Can mail go to web app and gmail

Yes, it is possible to send mail to a web app and Gmail using various programming languages and APIs. Here are some examples:

Sending mail to a web app:

1. HTTP POST request: You can send a POST request to a web app's API endpoint with the email content as a JSON payload. The web app can then process the email and store it in a database or send it to a mail server.
2. SMTP: You can use an SMTP library to send an email to a web app's mail server. The web app can then receive the email and process it accordingly.

Sending mail to Gmail:

1. Gmail API: You can use the Gmail API to send emails to Gmail users. You'll need to create a project in the Google Cloud Console, enable the Gmail API, and obtain credentials to use the API.
2. SMTP: You can use an SMTP library to send an email to a Gmail account. You'll need to use the Gmail SMTP server (smtp.gmail.com) and authenticate using your Gmail credentials.
3. Gmail's SMTP relay: You can use Gmail's SMTP relay service to send emails to Gmail users. This service allows you to send emails to Gmail users without having to authenticate with the Gmail SMTP server.
