well, you have to edit XOOPS_ROOT_PATH/include/site-closed.php
Line 42 aprox.
$xoopsTpl->assign( array(
'xoops_theme' => $xoopsConfig['theme_set'],
'xoops_imageurl' => XOOPS_THEME_URL.'/'.$xoopsConfig['theme_set'].'/',
'xoops_themecss'=> xoops_getcss($xoopsConfig['theme_set']),
'xoops_requesturi' => htmlspecialchars( $_SERVER['REQUEST_URI'], ENT_QUOTES),
'xoops_sitename' => htmlspecialchars($xoopsConfig['sitename'], ENT_QUOTES),
'xoops_slogan' => htmlspecialchars($xoopsConfig['slogan'], ENT_QUOTES),
'xoops_dirname' => @$xoopsModule ? $xoopsModule->getVar( 'dirname' ) : 'system',
'xoops_banner' => $xoopsConfig['banners'] ? xoops_getbanner() : ' ',
'xoops_pagetitle' => isset($xoopsModule) && is_object($xoopsModule) ? $xoopsModule->getVar('name') : htmlspecialchars( $xoopsConfig['slogan'], ENT_QUOTES ),
'lang_login' => _LOGIN,
'lang_username' => _USERNAME,
'lang_password' => _PASSWORD,
'lang_siteclosemsg' => $xoopsConfig['closesite_text'],
) );
change by
$xoopsTpl->assign( array(
'xoops_theme' => $xoopsConfig['theme_set'],
'xoops_imageurl' => XOOPS_THEME_URL.'/'.$xoopsConfig['theme_set'].'/',
'xoops_themecss'=> xoops_getcss($xoopsConfig['theme_set']),
'xoops_requesturi' => htmlspecialchars( $_SERVER['REQUEST_URI'], ENT_QUOTES),
'xoops_sitename' => htmlspecialchars($xoopsConfig['sitename'], ENT_QUOTES),
'xoops_slogan' => htmlspecialchars($xoopsConfig['slogan'], ENT_QUOTES),
'xoops_dirname' => @$xoopsModule ? $xoopsModule->getVar( 'dirname' ) : 'system',
'xoops_banner' => $xoopsConfig['banners'] ? xoops_getbanner() : ' ',
'xoops_pagetitle' => isset($xoopsModule) && is_object($xoopsModule) ? $xoopsModule->getVar('name') : htmlspecialchars( $xoopsConfig['slogan'], ENT_QUOTES ),
'lang_login' => _LOGIN,
'lang_username' => _USERNAME,
'lang_password' => _PASSWORD,
'lang_siteclosemsg' => $xoopsConfig['closesite_text'],
'xoops_adminmail' => $xoopsConfig['adminmail'],
) );
As you can see, add
'xoops_adminmail' => $xoopsConfig['adminmail'],so You can use
<{$adminmail}> in system_siteclosed.html
