Unable to replace alias "smtpd" with "swiftmailer.mailer.default.transport.real".

[krewmarco]

I'm running:
symfony 2.2.-dev
symfony/swiftmailer-bundle dev-master f5e5d12 (v. 2.3.4)

Once I set
swiftmailer:
disable_delivery: false

I get these errors:

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
Unable to replace alias "smtpd" with "swiftmailer.mailer.default.transport.real".

[Symfony\Component\DependencyInjection\Exception\InvalidArgumentException]
The service definition "smtpd" does not exist.

if I replace my "transport" with "gmail", I get the same error but with "gmaild".

Thanks,
Marco

Can you paste your swiftmailer configuration (without the credentials of course) ?
