How to tell if I can send emails from Ubuntu

  • 772

I am developing some software using Ruby on Rails in Ubuntu. I added Ruby's native mailer library, but it isn't sending mails so I want to make sure that my OS is not prohibiting that.

How can I test the ability of my OS to send email?

I got this system output:

telnet mx0.gmx.com 25
Trying 74.208.5.90...
Connected to mx0.gmx.com.
Escape character is '^]'.
220 mx0.gmx.com GMX Mailservices ESMTP {mx-us011}
EHLO
250-mx0.gmx.com GMX Mailservices
250-8BITMIME
250-ENHANCEDSTATUSCODES
250 SIZE
ubuntu email ubuntu-10.04

    Use the following command to connect to a valid mail server:

    telnet server.com 25

    At the prompt type "EHLO". If you get a response, you're good.
