Disable swiftmailer spool in Symfony per environment

php, swiftmailer, symfony, yaml

Solution

Apparently the only way to disable email spooling is to completely leave out the spool entry from your configuration file. Once you include the spool entry in the main configuration file, there is no way to disable spooling for a specific environment.

That said, you can accomplish the opposite of what you propose: you can disable email spooling by default and enable it in specific environments.

Leave it out in `config.yml`:

swiftmailer:
    transport: %mailer_transport%
    host:      %mailer_host%
    port:      %mailer_port%
    username:  %mailer_user%
    password:  %mailer_password%

And include it in `config_prod.yml`:

swiftmailer:
    spool:     %mailer_spool_type%

Problem

I having trouble send bulk emails with symfony2 via console command. I want to disable the mail spooling complete for the env the console is running in but keep it working for the default env. So I have this in config.yml: ``` swiftmailer: transport: %mailer_transport% host: %mailer_host% port: %mailer_port% username: %mailer_user% password: %mailer_password% spool: %mailer_spool_type% ``` and then each env has it's on parameters like parameters_prod.yml: ``` parameters: mailer_transport: smtp mailer_host: smtp.someserver.net mailer_port: 587 mailer_user: "someuser" mailer_password: "somepassword" mailer_spool_type: { type:memory } ``` then for the console env I use parameters_cron.yml: ``` parameters: mailer_spool_type: ~ ``` The problem is using `~` or `null` doesn't actually turn off the spool but it uses the default values of `{cache: file, path: %kernel.cache_dir%/swiftmailer/spool }` Is there a way to disable the spool just by changing the parameters or is there a better way?
