| <a name="Postage - A Mail-Traffic Generator"></a><div class="section"><h2>Postage - A Mail-Traffic Generator</h2> |
| <p>Postage is a stand-alone pure-java application generating mail traffic on mail servers.</p> |
| <p>It uses standard mail protocols to do this, currently POP3 and SMTP.</p> |
| <p>Therefore, it is well suited for testing any mail server supporting those protocols.</p> |
| <p>It was particularily created for running against Apache James Server and contains special feature for it.</p> |
| </div> |
| |
| <a name="Load scenarios"></a><div class="section"><h2>Load scenarios</h2> |
| <p>Through the easy-to-use XML-file-based configuration, you can specify exactly the running scenario for your load profile.</p> |
| <p>Supports unlimited number of internal and external users.</p> |
| <p>Is flexible enough to mimic many real-world load scenarios, for example |
| <ul> |
| <li>many users, each receiving few mails every day</li> |
| <li>few users, heavily receiving mails</li> |
| <li>moderate mail traffic, yet very big attachments</li> |
| </ul> |
| |
| Within one scenario, Postage supports different email profiles running in parallel. Every profile has its own specification in terms of |
| <ul> |
| <li>number of generated mails per minute</li> |
| <li>sender/receiver</li> |
| <li>mail size</li> |
| </ul> |
| |
| </div> |
| |
| <a name="Delivery analysis"></a><div class="section"><h2>Delivery analysis</h2> |
| Going beyond tools like <i>postal</i>, Postage tries to capture its test mails on the target location, records statistics and validates the result. |
| So you can see not only the load, but also track successful and failed deliveries. |
| </div> |
| |
| <a name="Track Server resource consumption"></a><div class="section"><h2>Track Server resource consumption</h2> |
| Postage is able to monitor the Server for memory and thread consumption, if it is running under Java 5 SE. |
| </div> |
| |
| <a name="Pluggability"></a><div class="section"><h2>Pluggability</h2> |
| Per default, Postage generates test mails containing one textual and one binary part each having random sizes. |
| This default behavior can be overridden on a email profile basis. User defined MailFactory and MailValidator classes which generate and handle use-case-specific mails can be plugged in very easily. |
