how I can check if spool is enabled via configuration?
In Swift_Mailer, I have a transport object and spool - but of course is private, in config:
swiftmailer:
url: '%env(MAILER_URL)%'
spool: { type: 'memory' }
spool - is not readable for other classes.
I need that info to report the sending user that their message has not been sent, but it has been spooled.
