 * Message and Spam Filter Plugin - Setup script

 * not the place of the client, which is why this has been made a plugin for
 * SquirrelMail.  You may be better off using products such as Sieve or
 * Procmail to do your filtering so it happens even when SquirrelMail isn't
 * running.
 *
 * If you need help with this, or see improvements that can be made, please
 * email me directly at the address above.  I definately welcome suggestions
 * and comments.  This plugin, as is the case with all SquirrelMail plugins,

 * mailing list if you have trouble with it.
 *
 * Also view plugins/README.plugins for more information.

   //
   // or:
   //
   // https://www.onedomain.com/mail/src/login.php?domain=virtualdomain.com
   //
   // set this value to the pattern that will reproduce the correct
   // SSL URI to the Squirrelmail login page.  Substitutions you can use:
   //
   // ###DOMAIN###  --  The full domain from the original http request,
   //                   such as virtualdomain.com
   // ###PATH###    --  The pah/directory information from the original
   //                   http request, such as /mail or /mail/src/login.php
   // ###QUERY###   --  The query string from the original http request,
   //                   such as ?mynameis=pavel&color=green
   // 
   // The two examples below construct URI patterns just like
   // the URIs given above.

   // NOTE that this setting can also be useful in scenarios where you 
   // need fine-grained control over the encrypted URI, even when the 
   // URI is different for any virtual hosts you may have.  For example:
   //
   // $allVirtualDomainsUnderOneSSLHost = 'https://secret.###DOMAIN###/secret_mail/src/login.php###QUERY###';
   //
   $allVirtualDomainsUnderOneSSLHost = '';



   // the above $allVirtualDomainsUnderOneSSLHost setting assumes that the
   // original plain (unencrypted) http request comes from a URI such as:
   // 
   // http://virutaldomain.com/mail/src/login.php
   //
   // however, if your entry point will also be in a similar format, such as:

   //
   // or:
   //
   // http://www.onedomain.com/mail/src/login.php?domain=virtualdomain.com
   //
   // set these values each to a regular expression that will capture:
   //
   //   the domain portion of the URI in the first group (set of parenthesis)
   //   the path portion of the URI in the first group (set of parenthesis)
   //   the query portion of the URI in the first group (set of parenthesis)
   // 
   // otherwise, leave these all set to empty strings.
   //
   // The two examples below pick the domain, path and query string out of 
   // the sample URIs given above.
   //
   // $entryPointDomainPattern = '/[\/]+.+?\/(.+?)(\/|$)/';
   // $entryPointPathPattern   = '/[\/]+.+?\/.+?(\/.*?)(\?|$)/';

   // $entryPointPathPattern   = '/[\/]+.+?(\/.*?)(\?|$)/';
   // $entryPointQueryPattern  = '/(\&.*)/';
   //
   // NOTE that these settings can also be useful in scenarios where you
   // need better control over the domain parsing of the original entry
   // URI.  This should only be used if the auto-sensing behavior of the
   // plugin will not work.  For example:
   //
   $entryPointDomainPattern = '';
   $entryPointPathPattern   = '';
   $entryPointQueryPattern  = '';



   // by default, https requests are made without explicitly defining the
   // port number.  if you use a non-standard port for serving http requests, 
   // that port will be preserved for the https redirection, which may break
   // your squirrelmail.
   // 
   // if your server listens for https requests on a non-standard port or
   // the above situation applies to you (non-standard http port), you can 
   // specify a non-standard https port number here (or remove it, forcing 
   // the browser use the default port (443)).
   // 
   // if you use this setting, remember to remove the slashes in front of it
   //
   // $sl_securePort = '';
   // $sl_securePort = '888';
   $sl_securePort = '443';



   // if you are running regular HTTP requests on a non-standard port
   // (anything besides port 80), please specify that value here
   // if you are using port 80, then you should leave this value empty
   //
   //$nonStandardHttpPort = '80';
   $nonStandardHttpPort = '';



   // If you run SquirrelMail behind a proxy server, where the
   // client domain information is in X_FORWARDED_* headers,
   // enable this setting (set it to 1), otherwise, leave this
   // off (zero) to reduce the chance that someone can try to
   // forge the hostname in their request headers.
   //
   // $sl_obey_x_forwarded_headers = 1;
