local smtp server to send mail [closed]

Answer 1

You can also (for a demo) user the 'specifiedPickupDirectory' setting to leverage the same code, but drop the email message off to a local folder, alleviating the need for an actual SMTP server, but being able to demonstrate that the email is generated as expected.

Answer 2

Papercut is pretty active (last release on Jun 25, 2015):

Ever need to test emails from an application or web site but don't want them accidently being sent or having to deal with the hassle of setting up a test email server? Papercut is a quick email viewer with a built-in SMTP server designed to only receive messages. It doesn't enforce any restrictions how you send your email. It allows you to view the whole email-chilada: body, html, headers, attachment down to the naughty raw bits. It can be set to run on startup and sits quietly minimized in the tray giving you a balloon popup when a new message arrives.

You can also try smtp4dev:

A dummy SMTP server for Windows, Linux, Mac OS-X (and maybe elsewhere where .NET Core is available)

Answer 3

Local smtp only: smtp4dev (similar to papercut)
The application catches everything sent to it, but does not send emails over the internet.

Answer 4

You can send email using Telnet or implement the protocol using socket programming.

Answer 5

XMail or hMailServer should do the trick.

Answer 6

As for me the best option is https://www.npmjs.com/package/maildev

A painless smtp server running on node. Therefore you need to install node, but it actually send an email to any smtp server.
