Setting The Correct Sender Address In Postfix

My mac (work computer) is set up with usernames in the format of first inital, last name (lblue). We use Rackspace Email for our company email and our email addresses are set up as just FirstName@domain.com (Lee@domain.com). So, the problem with the default Postfix configuration is that it attempts to send mail based on the username on my mac. So when postfix attempts to send mail from lblue@domain.com our Rackspace Email server complains with a “Sender address rejected” error message. Fortunately, the solution is pretty easy.

Step 1: Edit your /etc/postfix/main.cf and add following line to your configuration.

sender_canonical_maps = hash:/etc/postfix/sender_canonical

Step 2: Create the sender canonical file /etc/postfix/sender_canonical and set up the username / email address associations

lblue    Lee@domain.com

Step 3: Run postmap on your new sender canonical file

sudo postmap /etc/postfix/sender_canonical

Step 4: Reload Postfix

sudo postfix reload

1. Visit the page in your web browser
2. View the source code for the page
3. Search the source code for src

Click through all the instances of src and look for items that are sourced through http:// rather than https://. Look at all your images, javascripts, stylesheets, etc. They all need to be pulled through https:// in order for your page to be totally secure and for that warning to go away. Internet Explorer is particularly finicky about this message so be sure to check your site in IE to make sure you don’t get this message: ‘This Page Contains Both Secure and Non-Secure Items‘ The FireFox message that means the same thing is ‘Warning: Contains Unauthenticated Content‘ this is the same problem. Just make sure your page is pulling all it’s resources through https:// and that is how you fix the error about ’secure and non-secure’ items on your SSL pages.

5. WP Super Cache

If you have a popular WordPress website you should seriously consider running WordPress Super Cache to improve the performance of your website. If you are not caching your pages, then every time a visitor comes to your site, WordPress has to pull together various pieces of information out of a database to put your page together. If you have a high traffic site, this is can really become a problem. WP Super Cache will store a copy of each of the pages on your website so that after the page has been assembled from the database once, WordPress can rest and just keep serving the static html copy of the page. This might be a bit techy, but the idea is you can dramatically speed up your site and reduce the load on your server by using WP Super Cache. If for no other reason, use this plugin so you don’t have to panic when your friend says, “I just Dugg your site.”

SELECT count(*) FROM myTableName WHERE someColumn='someValue';

But when you are using a Zend_Db_Table it’s a little confusing how to get the “count(*)” part to work because Zend_Db_Table likes to throw errors saying that it can’t be joined with other tables. So, in your Zend_Db_Table class, here is the syntax you can use:

$sql = $this->select()
       ->from($this, 'COUNT(*)')
       ->where('parent_id=?', $this->id);
echo $this->fetchRow($sql)->num;

At PHPoet, we have developed an e-commerce plugin for WordPress called PHPurchase. PHPurchase adds e-commerce functionality to the popular WordPress platform. So now you can sell products from your blog or you can run your entire website on WordPress and create your own online store. To see PHPurchase in action, take a look at QuietHeadphones.com, an online store selling headphones.

You can use WordPress and PHPurchase to easily set up your own online store. By now, most people have heard about WordPress. If not, WordPress is free web software that you install on a web server and it lets non-programmers manage their own website. You can run your own blog, add/edit pages of your own website, and now you can even run your own e-commerce store.

There are many web hosting companies out there where you can install WordPress with just a couple clicks from the control panel of your hosting account. If you happen to have a web hosting account that does not offer WordPress, you can very easily download WordPress for free and install it on your own. You basically just upload the WordPress folder that you can download from WordPress.org, enter in a couple configuration settings and you can be up and running in about 5 minutes. Once you have the initial installation of WordPress running you may want to customize the look of your website by downloading a theme. WordPress themes let you change the entire look of your website very easily. There are tons of free themes available. There are also “premium” themes that generally cost around $50 – $100. Or you could hire my company WordPress development company to develop the site for you. Then, once the site is developed, we will train you how to manage the entire site on your own.

By default, WordPress does not have any functionality for e-commerce so you will want to get the WordPress e-commerce plugin. PHPurchase let’s you sell digital products like music files, or other types of digital documents as well as physical products that you would ship to your customers. You can also sell services. For example, if you wanted to offer freelance writing services, logo design, or basically anything, you can easily set that up with PHPurchase. PHPurchase will work with PayPal or you can set it up to take credit cards directly on your own website. PHPurchase is very secure and doesn’t store credit card information so you don’t need to worry about hackers or anything.

There are several other e-commerce plugins out there for WordPress, but we were never able to find one that satisfied our needs. They either force you to use fancy grid layouts or organize your products by brand or category. If you are only selling a small number of products then you don’t want to be forced into a layout designed for large stores with lots of products. We designed PHPurchase to let you use WordPress to configure your entire store and use PHPurchase to handle the e-commerce. PHPurchase may be the only WordPress e-commerce plugin with professional level support. It is easy to set up and even comes with some videos showing you how to configure all the aspects of your online store like shipping prices, promotions, etc. If you run into any trouble. PHPurchase is supported by PHPoet a web development company specializing in WordPress. So you can quickly get answers to your questions. We are also available to build your site for you and train you how to manage it once it’s online. So if you are looking for a way to make some extra income or if you want to start your own home based business, WordPress and PHPurchase are certainly worth looking at.

If you need to use the setTimeout() function to call a javascript function that accepts a parameter you might be tempted to use syntax like

setTimeout('functionName()', 1500, param1, param2, etc); 

And you would probably have success until you went to test your site in Internet Explorer. Firefox seems to be able to handle the extra parameters on the end of the setTimeout() call but IE simply sends undefined variables to the function you are calling and your script dies.

Here is the solution – use closures! They are a little tricky to understand if you are new to the idea but, in a nutshell, you are assign a function to a variable. Normally you assign numbers, or strings to variables – well you can assign functions to variables too. Here’s how:

setTimeout(function() { delayedFunctionName(param1); }, 1500); 

This causes the function delayedFunctionName(p1) to be called with a 1.5 second delay AND the p1 parameter actually gets a value!
