Allow users to send e-mails through a Rails app - email

I'm currently trying to make a Rails 4.1.1 app that allows users to send custom newsletters. I'd like to do this without asking for the user's mail account password if possible.
I just need it to appear as if the mail was sent from the specified e-mail address. Is this an unreasonable/impossible requirement? Is there any kind of service that can help me achieve it? Are there any common strategies for sending e-mail on a user's behalf?

Proper Way to Programatically Send Mail Using Google Apps

I have a domain which uses Google Apps for Business to handle email. I already have it mostly set up--MX records point to the correct location and my domain is verified.
I'm now writing a python app (with Django) that will need to serve mail from my domain. What's the correct way to do this with Google? Should I create a Google Apps "user" for the organization as a whole, and then authenticate via SMTP as that user and send mail from there?
The Gmail API says that it
is the best choice for authorized access to a user's Gmail data.
and that
Automated or programmatic message sending
is a typical use case. However, I'm not trying to access a user's data or send mail on behalf of a user, but on behalf of my domain. What's the correct way to proceed?
Any help much appreciated!
You could use SMTP or the Gmail API based on your description. In both cases, you'll need some sort of service account to send mail from. With SMTP, as you mentioned, you'll be authorizing via the instructions you linked.
If you choose to use the Gmail API route, you'll be authorizing the API usage with the account. The Gmail API has many other use cases (e.g. to access user's data) but you're only using it to send emails on behalf of a service account you control.

Quickblox, send email to new users to validate email address

I'm new to quickblox MBaas and I would like to send out an email (to verify e-mail address) to a specific user when he signed up. Is there a standard procedure for this or a way to do this in Quickblox. Many thanks for your help.
There is no a way to do this for API users right now.
The cause of this solution is that it's quite hard sometimes for mobile users to verify an email. Just imagine a situation where user doesn't have a ready for use mail client on his device - then there is no a way to verify an email in this situation.
Other cause is that email verification can complicate your onboarding process.
It's possible to send a greetings email. You can setup it in Admin panel, Users module, Settings tab

How to provide tenants in SaaS application with their #companyName.application.com specific email services?

In our SaaS application each company (tenant) is given their custom domain like companyName.ourapp.com
We would like to provide some email services like:
Ability to send and receive email notifications from info#companyName.ourapp.com and similar addresses
Ability to create new email accounts in clients' subdamains at runtime, programmatically, when needed. For example we would have separate emails created for each "opening" so that emails sent to this address would be parsed info would be extracted
Similar tasks
For now I just don't even know on where to look and how this could possibly work.
As far as I understand email it should be some kind of custom mail server (SMTP) serving all sub-domains and having API we can use to send emails, list and retrieve messages etc.
Please suggest how it may work and is there any components out there we can use to implement this.
There are three options for this.
Create an email server and programatically configure it to accept or deny the specific accounts. Then use cron to poll via pop3 or imap and download the messages for the account. You can then send them on for the customer or handle them in your web app.
Create a script that is fired by the email server as it receives each email. The script can then handle what to do with the email as it's received.
Use a third party to receive the email via HTTP Post at your app. Using CloudMailin for example would allow you to create a custom authorization filter that would call your app in realtime and determine if the given account exists and messages should be accepted for it.
I wrote a blog post for Rails about receiving incoming email, however the principals would apply to any programming language and framework.

Automatic email from iphone application

I have seen some similar questions here on stack-overflow, but in my application i want when user click on confirm button automatic email go to the email id specified in the form with other details.
How can i implement this.
You could just make a post request to a server and have the server then send the email.
You cannot send emails automatically without sending the user to the mail application. You could however, take advantage of a third party service like Amazon Simple Email Service http://aws.amazon.com/ses/ to send the message.

detect if given Email ID is configured in Mail?

I am creating a mail app. I am using MFMailComposeViewController. I am able to check whether the mail client is configured with any of email or not. But can I check that the mail client is configured by a particular email account.
I want to force user to first setup his mail account and then try to send mail. For that I need to check if user is trying to send mail from abc#gmail.com then it should be configured so is it possible to check that if iphone's Mail app is configured by given email.
If possible then how and if not then any alternatives..
Thanks a lot.
The API doesn't expose that information publicly (for probably good reasons, such as preventing developers from harvesting iPhone users' email addresses).
