What is SMTP?
Simple Mail Transfer Protocol (SMTP) is a set of commands
that directs the transfer of emails. When you send an email,
it will be forwarded from your email client,
(in this case this software Application), to the SMTP server, (in this case Gmail).
The server will then relay the mail to the recipient’s email server and a copy
of the email will be in the sent folder of your gmail account.
How to Use Google SMTP Server?
Google Gmail allows third party applications to access its SMTP relay service
In this section, we will show you how to send emails using
Google’s SMTP server.
Once your Gmail is up and running, change the following settings
in your Gmail account
Usually a "Quick settings" screen pops up
Click on the option to "See all settings" to expand the window.
There are a number of options in this section.
The only option you need to set, in this case,
is the "IMAP" option.
* * Don't forget to click on the "SAVE" button * *
NOW, we allow this application to have access to your Gmail account.
Depending on how you use google on your computer
The next screen can be different from one computer
to another.
Look for the section that deals with "Security"
Now look for the section that deals with "How You Sign Into Google"
Now you see the option for 2-step verication
Part of your 2-step verication will be a phone call or text message from google
Now you will enter the code from Google
Now you will be asked to sign into your email account again
Once two-step authentication is enabled, go back to the security page
In the Google Account Search Box type the following:
"Where are the app passwords"
before you finish typing a menu should appear
You will be asked to log in again
App passwords lets you sign into your Google Account from apps
on devices that don't support 2-step Verification. You'll only
need to enter it once so you don't need to remember it'
Now you can click the "Create" button
Copy and paste this password in the SMTP settings listed
in the "Edit User Settings" form under "Admin" on your main
menu in your program.
Next Step
Google will allow you to send 100 emails per day for free.
If for some reason you need more then 100 you can sign up for
their "G" service and pay them a monthly fee.
