How does Email Scanning Work?

Its a known fact that the emails we receive/ send are scanned before they reach us/intended recipient.
I thought of putting below a diagram describing how the entire stuff happens.

Lets first discuss how the entire flow works in case of Incoming Mails.

• All the incoming mails ( infected/clean) irrespective of there status are sent to the Antivirus software’s temporary folder where they are scanned for infections by the software.
• In case, the Antivirus is not able to clean the mail, the item is moved to the quarantined items folder.
• All clean/disinfected mails are then sent to the Exchange server from where they can be pulled by the Email Client.

In case of Outgoing mails, the following flow holds good.

• All mails from the Email Client are pushed to the Exchange Server.
• The mails are then moved to the Antivirus Software’s Temporary folder for scanning.
• In case, the mail is found infected and is out of the scope of clean function, its moved to the Quarantined Items Folder.
• All clean and disinfected mails are sent back to the Exchange server from where they are rolled out for the intended recipients.

Please note that this is a pseudo algorithm describing how Antivirus Softwares actually work. This might differ from software to software.

Tutorial: Find the IP Address of sender in Gmail.

Yes, you read it right. You can do it. This is the theory behind it; When you receive an email, the email comes with important information called the header information. The header information has entry of the IP address of the sender. Here is what you need to do to uncover this hidden information.

1. Using your id/password, login to Gmail.
2. Open the mail for which you wish to find the IP of the sender.
3. Click on the inverted triangle placed just next to Reply. Click on Show Original
4. You now need to look for Received:from followed by the IP within square brackets [ ] e.g. Received: from ge3.i-nonymous.com (ge3.i-nonymous.com [82.96.97.51])
5. Also importantly, there are times when you might find multiple Received: from entries, in that case, please select the last one as the valid choice.

Similarly, IP Address of the sender can be tracked in Yahoo Mail and Hotmail as well. Will discuss about it in my coming posts.

P.S: This trick wont work on mails sent from Gmail. [Thanks to BGM for pointing to this]

Gphone: Is it coming?

I talked to one of my inside sources at Google today. He spoke on conditions of anonymity, but the guy is someone I trust implicitly. He said that he was baffled at Google’s apparent internal confusion on the GPhone issue – that they’ve actually demo’ed the thing in public before.

He said that the Google (applications) Suite is going to play a huge role in the usability of the GPhone, and the thought process behind it’s functionality is less about beating the iPhone and more about beating the $100 Laptop, which provides a huge clue behind what will be the pricing structure on this. more>>

Excellent list of resources for Web2.0

Just came across an excellent resource list on Web 2.0 Stuff compiled by Everything Web2.0 blog. The list has amazing resources to help you build better.

Probably the most interesting ones are the frameworks, platforms and libraries for typical 2.0-stuff .
But watch out for all other pearls: bug & issue trackers, business intelligence solutions, database solutions, catalogue wares, design toolboxes, enterprise solutions, media editors, hosting & domain management & testing tools, media management solutions, mobile content delivery tools, site tour builders, hardcore telephony solutions, voice recognition tools, and more incidental code snippets, like URL shorteners, widget builders, Ajax & RIA apps.

Check out the complete list here

Google Maps add more Embedding

Google is always believed to keep its processes simple and in sync with its other LOB’s ( lines of businesses). Going ahead with that, google has made Google Map embedding also as easy as embedding a Youtube Video.

Here is how to actually embed that map instead of just linking to it.

1. Go to the map that you want to embed (my example)
2. Click Link to this page in the upper right hand corner.

3. Either copy the code from the Paste HTML to embed in website section or even cooler is to click the Customize and preview embedded map link to change the size of the embedded map.

Once you have pasted this code, the Map gets embedded exactly as you embed a Youtube Video.
Cool naa..

Recovering Hard Deleted Items in Outlook 2003.

We talked about Recovering Permanently Deleted emails from Outlook 2003 in the previous post. However, if you have deleted your mail items the hard way, i.e. by pressing SHIFT+DEL the mail is not sent to the Deleted Items folder and therefore the previous trick fails.

By default the Recover Deleted Items functionality is only enabled on the Deleted Items folder in a user’s private folders; items that are hard deleted cannot be recovered. However, the good news is that this can be changed by making a small change to the Registry.

Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Follow these steps to modify the Registry

1. Start Registry Editor (Regedt32.exe).
2. Locate and click the following key in the registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Client\Options
3. On the Edit menu, click Add Value, and then add the following registry value:
Value name: DumpsterAlwaysOn
Data type: DWORD
Value data: 1
4. Quit Registry Editor.

That’s it. Now you can recover your hard deleted mails as well. 🙂

Recovering ‘permanently’ deleted email in Microsoft Outlook 2003

Today morning i mistakenly deleted some of my very important mails from Microsoft Outlook 2003 client. At my workplace, i use Microsot Outlook 2003 client interacting with Exchange Server. I was able to recover my mails from Outlook, thanks to the policy settings on Microsoft Exchange Server and this small trick which i write about in my post below.

Now, in order to recover them, you just need to go to Microsoft Outlook, and click the Deleted Items Folder, then you need to go to Tools –> Recover Deleted Items. All the items that you have deleted within the time frame set in the policy should be available for you to select. Just select the one’s you want back and hit the recover button.
Bingo!!! You are done.

However, there is a catch to this, you can’t recover the mails you hard deleted directly from other folders. I mean you pressed SHIFT+DEL and deleted a few mails from your Inbox. Unfortunately, this trick wont be able to cater to that. However, there is a way out for that too and i shall be writing about it in my next post soon.
