Notifications loads wrong user tokens when submitting mail.

When the email is send about notifications of the content the mail is send to the correct user but the tokens like [name] are replaced for a completely different user.

For example:
"For a message: Notification for node for user username1"

it comes for user

"For a message: Notification for node for user username2"

The website using the module has also Varnish enabled. The notifications are sent via cron and not immediately. The version of the Messaging module is 6.x-4.x-dev and Token module is 6.x-1.x-dev.

Does anybody have any idea why this can be? Any help would be appreciated
