Email settings invoiceninja

Good afternoon, trying to configure in the panel the subject of sending email “Email Settings” sends me an error at the moment of the test that is the following:

“Address in mailbox given [] does not comply with RFC 2822, 3.6.2.”

As I can solve the problem since I can not send any mail and I can not add new users.

Email Settings

Not sure if this is the problem but the ‘From Address’ should be an email address not an URL.
