SMTP Server Connection Errno ETIMEOUT


I am trying to test this simple program for sending e-mail using
‘net/smtp’ but not successful.
Can any one help me to indicate the issue I am facing here .

Note: I do not have any local SMTP server on my machine and I am trying
to connect a remote SMTP server which in this case is a

irb(main):001:0> require ‘net/smtp’
=> true
Net::SMTP.start(‘’,25,‘’,‘[email protected]’,‘XXXXXX’,:plain)
do |smtp|
irb(main):003:1* smtp.send_message
‘Hello’,‘[email protected]’,‘[email protected]
irb(main):004:1> end
Errno::ETIMEDOUT: Connection timed out - connect(2)

When I tried with different port 587 of then I get the
following error message.

et::SMTPAuthenticationError: 530 5.7.0 Must issue a STARTTLS command

If you have faced this error previously, please share with me your
solution as soon as possible.

Thanks in advance
