CentOS - Apr 2010 - Sending mail from CLI to another SMTP host

Hi all,
Is it possible to send mail from CLI (bash, python) without any LOCAL
SMTP installed, using SMTP on another machine.
Care to give a glimpse of the code?
Thank you.

One approach

step 1: make sure packages 'expect' and 'telnet' are installed
step 2: read: man autoexpect  and RFC 2821
... see worked example for handing email to a remote server
 	http://www.owlriver.com/tips/sendmail-tip/
 	http://www.owlriver.com/tips/trace-sendmail/
step 3: experiment to taste in talking the protocol.  'expect'
 	and autoexpect makes it trivial to build a script that
 	works

But of course, just cause the smtp server you are pointed at initially
is local, interpret that as 127.0.0.1. So point to another. Most home
users don't have their own smtp server, they use their isp's...

http://heirloom.sourceforge.net/mailx.html

"Supports SMTP to send messages directly to a remote server. A local
 sendmail interface setup is thus not necessary."

Personally, I'd use the default Centos install of sendmail because it's
there,
it's easy, and it works the way mail has been intended to work for decades. 
The
default setup is to accept only from localhost, but send anywhere. If you want 
to relay through a known host, configure SMART_HOST in /etc/mail/sendmail.mc and
restart the sendmail service.  Then your scripts and other programs can simply 
run sendmail to queue/delivey instead of doing it themselves, and can deliver to
local recipients as well as remote.

If you really don't want a mailer and are ok with failures or want to handle
queuing and retries yourself, the epel repo has perl-Mail-Sender which is a 
fairly complete smtp send-only client.  After installing use perldoc or 'man
Mail::Sender' to see the documentation.

install perl, Net::SMTP, MIME::Lite and Email::Valid and
read the manuals which give very simple examples on how to do it
e.g. man Net::SMTP

The enclosed script works for python 2.5 (it's an example.)

If you don't use the localhost sendmail, then you'll have to relay
through another sendmail server - and good luck with that.

Maybe you can relay through a Google?

#!/usr/bin/env python

import smtplib

def prompt(prompt):
    return raw_input(prompt).strip()

fromaddr = prompt("From: ")
toaddrs  = prompt("To: ").split()
print "Enter message, end with ^D (Unix) or ^Z (Windows):"

# Add the From: and To: headers at the start!
msg = ("From: %s\r\nTo: %s\r\n\r\n"
       % (fromaddr, ", ".join(toaddrs)))
while 1:
    try:
        line = raw_input()
    except EOFError:
        break
    if not line:
        break
    msg = msg + line

print "Message length is " + repr(len(msg))

server = smtplib.SMTP('localhost')
server.set_debuglevel(1)
server.sendmail(fromaddr, toaddrs, msg)
server.quit()
