October 19, 2020

Features

The new Enable Remote Search parameter enables email search and filter for IMAP protocol configurations at the server-side when a matcher is used with the On New Email - IMAP component. Enabling the parameter decreases traffic by reducing the number of emails sent to the client-side for processing, which reduces the amount of time and resources required to process polled emails.

Fixed Issues

The IMAP protocol configurations are not applying filtering on the server-side, resulting in large amount of emails downloaded from the server. (EMAILC-54)
