Hi All, When I add a dtml-sendmail block to my standard_error_message, I no longer get the custom error page at all, but the built-in one (headed up "Site Error." I read in the archives that this can be due to the standard_error_message object itself raising an error, but I have put the code in another object and it works fine there. Any idea what I've done wrong? Any help would be greatly appreciated. The code in question is included below. Thanks a lot, Arian Here's the code for the standard_error_message object I'm using, which tests for a NotFound error to treat 404 errors differently. If the sendmail block is removed, it works fine. The mailhost object *does* exist -- the sendmail block works perfectly when used elsewhere. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html40/strict.dtd"> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <title> <dtml-if "error_type=='NotFound'"> Page Not Found - NIWA <dtml-else> Website Error - NIWA </dtml-if> </title> <dtml-var style> </head> <body class="paddedminimal"> <img id="mainlogo" src="/niwalogo300.jpg" alt="NIWA" width="300" height="51"> <dtml-if "error_type=='NotFound'"> <h1>Page Not Found</h1> <p>Sorry – the page requested couldn’t be found.</p> <dtml-sendmail mailhost="mailhost"> To: a.dewit@niwa.co.nz From: web@niwa.co.nz Subject: 404 Error URL: <dtml-var SERVER_URL><dtml-var PATH_INFO><dtml-if QUERY_STRING>?<dtml-var QUERY_STRING></dtml-if> Referrer: <dtml-var HTTP_REFERER> </dtml-sendmail> URL: <dtml-var SERVER_URL><dtml-var PATH_INFO><dtml-if QUERY_STRING>?<dtml-var QUERY_STRING></dtml-if> Referrer: <dtml-var HTTP_REFERER> <dtml-else> <h1>Website Error</h1> <p>Zope has encountered an error while publishing this resource.</p> <p> <strong>Error Type: <dtml-var error_type></strong><br> <strong>Error Value: <dtml-var error_value></strong><br> </p> <hr> <p>Troubleshooting Suggestions</p> <ul> <li>The URL may be incorrect.
