# 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.

2014-03-30 21:39:27 -04:00
* Rewrites HTML enabling display of embedded, inline images/etc and open links in a new window.
2010-10-24 21:23:40 -04:00
* 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.

2011-05-31 13:38:19 -04:00
* Runs as a daemon run in the background.
* Sendmail-analogue command, `catchmail`, makes [using mailcatcher from PHP][withphp] a lot easier.

2012-04-19 11:26:40 -04:00
* Keyboard navigation between messages

## How
2010-10-24 21:23:40 -04:00
1. `gem install mailcatcher`
2. `mailcatcher`
3. Go to http://localhost:1080/
4. Send mail through smtp://localhost:1025
Use `mailcatcher --help` to see the command line options. The brave can get the source from [the GitHub repository][mailcatcher-github].

### Bundler
Please don't put mailcatcher into your Gemfile. It will conflict with your applications gems at some point.
Instead, pop a note in your README stating you use mailcatcher. Simply run `gem install mailcatcher` then `mailcatcher` to get started.
### RVM
2012-01-16 15:02:19 -05:00
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 and create wrapper scripts:
2013-02-25 02:10:16 -05:00
rvm default@mailcatcher --create do gem install mailcatcher
rvm wrapper default@mailcatcher --no-prefix mailcatcher catchmail
### Rails
2014-05-03 17:26:41 -04:00
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 => "localhost", :port => 1025 }
### PHP
For projects using PHP, or PHP frameworks and application platforms like Drupal, you can set [PHP's mail configuration](http://www.php.net/manual/en/mail.configuration.php) in your [php.ini](http://www.php.net/manual/en/configuration.file.php) to send via MailCatcher with:
sendmail_path = /usr/bin/env catchmail -f some@from.address
You can do this in your [Apache configuration](http://php.net/manual/en/configuration.changes.php) 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`.
2013-12-11 18:31:23 -05:00
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
2013-05-30 23:37:08 -04:00
### Django
For use in Django, simply add the following configuration to your projects' settings.py
```python
if DEBUG:
EMAIL_HOST = '127.0.0.1'
EMAIL_HOST_USER = ''
EMAIL_HOST_PASSWORD = ''
EMAIL_PORT = 1025
EMAIL_USE_TLS = False
2013-05-30 23:37:08 -04:00
```
### 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/:cid` for individual attachments by CID, or the whole message with `/messages/:id.source`.
## Caveats
2011-07-07 04:11:17 -04:00
* Mail processing is fairly basic but easily modified. If something doesn't work for you, fork and fix it or [file an issue][mailcatcher-issues] and let me know. Include the whole message you're having problems with.
* The interface is very basic and has not been tested on many browsers yet.
2010-10-24 21:23:40 -04:00
## TODO
* Add mail delivery on request, optionally multiple times.
2011-06-09 23:22:19 -04:00
* An API-compatible nodejs version, for fun and profit (and non-ruby npm users).
2011-06-09 23:24:08 -04:00
* Test suite.
2014-06-02 13:32:40 -04:00
* Compatibility testing against CampaignMonitor's [design guidelines](http://www.campaignmonitor.com/design-guidelines/) and [CSS support matrix](http://www.campaignmonitor.com/css/).
2010-10-24 21:23:40 -04:00
* Forward mail to rendering service, maybe CampaignMonitor?
2010-10-27 15:23:29 -04:00
* Package as an app? Native interfaces? HotCocoa?

## Thanks
2010-10-24 21:23:40 -04:00
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.
Thanks also to [The Frontier Group][tfg] for giving me the idea, being great guinea pigs and letting me steal pieces of time to keep the project alive.
