To configure Thunderbird, please follow these steps:

1. In Thunderbird, from the Tools menu, click Account Settings.
2. From the Account Settings screen, click Add Account.
3. Select Email account and click Next.
4. Enter your name and email address and click Next.
5. Select POP as the incoming server type.
6. Enter the Incoming Server, mail.domainname.com.

9. Click Next.
10. Enter your full email address as the Incoming User Name and click Next.
11. Enter an Account Name and click Next.
12. Confirm the information is correct and click Finish.

This does not mean that your email account was compromised. It means that the sender has fooled the mail client into believing the email originated from a different address.

This is usually done for malicious reasons, either to distribute unsolicited email or to distribute email viruses. Unfortunately, there is no real way to prevent spoofing from occurring. If you receive an email that has questionable content, it is recommended to delete the email message or use an antivirus program to scan the message before opening it.

1. In Outlook 2007, from the Tools menu, select Account Settings.
2. On the E-mail tab, click New.
3. Select Microsoft Exchange, POP3, IMAP, or HTTP and click Next.
4. Check Manually configure server settings or additional server types and click Next.
5. Select Internet E-mail and click Next.
6. Enter the requested information:
   • Your Name: your name
   • Email Address: the email address the messages will be sent from

What is Yahoo thinking??? Recently Yahoo has started “greylisting extremely deprioritizing” almost every email that goes through their mail server. Greylisting This is a way of attempting to block SPAM. Yahoo mail denies the first every delivery attempt of an email (451 Message temporarily deferred – 4.16.50) from deprioritized mail servers. They assume that SPAMers don’t try sending the same email twice, so they put the ip address of that email server on a list and then if the delivery is retried within a short amount of time, they assume that it is a good email.

Now here is the downside. Do you think that spammers care one wit whether they send a “spammy” email once, twice or a thousand times? No, they don’t. All Yahoo is doing is increasing the problem. Now instead of being hit by one SPAM email, you’ll get three.

Since about October 16, 2006 they have been “overly aggressive” in blocking emails.

Yahoo! Mail has become more aggressive in its acceptance of SMTP connections and denies connections by IP address when these connections do not conform to Internet standard practices.

This results in people that have been sending email to the same person for the past 3+ years to suddenly not be able to send email. Even when the sender is “conforming to Internet standard practices.

How to fix the problem (sortof)

Yahoo gives some basic “do these to fix the problem “:

• Remove email addresses that bounce
• Examine your retry policies
• Pay attention to the responses from our SMTP servers
• Don’t send unsolicited email (duh!)
• Provide a method of unsubscribing
• Ensure your mail servers are not open relays.

Unfortunately, even after completing the checklist above, servers are still being greylisted deprioritized. Yahoo suggests that you use their “form” so that they can help you diagnose the problem. Well three different forms later, the only correspondence you will receive is an “auto-responder” that says:

Thank you for contacting Yahoo! Customer Care to answer your question. A support representative will get back to you within 48 hours regarding your issue. Until then, feel free to visit our online help center at http://help.yahoo.com/ or answers if you have not already done so.

Also install DomainKeys to help fix the problem

Dig a little deeper and you will find that you should install DomainKeys (you should have already installed SPF records so that you can send to AOL accounts) to sign your emails from a specific domain. However, even once this is done, you will still get some 451 errors.

The long and short of it is that you get what you pay for…

• Yahoo is not communicating with administrators even after they submit multiple request forms.
• Yahoo is not delivering messages even though they send the response back that the “message was temporarily deferred” (Which sounds like it is just waiting to send the message, but will get to it eventually).
• In an attempt to block spammers, Yahoo is blocking an extremely high number of “good” emails.

Beginning

First of all you need to open the mail program and then select the “Tools” option. From this menu select the “e-mail accounts” option. This allows you to setup and configure your mail accounts.

Adding a new mail account

This menu gives you access to add a new email account, and to view/change your current email accounts already created. You need to select the “Add a new e-mail account” option, then click Next.

Select your name

Here you need to select the type of account you wish to create. You should select either POP3, or IMAP. With POP3, it will download all of the mail to your computer. With IMAP, it will leave the mail on the server.

Select your reply address

On this screen, the name you choose as “Your name”, will be the name people see the mail being sent from. The address you use in “E-mail address”, will be the email address people see the mail being sent from.
Most people choose the email address they are sending from. For example: if your email address is me@me.com, you will most likely want the reply address to be me@me.com

There are also two server addresses you must complete, one for incoming mail and one for outgoing mail.

For some Internet Server Provider (ISP), there is a restriction in using SMTP server and you need to use their ISP SMTP server for you to send an email. In the incoming mail server field, you need to enter: mail.yoursitename, so if your address is me.com you want to use mail.me.com
For the outgoing mail server (SMTP) you should consult your ISP (the company who provides your Internet connection). Most ISP’s provide an SMTP server of the form: smtp.ispname or mail.ispname If they cannot provide you with this, we can offer SMTP as an upgrade.
The logon information is the username/password you must use when collecting your mail. If you have created your own mail account via the siteadmin interface you should set the account name/password to the email address/password you chose. Otherwise you should use the email address/password provided in your welcome email.

All done

Simply select finish and you are now all ready to receive your email through outlook.

Below you’ll find a list of the sites I’ve visited to learn more about Javascript and CSS compression. Most of the descriptions below are taken from the developers of the example.

Javascript and CSS Compression

Bundle-Fu – Bundle Your JS/CSS Assets in 10 Seconds or Less
“Web 2.0 sites have lots of tiny javascript/css files, which causes one extra round trip per file to the server and back! This is bad! Bundle-fu throws it all up into a big package and sends it out all at once. ”

Make Your Pages Load Faster by Combining and Compressing Javascript and CSS Files
“About six months ago I noticed the pages generated by the content management system were in itself very clean and small, but that these pages still took a long time to load for new visitors. Even on a fast internet connection it took more than 8 seconds to load a basically empty page. The server generated the page in about 350ms, so that wasn’t the problem. The problem turned out to be a combination of two things: each page used more than 12 different css files because each plugin supplied its own css definitions and because the use of the rather large prototype and scriptaculous javascript libraries which also consists of a couple of different files. Now that an article about the same problem featured on the Yahoo! User Interface blog, I decided to make my solution public, so others can benefit from it.”

Faster Page Loads – Bundle Your CSS and Javascript
“Have you ever watched your status bar while you wait for a page to load and wondered why several files seem to be downloaded before you see anything at all on your screen? Eventually the page content displays, and then the images are slotted in. The files that keep you waiting are generally the CSS and Javascript files linked to from the “head” section of the HTML document. Because these files determine how the page will be displayed, rendering is delayed until they are completely downloaded..”

Pack:Tag
“A serverside static-resource compressing JSP-Taglib. Could cache ad hoc compressed JavaScript or CSS in memory or in a file. The compressing-algorithms are pluggable.”

AJAX and CSS Optimization
“Roland pointed me to an article about the amount of Javascript on digg.com’s home page. Seems a few Digger’s found it interesting. Well here at Zimbra we’ve got tons of Javascript and CSS in our AJAX web app. I decided to try an experiment to see if the techniques we use for Zimbra, a rather large AJAX app would help a site like digg.”

Javascript Compression

Serving JavaScript Fast
“With our so-called “Web 2.0″ applications and their rich content and interaction, we expect our applications to increasingly make use of CSS and JavaScript. To make sure these applications are nice and snappy to use, we need to optimize the size and nature of content required to render the page, making sure we’re delivering the optimum experience. In practice, this means a combination of making our content as small and fast to download as possible, while avoiding unnecessarily refetching unmodified resources.”

JSMin – The JavaScript Minifier
“JSMin is a filter which removes comments and unnecessary whitespace from JavaScript files. It typically reduces filesize by half, resulting in faster downloads. It also encourages a more expressive programming style because it eliminates the download cost of clean, literate self-documentation.”

YUI Compressor
“The YUI Compressor is a JavaScript compressor which, in addition to removing comments and white-spaces, obfuscates local variables using the smallest possible variable name. This obfuscation is safe, even when using constructs such as ‘eval’ or ‘with’ (although the compression is not optimal is those cases) Compared to jsmin, the average savings is around 20%. The YUI Compressor is also able to safely compress CSS files. The decision on which compressor is being used is made on the file extension (js or css).”

GZip output compression with AJAX
“To make page downloading quicker, I added GZipStream into the Response filter.”

Javascript and CSS Compression With Java

LZ77-Algorithm-Based JavaScript Compressor
“LZ77 is known as the basic loseless data compression algorithm. It is used very wide. For example, common .png, .zip, .gzip, .jar, .war file formats use LZ77 compressing algrightm. Here is a Java implementation of such LZ77 algorithm. And by using the Java2Script Simple RPC technology, it sends the string, which is going to be compressed, back to server, which is a Java Serlvet container, and the server runs LZ77 algorithm to compress given string, and then packs compresed string back to browser side. As this compression is specially designed for JavaScript sources, it gives options for how JavaScript codes are compressed. In most cases, this compressor compresses JavaScript at the ratio of 40%~60%. And if you check off those JavaScript options, this compressor can compress any given string.”

Combine and compress your CSS and Java
“So you have your site running on the latest and greatest Java libraries, but your supporting CSS and JavaScript files are really starting to slow things down. You’re no JavaScript expert, so what do you do? Lucky for us some other people have already encountered this problem and have a great solution.”

Javascript Compression With PHP

Packer JavaScript in PHP
“PHP Version of the Dean Edwards ‘s Packer de Dean Edwards, a JavaScript Compressor/Obfuscator.”

Javascript and CSS Compression With Rails

Rails plugin: Blazing fast page loads through bundled CSS and Javascript
“I recieved an interesting Sitepoint newsletter the other day which talked about bundling CSS and Javascript ressources (or “assets” like that’s called in Rails talk) to achieve faster page loads. This caught my attention specifically because I experienced the need to repackage many small CSS files on the fly a while back when I worked on a large CMS-type system. Skimming through the PHP source article and code I thought that something similar could be done as a Rails plugin pretty easily and elegantly. I couldn’t resist, sat down and started coding away … so here are my results.”

Javascript Compression With Rhino and Maven

Rhino and Maven for JavaScript Compression at Build Time
“AJAX-based Rich Internet Applications (RIAs) make heavy use of JavaScript. To improve the user experience of RIAs we can minimize the number of (JavaScript) file requests and reduce their size.”

ShrinkSafe
“ShrinkSafe is a JavaScript “compression” system. It can typically reduce the size of your scripts by a third or more, depending on your programming style. Many other tools also shrink JavaScript files, but ShrinkSafe is different. Instead of relying on brittle regular expressions, ShrinkSafe is based on Rhino, a JavaScript interpreter. This allows ShrinkSafe to transform the source of a file with much more confidence that the resulting script will function identically to the file you uploaded. Best of all, ShrinkSafe will never change a public variable or API. That means that you can drop the compressed version of your JavaScript into your pages without changing the code that uses it.”

MobilVox Maven JavaScript Plugin
“The MobilVox Maven JavaScript Plugin (maven-js-plugin) is a Maven Plugin that manipulates JavaScript in a web application. The currently implemented goal is compress which compresses all JavaScript in a Java web application.”

Compression Research

Performance Research, Part 1: What the 80/20 Rule Tells Us about Reducing HTTP Requests
“This is the first in a series of articles describing experiments conducted to learn more about optimizing web page performance. You may be wondering why you’re reading a performance article on the YUI Blog. It turns out that most of web page performance is affected by front-end engineering, that is, the user interface design and development.”

Minification v Obfuscation
“JavaScript is a load-and-go language. Programs are delivered to the execution site as text (not as executable or semi-compiled class files) where it is compiled and executed. JavaScript works well with the Web, which is a text delivery system, because it is delivered as text.”

Optimizing Page Load Time
“It is widely accepted that fast-loading pages improve the user experience. In recent years, many sites have started using AJAX techniques to reduce latency. Rather than round-trip through the server retrieving a completely new page with every click, often the browser can either alter the layout of the page instantly or fetch a small amount of HTML, XML, or javascript from the server and alter the existing page. In either case, this significantly decreases the amount of time between a user click and the browser finishing rendering the new content.”
