Sending email from rails, without an email server installed?

Rails

Is there why to send email from a rails app which does not requires
the installation of an email server such as postfix or sendmail?

Yes.
you can use smtp. See the api docs for ActionMailer on how this is done.

I wrote a tutorial on this a while ago that might be useful to you:
