Backup email notification is adding a space to the email address

When creating a backup on demand the email sent by the panel is adding a space to the end of the domain.

Subject: user → backup has been completed
From: Hestia Control Panel <[email protected]>
Date: 1/31/21, 12:50 PM
To: <[email protected] >

You can see the added space after the domain, which in turn results in

The mail system

<[email protected]_>: Host or domain name not found. Name service error for
name=domain.com_ type=AAAA: Host not found

Wondering if anyone else is experiencing this?
