I am testing various mails sent by my app (on localhost with Postfix

- OS X of course…)  
no proble when postfix is running…

but if Postfix is not running I don’t have any raised error…  
I tried using the NET lib…

rescue Net::SMTPFatalError, Net::SMTPServerBusy, Net::SMTPUnknownError,  
Net::SMTPSyntaxError, TimeoutError

no matter cannot get an error…

any info or link will be welcome… (especially on net lib…)

thanks
