Rails sending mails with actionmailer from an virtualbox vm -

i have debian vm running in virtual box on windows machine.

in vm rails application running, should send mails action mailer.

i've set action mailer credentials in application.rb

but when mail should send there nothing in mailbox ... seems mail isn't send or dosn't leve vm.

what check if mail send properly?

in development environment need these options in environments/development.rb

config.action_mailer.perform_deliveries = true config.action_mailer.delivery_method = :smtp 

by default rails in development mode shows email body in log without real sending.
