MailCatcher: Catches Mail and Serves It Through A Dream on Ruby

MailCatcher

Catches mail and serves it through a dream.

MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface. Run mailcatcher, set your favourite app to deliver to smtp://127.0.0.1:1025 instead of your default SMTP server, then check out http://127.0.0.1:1080 to see the mail that's arrived so far.

Features

• Catches all mail and stores it for display.
• 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.
• Lists attachments and allows separate downloading of parts.
• Download original email to view in your native mail client(s).
• 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.
• Runs as a daemon in the background, optionally in foreground.
• Sendmail-analogue command, catchmail, makes using mailcatcher from PHP a lot easier.
• Keyboard navigation between messages

How

1. gem install mailcatcher
2. mailcatcher
3. Go to http://127.0.0.1:1080/
4. Send mail through smtp://127.0.0.1:1025

Command Line Options

Use mailcatcher --help to see the command line options.

Usage: mailcatcher [options]

MailCatcher v0.8.0

        --ip IP                      Set the ip address of both servers
        --smtp-ip IP                 Set the ip address of the smtp server
        --smtp-port PORT             Set the port of the smtp server
        --http-ip IP                 Set the ip address of the http server
        --http-port PORT             Set the port address of the http server
        --messages-limit COUNT       Only keep up to COUNT most recent messages
        --http-path PATH             Add a prefix to all HTTP paths
        --no-quit                    Don't allow quitting the process
    -f, --foreground                 Run in the foreground
    -b, --browse                     Open web browser
    -v, --verbose                    Be more verbose
    -h, --help                       Display this help information
        --version                    Display the current version

Upgrading

Upgrading works the same as installation:

gem install mailcatcher

Ruby

If you have trouble with the setup commands, make sure you have Ruby installed:

ruby -v
gem environment

You might need to install build tools for some of the gem dependencies. On Debian or Ubuntu, apt install build-essential. On macOS, xcode-select --install.

If you encounter issues installing thin, try:

gem install thin -v 1.5.1 -- --with-cflags="-Wno-error=implicit-function-declaration"

Bundler

Please don't put mailcatcher into your Gemfile. It will conflict with your application's gems at some point.

Instead, pop a note in your README stating you use mailcatcher, and to run gem install mailcatcher then mailcatcher to get started.

RVM

Under RVM your mailcatcher command may only be available under the ruby you install mailcatcher into. To prevent this, and to prevent gem conflicts, install mailcatcher into a dedicated gemset with a wrapper script:

rvm default@mailcatcher --create do gem install mailcatcher
ln -s "$(rvm default@mailcatcher do rvm wrapper show mailcatcher)" "$rvm_bin_path/"

Rails

To set up your rails app, I recommend adding this to your environments/development.rb:

config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = { :address => '127.0.0.1', :port => 1025 }
config.action_mailer.raise_delivery_errors = false

PHP

For projects using PHP, or PHP frameworks and application platforms like Drupal, you can set PHP's mail configuration in your php.ini to send via MailCatcher with:

sendmail_path = /usr/bin/env catchmail -f some@from.address

You can do this in your Apache configuration like so:

php_admin_value sendmail_path "/usr/bin/env catchmail -f some@from.address"

If you've installed via RVM this probably won't work unless you've manually added your RVM bin paths to your system environment's PATH. In that case, run which catchmail and put that path into the sendmail_path directive above instead of /usr/bin/env catchmail.

If starting mailcatcher on alternative SMTP IP and/or port with parameters like --smtp-ip 192.168.0.1 --smtp-port 10025, add the same parameters to your catchmail command:

sendmail_path = /usr/bin/env catchmail --smtp-ip 192.160.0.1 --smtp-port 10025 -f some@from.address

Django

For use in Django, add the following configuration to your projects' settings.py

if DEBUG:
    EMAIL_HOST = '127.0.0.1'
    EMAIL_HOST_USER = ''
    EMAIL_HOST_PASSWORD = ''
    EMAIL_PORT = 1025
    EMAIL_USE_TLS = False

API

A fairly RESTful URL schema means you can download a list of messages in JSON from /messages, each message's metadata with /messages/:id.json, and then the pertinent parts with /messages/:id.html and /messages/:id.plain for the default HTML and plain text version, /messages/:id/parts/:cid for individual attachments by CID, or the whole message with /messages/:id.source.

Caveats

• Mail processing is fairly basic but easily modified. If something doesn't work for you, fork and fix it or file an issue and let me know. Include the whole message you're having problems with.
• Encodings are difficult. MailCatcher does not completely support utf-8 straight over the wire, you must use a mail library which encodes things properly based on SMTP server capabilities.

Thanks

MailCatcher is just a mishmash of other people's hard work. Thank you so much to the people who have built the wonderful guts on which this project relies.

Donations

I work on MailCatcher mostly in my own spare time. If you've found Mailcatcher useful and would like to help feed me and fund continued development and new features, please donate via PayPal. If you'd like a specific feature added to MailCatcher and are willing to pay for it, please email me.

Aside from that, they can likewise reclassify components by eliminating or adding them during the development environment. Indeed, even individual projects can be extended and changed. 

Convention over configuration

Regardless of whether it's Ruby on Rails enterprise application development or ecommerce-centered applications, the system utilizes convention over configuration. Developers don't have to go through hours attempting to set up the Ruby on Rails improvement environment. The standard conventions cover everything, improving on things for engineers on the task.

Why should we use Ruby on Rails for Software Development?

What is Rails, Ruby on Rails?

Rails is a server-side web application development framework written in the Ruby programming language. Its emergence in 2005 has influenced and impacted web application development to a vast range, including but not limited to seamless database tables, migrations, and scaffolding of views. In the simplest understanding, Rails is a highly productive and intuitive software developer. 

Websites and applications of any complexity can be achieved with Ruby on Rails. The software is designed to perceive the needs of ruby on rails developers and encourage them with the best way out. It is designed to allow developers to write lesser code while spiking productivity much more than any other framework or language. Ruby on Rails rapid application development offers everyday web development tasks easier and uniquely out-of-the-box, both with the same effectiveness.

The Ruby on Rails framework is based on two philosophies:

 

• Don’t Repeat Yourself (DRY): It is a software development principle that ensures that every piece or entity of knowledge must be assigned with a single and unambiguous representation within a development system.
  
  It not only reduces the need to write lengthy codes but also eliminates the repetitive writing of codes. As a result, it provides a much more manageable web app development with the least possible bugs.
  

 

• Convention over Configuration (CoC): It indicates the highly opinionated feature that the Ruby on Rails framework possesses. It offers ready-made solutions or the “best way out” for many tasks in a web application and defaults them to the convention without the need for external specification. The programmer using the software is required to specify only the unconventional aspects of the web application. 

Some of the commonly known websites built by the Ruby on Rails software developers are Instacart, Scribd, Shopify, Github, ConvertKit, Soundcloud, GoodReads, Airbnb. It finds its application in Sa-as Solutions, Social Networking Platforms, Dating websites, Stock Exchange Platforms, etc.

Why use Ruby on Rails: The multifold benefits

• Community and its abundant resources 

• There is a large community that is dedicated to Ruby on Rails that keeps it up-to-date and indeed encourages its family of developers to continue using it. They make sure the benefits are soaring with every update they make. 

• The community is committed to developing several ready-to-use code packages, commonly known as gems, for its users. They discuss and announce new project launches, help each other with queries, and engage in framework discussions and betterment. While Ruby on Rails helps developers in rapid application development, it also connects and grows businesses together.

• Project Scalability

• To talk about scalability, we indicate the ability to grow and manage more and more user requests per minute (RPM). However, this depends on the architecture rather than the framework. The right architecture of Ruby on Rails web application development allows it to write bulky codes and programs as compared to early-stage difficulties with scalability. 

• It uses the Representational State Transfer (REST) architecture. This will enable Rails to create efficient web applications based on Rails 6, launched last year in 2020, which addresses most scalability issues. The portable components are agile and help in a better understanding of new requirements and needful adaptations for any business. The framework and architecture allow both vertical and horizontal scalability.
  

• Fast Application Development and Cost Effectiveness

• Ruby on Rails is lucid, logical, and has lean code requirements, thereby cutting down redundancy and improving the overall development speed. Lesser amount of code is proportional to lesser time investment with optimal results. The more time it takes for development, the more expensive it becomes for the end customers.

• Considering the ready-made code modules/packages (gems) available, Ruby on Rails development company will less time and money are spent creating and modifying Rails websites and applications. Another advantage that has made Ruby on Rails super attractive for startups is its use of Model-View-Controller (MVC) architecture. It has a component separation scheme that speeds up the web development process and fixes any errors that occur.  

• Data Protection

• Rails framework and the Ruby on Rails community put in a lot of efforts for data protection and security of its customer base. It is also one of the efficient frameworks for developing database-backed applications. 

• The developers at Ruby on Rails cover many aspects of cybersecurity, including encryptions of  passwords, credit card information, and users’ personal database. Special measures are taken to prevent the framework from SQL injections and XSS attacks. 

• Ruby on Rails Enterprise Application Development

• Ruby on Rails simplifies the daily operations and lowers the cost of enterprise app developments. The prominent features include data management, seamless updating of applications, easy and efficient code development, and high scalability, as discussed above. 

• Ruby on Rails enterprise application development is preferred by companies and is slightly cost-intensive. It can be easily integrated with third-party apps like Oracle Business, Oracle, Windows services, and others. Ruby enterprise app development allows the developers and programmers to solve the problems at the root level, given its transparency.

Bottom Line

There are several reasons to prefer Ruby on Rails discussed above and extend further to early detection of errors, reduced time to market, and easy adaptation for API developments. It makes web programming much easier and simplifies website building of any complexity. Its flexibility and acceptance among new developers and programmers make it the perfect, one-stop choice for software application development company in 2021.
