    MailCatcher

    MailCatcher

    Catches mail and serves it through a dream

    Catches mail and serves it through a dream. MailCatcher runs a super simple SMTP server that catches any message sent to it to display in a web interface. Run mailcatcher, set your favorite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check it out to see the mail that's arrived so far. Shows HTML, Plain Text and Source version of messages, as applicable. Rewrites HTML enabling display of embedded, inline images/etc and opens links in a new window. Command-line options to override the default SMTP/HTTP IP and port settings. Mail appears instantly if your browser supports WebSockets, otherwise updates every thirty seconds. Sendmail-analogue command, catchmail, makes using mailcatcher from PHP a lot easier. Encodings are difficult. MailCatcher does not completely support utf-8 straight over the wire, you must use a mail library that encodes things properly based on SMTP server capabilities.

    MailSlurper

    MailSlurper

    Local, web-based mail server application. Slurp mails into oblivion!

    MailSlurper is a small SMTP mail server that slurps mail into oblivion! MailSlurper is perfect for individual developers or small teams writing mail-enabled applications that wish to test email functionality without the risk or hassle of installing and configuring a full-blown email server. It's simple to use! Simply set up MailSlurper, configure your code and/or application server to send mail through the address where MailSlurper is running, and start sending emails! MailSlurper will capture those emails into a database for you to view at your leisure. The following are general instructions for compiling MailSlurper. Your details may vary a bit here and there. The below example is based on a Unix-style system, such as Ubuntu or OSX. Furthermore, for instructional purposes, it is assumed that your GOPATH is set to ~/code/go, and that you have a folder in your source directory called github.com. Your setup may vary.

    Nylas Mail

    Nylas Mail

    An extensible desktop mail app built on the modern web

    Nylas Mail is an open-source mail client built on the modern web with Electron, React, and Flux. It was designed to be easy to extend, and many third-party plugins are available that add functionality to the client. See /packages for the separate pieces. Each folder in /packages is designed to be its own stand-alone repository. They are all bundled here for the ease of source control management. In early 2016, the Nylas Mail team wrote extensive documentation for the app that was intended for plugin developers. This documentation lives on GitHub Pages and offers a great overview of the app's architecture and important classes. When you download and build Nylas Mail from the source it runs without its cloud components. The concept of a "Nylas ID" / subscription has been removed, and plugins that require server-side processing are disabled by default. (Plugins like Snooze, Send Later, etc.)

    Rspamd

    Rspamd

    Rapid spam filtering system

    Rspamd is an advanced spam filtering system and email processing framework that allows evaluation of messages by a number of rules including regular expressions, statistical analysis and custom services such as URL black lists. Each message is analysed by Rspamd and given a verdict that might be used by MTA for further processing (e.g. to reject a message, or add a special header indicating spam) along with other information, such as possible DKIM signature or modifications suggested for a message. Rspamd can act as a Milter allowing direct interaction with popular MTA systems, such as Postfix or Sendmail. Rspamd is designed to process hundreds of messages per second simultaneously, and provides a number of useful features including a comprehensive Lua API that allows access to messages processing in various aspects as well as asynchronous network API to access external resources, such as DNS, HTTP or even generic TCP/UDP services.

    SwiftMailer

    SwiftMailer

    Comprehensive mailing tools for PHP

    SwiftMailer is a flexible, object-oriented PHP library for sending emails via SMTP, Sendmail, or other transports (including third-party APIs). It supports features essential to robust email sending: attachments, HTML vs. plain text bodies, inline images, MIME types, message queues, and signed messages via DKIM. The API lets developers build richly composed messages with multiple parts, headers, and encodings without dealing with raw mail formatting. With built-in retry logic, logging, and error handling, it handles network failures gracefully, integrating into applications or frameworks for background dispatch. Though newer libraries such as Symfony Mailer have emerged, SwiftMailer remains influential in legacy codebases and continues to serve as a reference for well-structured email composition in PHP.

    VarDumper Component

    VarDumper Component

    Provides mechanisms for walking through any arbitrary PHP variable

    The VarDumper component provides mechanisms for walking through any arbitrary PHP variable. It provides a better dump() function that you can use instead of var_dump(). The VarDumper component creates a global dump() function that you can use instead of e.g. var_dump. By using it, you’ll gain per object and resource types specialized view to e.g. filter out Doctrine internals while dumping a single proxy entity, or get more insight on opened files with stream_get_meta_data. Configurable output formats, HTML or colored command line output. Ability to dump internal references, either soft ones (objects or resources) or hard ones (=& on arrays or objects properties). Repeated occurrences of the same object/array/resource won’t appear again and again anymore. Moreover, you’ll be able to inspect the reference structure of your data. Ability to operate in the context of an output buffering handler.

    peco

    peco

    Simplistic interactive filtering tool

    peco (pronounced peh-koh) is based on a python tool, percol. percol was darn useful, but I wanted a tool that was a single binary, and forget about python. peco is written in Go, and therefore you can just grab the binary releases and drop it in your $PATH. peco can be a great tool to filter stuff like logs, process stats, find files, because unlike grep, you can type as you think and look through the current results. Demos speak more than a thousand words! Here's me looking for a process on my mac. You can page through your results, and you can keep changing the query. When you combine tools like zsh, peco, and ghq, you can make managing/moving around your huge dev area a piece of cake! Search results are filtered as you type. When you find that line that you want, press enter, and the resulting line is printed to stdout, which allows you to pipe it to other tools. You can select multiple lines!
