There are a number of examples of using a Firebase Cloud Function that triggers on user creation or deletion (see here) to send an email (potentially using a 3rd party service).
I'm looking for a way to send Email address verification, Password reset and Email address change messages through a 3rd party email service as well.
Is it possible to either configure that in Firebase's console, or can the default action of sending these messages through Google's own email service be disabled and some Firebase Cloud Function trigger be used to replace that functionality with a 3rd party email service?

How could I use Google Compute Engine (or a similar service, like AWS) to send email on behalf of users via their SMTP server?
I am interested in building an online email client which allows users to enter their SMTP and POP servers and send/receive email, like they would with their desktop clients. GCE blocks all SMTP ports to prevent abuse and recommends using a mail service like SendGrid instead. However, after researching dozens of these services, they all seem to only support transactional email using their own SMTP servers, or possibly a pre-cleared smtp server. I simply want to send email using the user's SMTP server (ex smtp.mail.yahoo.com), just like they would if they were using a desktop client.
I realize I could host my own servers but I am not interested in maintaining the infrastructure. I would like to host everything on a cloud service. Is there any way I can work around Google's restrictions with an existing service?
As I'm sure you are aware, you would have to have the user enter their SMTP server information and account credentials. You would then use that information to connect to their SMTP server.
By default AWS EC2 instances have SMTP traffic on port 25 rate limited. To remove this limitation, you would need to fill out and submit the following form:
https://aws-portal.amazon.com/gp/aws/html-forms-controller/contactus/ec2-email-limit-rdns-request
If you're looking to send mail as a Gmail, Hotmail, or Yahoo user, you'll probably want to call the service's API to have the server send mail on the user's behalf. There are several benefits of this:
You'll need to get authorization from users (usually via an OAuth flow)
in order to access their mail. This means that users shouldn't be
surprised that you're sending mail from their accounts, and they'll
have some control over your access.
The mail will be signed and come from the appropriate IP addresses to
comply with the various spam-control mechanisms set up by those
companies. Without this, it's likely that the mail you send will end
up in the bit-bucket of the recipient.
By using the API, the service should be able to keep a copy of the
sent mail in the user's outgoing mail folder. This will let the user
see and search for the original message sent if they want.
Unfortunately, this may also mean that each mail service you want to send from will need separate integration, and that you may not be able to send as the user's email address from smaller providers.
Note that the App Engine mail API allows you to send mail as the currently logged-in user (when logging in, users have a similar consent screen to the OAuth process mentioned above).
For a project I need to setup either a mail server (like Open X-change, Kolab) or I can use email service as Saas from providers like Mailgun, Sendgrid etc. But my prime requirements are:
Create new email addresses using (Rest) API or any other API programmatically.
Ability to create huge number of email ids (more than 10,000)
I have researched and found some like mailgun provides facility of sending / receiving messages through APIs. But nothing was mentioned about creating new email ids using APIs.
Does anyone know any mail server / SaaS which provides the aforementioned facilities?
To have a mail id, you need to be able to accept messages at that location, which would be a full mail service such as Gmail.
If you just need to send "as" addresses, you can use an SMTP service such as SendGrid. You'd just need to make sure the domain is legitimate and can receive mail, and that you set the Reply-To value to something that you can accept mail at.
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

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.
Here is my issue, I'm creating a website with a little login and resetting password. It's basic stuff, when user forget the password they can click the link and my application will send an email with a link to reset the password. Now, I'm using Google App to send/receive email so I created a new alias like noreply#company.com.
And I just got a confirm email from Google that I'm not allowed to use Google Server to send out email by JavaMail, because they do not support JavaMail as a mail client, the issue that I'm having is I'm getting AuthenticationException back from smtp.google.com.
Moreover, I'm using Amazon EC2 to host the application as well, and amazon provides SES service to send out emails. So, the question would be can I use Google App to host our company email for every employee, but can I still use Amazon SES to send out emails by JavaMail within the same domain name as we are using with Google Apps?. So, the emails that we'll be sending out would be noreply#company.com but will be from Amazon SES.
I'm not sure if I'm making this clear enough, my concern would be we redirect email MX Record to Google App already, I think we cannot redirect to Google and Amazon at the same time?
The application we are writing is based on Grails, so the email would be from Spring Email
Cheers,
Based on my usage of Amazon SES, you should be able to use the configuration you are suggesting without any issues. You do not need to add/change any MX record when using SES, because SES does not allow you to receive emails. It is only a service for sending (relaying) email messages, i.e., as far as I understood your needs, it will serve you perfectly, and your source email address will be the same as you use today.
When you sign up for SES and want to start sending test messages, you need to verify your source and destination email addresses before actually sending emails. You can achieve this verification through either scripting (ses-verify-email-address.pl) or API (VerifyEmailAddress on AWS SDK). After sending the verification request, you should receive an email address on the verified account. Just follow the message instructions and you can safely send some test messages.
When you are satisfied with your testing, you should request production access, and after this step, you no longer need to perform verification on destination e-mail addresses.
In order to call the API, I think you can use the AWS SDK for Java without problems in your application.

i want to this:
When a new user want ta register to my site, he/she must enter GSM number on registration form
and activation code sent with a SMS message and e-mail.
he/she must enter SMS activation code and e-mail activation code for complete joomla new user register process.
Is this possible? Can i do that?
yes, But you have to think a lot about integration your implementation with Joomla.
You have 2 approaches to send SMS messages.
1. Using a GSM modem
Here you will need dedicated hardware to do this. You will need a GSM modem + A dedicated server/machine. You have to write to the serial port using appropriate language and use AT commands to send sms messages. Here the advantage is everything is yours so you have total control over everything. You will be able to find a cheap mobile service provider for this.
2. Using an SMS Gateway
Based on your requirement of integrating this with Joomla, this might be the easy approach. In this way you have to send http, https request to a certain URL with the message information and authentication details. The gateway will handle the rest. Alternatively you can choose SMTP as gateway protocol and reuse your email implementation. When you send an email to a certain preconfigured address it will generate an SMS with contents of the email message.
Clickatell is an example for such service providers.
