For cPanel & WHM 11.48
(Home >> Service Configuration >> Service Manager)
This interface lists your server's TailWatch Drivers, and allows you to perform the following actions on them:
- Enable TailWatch Drivers.
- Enable daemons.
- Monitor enabled daemons via The cPanel Home Interface.
This TailWatch driver enables support for IMAP and POP3 before SMTP authentication. This configuration allows a user who authenticates against the POP3 or IMAP service in the last 30 minutes to send emails via SMTP without the need to authenticate again.
All users who share that authenticated user's IP address also receive SMTP authentication. As a result, this option is less secure than password authentication.
As of cPanel & WHM version 11.32, this setting defaults to disabled. We recommend that system administrators use SMTP authentication, because most modern mail clients now support SMTP authentication.
