[TriEmbed] Simplest way to send e-mail from Python? Carl?

Shane,
My recommendation is to load postfix and send it through gmail. Here is a tutorial, but there are many more tutorials showing the same type of set up. Postfix is now loaded by default on RedHat 7 and IMHO, far easier to set up than sendmail. Don't think this is the only setup option, it was just the first tutorial I saw, but it is pretty much the type of configuration I use.

 Shane,The Ruby code is just saying it's from a gmail account. It's not actually sending the email through gmail. It must be using a local mail server. In any case the RPi is the source machine. The reason you don't need a password is that you are already logged into the source machine and that machines email account. All shell accounts are essential an email account.I'll try to cobble together an MTA (mail transfer agent) for you in the morning. It won't have all the bells and whistles in it but it should work.Carl

Carl,
I follow about setting up a local mail server to send the outgoing mail. I was just trying to duplicate the function of the Ruby code snippet, which appears to send e-mail via Gmail without validation. The Ruby code is running under Mint on a VM on my desktop that I am pretty sure does not have a local mail server installed.
I am migrating the task from Ruby/Sinatra to Python/Flask and plan to host it on a Raspberry Pi A+. It is actually running on the Pi now, just without the e-mail component. My only reservation about switching to SMS is that it would require a pay service as apposed to being able to do everything so far using free accounts.

Shane,
As I said in the 2nd email I sent, it looks like you just want to send an email to any address, correct? If so this is no big deal, but you need pop3 setup on your local machine. If it is, then you should be good to go. Most emails that are not secure go to port 25 and use the SMTP protocol, they are sent on port 110 with the pop3 protocol, so if you are only sending then you only need pop3 setup. Then any simple client can be used to send the email.
Am I understanding your issue or am I out in space somewhere?

Carl,
Back in the day you could send e-mail without validating user credentials on the outgoing mail server. I spoofed a sender's e-mail address (demonstration as proof of concept) for a message going through the servers at Oak Ridge National Lab in the mid 90's so it was common practice back then. Sending without validation is the only thing that I can come up with to explain how or why the Ruby snippet works. But it does work. It's part of a project to use SMS to trigger and log events using Twilio and Gmail and IFTTT and Google Drive (kind of an Internet of Things: Duct-Tape Edition!)
I would rather have a token or credential to validate for the outgoing mail server if validation is unavoidable. The thought of having my password setting in a directory in clear text gives me the heebee jeebees. I may use SMS for communication if I cannot figure out how to send e-mail without the clear text password.
Thanks for chiming in! I would much prefer to start with an expert opinion rather than have to sort through a mountain of Google hits!

Shane,
The only way to not send a password in clear text is to use one of the secure mail transports using either port 587 or 995, both are different and independent of programming language. The client in Python is quite easy, and I have written many in the past. The Ruby code snippet would need to use one of the two ports above in order to be secure which can be done in any language. Also the receiving end must support the one you choose or you won't even get a connection.
>From the code I see above that would send everything in clear text. To not send a password or even use one would mean there was no password on the account, which I don't believe. So, I'm a little confused here as to what is happening.

I want to send e-mail from Python. The code below sends e-mail from Ruby and does not require having your e-mail password in clear text. 
require 'mail'
    Mail.deliver do      from      'user at gmail.com'      to          'trigger at recipe.ifttt.com'      subject  '#1235'      body     "Request from: #{name}."    end
Is there a similar way to send e-mail from Python without requiring your e-mail password in clear text in the code?
Thanks,Shane
