30 days from the time of logout will be removed from the folder 'Junk Mail'.

The Registry and the SQL Connector implementations are configurable and below are how to change the values.
