A simple local SMTP server [closed]

问题:

I want to test a Java code for sending email. I don't want to use any commercial mail client or connect to any external mail providers (like Gmail or Yahoo). I would like to know if there is any software which allows a user to configure dummy email addresses and server (locally) which can be used in my software to send and receive mails. I just want to test the functionality of the Java code.

For email testing, try Dumbster. From that page:

The Dumbster is a very simple fake SMTP server designed for unit and system testing applications that send email messages. It responds to all standard SMTP commands but does not deliver messages to the user. The messages are stored within the Dumbster for later extraction and verification.

The Dumbster slots itself very easily into your testing strategy. As long as your application talks to an email server using SMTP then the Dumbster can be used to test the application with no code changes.

I prefer Fake SMTP for this. It's a desktop app (packed into jar file). Since it is written in Java, you can run it both from Linux/Mac/Windows

回答3:

Try GreenMail. It's geared towards JUnit usage, but it should do what you need. You can run it in a JBoss instance or have your JUnit tests send mail to themselves, depending on your specific needs.

There are a few other similar bits of software out there, but that's the one I've used and was reasonably happy with it.

You can use Wiser in the SubEthaSMTP library, Wiser's purpose is exactly what you want, unit testing.

on Leopard you can start a Local SMTP Server (Postfix) on OS-X Leopard

sudo vi /System/Library/LaunchDaemons/org.postfix.master.plist

before the closing tag at the end:

<key>RunAtLoad</key> <true/> <key>KeepAlive</key> <true/>

then start the thing with

sudo postfix start

now you check wheter the service is running with:

telnet localhost 25

The javamail-file-transport saves emails to files instead of sending them through SMTP server.

See the javaMail extensions project on GitHub.

It adds file transport that allows:

• save mails to files in text format instead of sending them
• save mails to files in mbox format instead of sending them
• add log info instead of sending email

I've used Mailtrap a few times, and I can recommend it.

use the Aspirin From the docs: Aspirin is an embeddable send-only SMTP server for Java developers.

amazing docker
https://hub.docker.com/r/mailhog/mailhog/
(gitHub - https://github.com/mailhog/MailHog)
This docker has two ports:
One port for sending SMTP e-mails (smtp://0.0.0.0:1025/)
A second port to the e-mail display on the web (http://0.0.0.0:8025/)

run docker:
docker pull mailhog/mailhog
docker run --name=mailhog -d -p 1025:1025 -p 8025:8025 mailhog/mailhog
