Service of type Nette\Mail\SmtpMailer not found – Nette 2.3

Zdravím,
provedl jsem upgrade a Nette 2.3 a začlo mi to házet problém s DI. Konkrétně:

Service '105_Exsys_Email_EmailService': Service of type Nette\Mail\SmtpMailer needed by Exsys\Email\EmailService::__construct() not found. Did you register it in configuration file?

díval jsem se na namespace a měl by být OK. Ještě radší přikládám composer.json:

		}
