How to Create a WordPress Child Theme

  • Navigate to the themes directory of your WordPress website and create a new child theme sub-folder in the path of your themes folder (for example, yourwebsitedomain/wp-content/themes/ChildTwentyFourteen/).  This sub-folder is going to be your new child theme folder for your current themes.  Mane the sub-folder something like “ChildTwentyFourteen” or be a little more creative than me.
  • Search Google for — child theme wordpress codex — and the first link that you should find and follow is to http://codex.wordpress.org/Child_Themes
  • On the codex support page which will be displayed from your search, please locate and copy the gray block of code to your clipboard memory.  Make sure you copy every line including the /* — */ comment part.  The code you copy should look like this:

/*
Theme Name: Twenty Fourteen Child
Theme URI: http://example.com/twenty-fourteen-child/
Description: Twenty Fourteen Child Theme
Author: John Doe
Author URI: http://example.com
Template: twentyfourteen
Version: 1.0.0
Tags: light, dark, two-columns, right-sidebar, responsive-layout, accessibility-ready
Text Domain: twenty-fourteen-child
*/

@import url(“../twentyfourteen/style.css”);

/* =Theme customization starts here
————————————————————– */

  •  Open your child theme folder and create a new text file called style.css.  Open the style.css file with your php editor, like notepad++ and paste into that file the code contents that you just copied to your clipboard (that is, paste the above code to the style.css file) and save the file contents of style.css.
  • You can modify each of the lines in the style.css file.  The required lines are the theme name, the Template, and the @import url line
  • Theme customization begins below the dashed line — like css changes.
  • Note: The child theme’s stylesheet is included after the parent theme’s and, consequently, the child theme styles will override those in the parent theme’s stylesheet.
  • Activate your childtheme in your wordpress administrative panels — Appearance — Themes.

You can override main content theme with your child theme content as follows.  For example, to remove or change the contents of the wordpress footer “Proudly Powered by WordPress,” you would first make a copy of footer.php (copied from the main theme folder and pasted into your child theme folder).  Open your child theme copy of the footer.php file using Notepad++ editor and edit the code.  Save the modified footer.php file.  Refresh your wordpress site and check your changes.

How to disable authenticated SMTP in MS Exchange 2003

SEE: http://support.zen.co.uk/kb/Knowledgebase/How-to-disable-authenticated-SMTP-in-MS-Exchange-2003?Keywords=server where this Article is Originally Published. Full credit for original authorship of this knowledge base Article goes to whoever published it at that URL. All copyrights remain with the original author. This article will be immediately removed from here on notice from support.zen.co.uk.

Aim of this article:

This article provides instructions on disabling authenticated delivery of e-mail over the SMTP protocol to a Microsoft Exchange 2003 Server, in order to prevent yourserver from being used as a relay for fraudulent e-mail.

Background

Out of the box MS Exchange 2003 is not an open relay, but it can be used as a relay if the spammer has usernames and passwords for users on your network. This authenticated relay is the most common way that spammers get MS Exchange to send their junk.
In an ideal world this would not be a problem because users would have complex passwords that cannot be guessed by using brute force, continuously attempting log in using possible passwords until a valid one is found. However, users will use as easy to remember a password as they can, thus making brute force password guessing very effective.
By disabling authentication when not on the office network, even if a network password is known, spam cannot be sent through the Exchange server, although other services exposed to the Internet may be exploited – remote desktop etc.
Note: most smartphones do not use SMTP for sending and receiving e-mail so disabling aSMTP in this way should not affect remote employees that use their phones to access e-mail.

Accessing Virtual SMTP server Properties

On the Exchange server, open Server Management, then in the left hand trees view expand the following:
Advanced Management > Domainname (Exchange) > Servers > ServerName > Protocols > SMTP
Right click and select properties of the Default SMTP Virtual Server

props

Select Access from the tabs at the top, and then click the button named Relay

relay rest

The Relay Restrictions window should open. By default under the Add button, a checkbox will be ticked. This “Allow all computers…..” checkbox is what allows someone with a valid password to send mail through your server from anywhere on the Internet. Un-tick this box.
Next click the button named Users…

Users

Ensure Authenticated Users only have Submit Permission ticked.
Selecting Relay Permission here will override removing the tick from the previous window.
To finish, click OK until all the properties boxes are closed.

MY COMMENTARY:

I am not sure whether it is necessary or advisable to grant relay access to the localhost at 127.0.0.1 nor the local IP bind to the network interface of the 2k3 exchange server. In other words, if your exchange server is located at 192.168.2.2, for example, it might not be wise to grant that either. It is, however, important to grant access to the exchange smtp relay from any perimeter smart host that you may use to forward email to your exchange server on your LAN.

FURTHER COMMENTARY IF YOU USE A SMART HOST OUTSIDE THE EXCHANGE LAN PERIMETER:

The smart host might have several separate email boxes:

user1 @ myDomain.com
smart host configured to keep a copy of each msg received, and redirect each message to user1 @ ExchangeServer.MyDomain.com

On the other hand, you may merely set the smart host to receive all mail for MyDomain.com) and forward it to ExchangeServer.MyDomain.com where the exchange server will sort the mail by account and deliver it to the appropriate mail box accounts.

Configure the MX records of both the perimeter smart host and the exchange server with the appropriate priorities.  The following, for example, will ensure that attempted delivery will be made first to the smart host (standard priority 10) and, if the smart host is offline, then secondary delivery will be made directly to the exchange server (priority 12).

smtp.smarthost.somedomain.com.  MX 10
smtp.exchangeserver.MyDomain.com MX 12

Q — Will shutting off relay to anyone other than the smart host and the local.lan prevent reception of internet mail destined for delivery (secondary priority) on the local 2k3 exchange server?
