| <p>Before you can send a message to one of the Apache Tomcat<sup>®</sup> lists, you must subscribe |
| to that list. If you try to send a message to a list from an e-mail address that |
| is not subscribed to the list, it will be rejected.</p> |
| |
| <p>All messages to the Tomcat lists are filtered for spam. To avoid your valid |
| message being marked as spam:</p> |
| <ul> |
| <li>send your message in plain text, not HTML;</li> |
| <li>include a subject.</li> |
| </ul> |
| |
| <p>The following lists are available:</p> |

| |
| <p>Users should consider subscribing to the |
| <a href="#tomcat-users">User Support</a> and the |
| <a href="#tomcat-announce">Announcements</a> mailing lists. |
| |
| The <a href="#tomcat-dev">Developer</a> list is for people interested in |
| helping with the development and debugging of the server.</p> |
| |
| <p>Formatted archives are available in several places including <a href="https://lists.apache.org/list.html?users@tomcat.apache.org">the Apache |
| Mail Archives</a>, and <a href="https://marc.info/" rel="nofollow">MARC</a>. The |

| <p>The list listed here is the <strong>only</strong> place that configuration |
| and how-to questions belong, ever. Every day, users become frustrated, not |
| with Apache Tomcat, but how nobody will help them understand how to get |
| started. 95% of the time, it's not for lack of helpers, but for lack of |
| effort and well stated questions.</p> |
| |
| <p>Before you go further, please read Eric S. Raymond and Rick Moen's |
| explanation of |
| <a href="http://www.catb.org/~esr/faqs/smart-questions.html" rel="nofollow"> |
| "How To Ask Questions The Smart Way"</a>. If you follow their advice, you |
| will discover that these forums have dozens of helpers ready to provide you |
| with guidance on using Apache Tomcat! <strong>Note: Do not send your Apache |
| Tomcat questions to Eric or Rick themselves!</strong></p> |
| |
| <p><strong>Important:</strong></p> |
| |
| <ol> |
| <li>You <strong>must</strong> be subscribed to the mailing list before you |
| post a question. If you do not subscribe first, your post will be |
| automatically rejected.</li> |
| <li>When asking questions on the list, please state your exact Tomcat version |
| (which is three numbers, 11.0.zz, 10.1.yy or 9.0.xx), your operating system, |
| and essential bits of your configuration. |
| </li> |
| <li>Note, that Tomcat Documentation is provided on this site and is searchable |
| (see links and search box at the left). Add "Tomcat 11.0", "Tomcat 10.1", |
| or "Tomcat 9.0" to your query to refine your results. The tomcat-users mailing |
| list archives (links are below) are also searchable.</li> |
| <li>The |
| <a href="https://cwiki.apache.org/confluence/display/TOMCAT/FAQ">FAQ</a> and |
| <a href="https://cwiki.apache.org/confluence/display/TOMCAT/HowTo">How To</a> |
| pages are available at the |
| <a href="https://cwiki.apache.org/confluence/display/TOMCAT">Tomcat |
| Wiki</a>.</li> |
| <li>Usage of these mailing lists is subject to the |
| <a href="https://www.apache.org/foundation/public-archives.html">Public Forum Archive Policy</a>.</li> |
| <li>To post a question, start a new thread by sending your mail |
| to the "Posting questions" address below. Do not reply to an existing e-mail.</li> |
| <li>When replying, please write your text below the quoted one. |
| <a href="https://en.wikipedia.org/wiki/Posting_style#Choosing_the_proper_posting_style" rel="nofollow">Top-posting</a> |
