No Mail Relay

I saw a lot of spamers use my email server to send their Junk mails.
To stop it. I have to set up my IMail server to No Mail Relay.
Previously I wrote Stop third party email relay
Now, I stop the third party mail relay totally.
No Mail Relay
With this option, IMail will not relay mail through the server unless the sending user authenticates. On the SMTP Security tab, make sure that ‘Disable SMTP “AUTH” reporting’ is NOT selected. (In version 8 and higher, this option is on the SMTP Advanced tab).
No Mail Relay is the best solution for customers who are unable to choose ‘Relay mail for Addresses’ because their users connect using dynamic IP Addresses.
After setup in the server side, inform all email users to config their email client software.

Session variables problem

I met the session variables problem in IIS6.
I use global.asa as web application.
Same coding, it works under IIS5 of windows 2000 and IIS5.1 of windows xp, but it lost session variables under IIS6 of windows2003.
Sometimes I need to log in more than one time to get in the required page.
Tonight, I solve the problem.

Microsoft introduced several new features into Windows 2003/IIS6
webserver that affect how sessions and application pools are handled.
*Application Pools*
Most webhosting companies host multiple websites in the same application pool. When resources are maxed out for a application pool IIS 6 starts to recycle these sites causing application variables to be lost for those recycled sites.
If you are experiencing application/session loss symptoms then we would recommend asking your webhosting company to place you in your own application pool with all recycling options disabled and the recycle worker process set to recycle only once during the day at a set time.

I made a new applicaiton pool which is used by my application only.
So the problem disappeared.
Steps as below:
Step 1:
Add new application pool.

In-Out Board


This is a web-based In-Out Board program.
It is totally free to download, use.
Pentacle (In Out Board) was started as an idea I had in the early part of 2003 when I was supposed to be running the intranet site design side of a local insurance brokerage company.
It was almost 2 months from the initial idea till the launch of Pentacle on the April 2003. During these 2 months much time was spent in researching, planning, designing, developing applications, and writing tutorials and articles.
After used internally about 2 years, I think about to share it with all other people need in/out board on their desktop .
Pentacle Free Limited Version was started, and is improvd time by time. I hope it is alway be on your desktop free of charge.

Pagerank stop working

After I installed the new version Google Toolbar 3.0.123, abut 2 hours later, I found that Page Rank information are always unavailable. Even the site:
In the begining I thought it happened because of the new version’s problem. I downgrade to Version 2.0. Still unavilable.

I checked the help of Google Toolbar. It said:

My PageRank button is always grayed out. Is it broken?
The PageRank button will appear grayed out on sites that are not currently included in the Google index. As a test, if you visit, the PageRank bar should show a score of 10/10.
If it does not, it is most likely because the PageRank feature is incompatible with some aspect of your system. Often, users who work behind a firewall or proxy encounter this problem.
Unfortunately, we do not have a solution to pass along at this time. Our Toolbar engineering team is investigating this issue, and we hope to release an improved version of the PageRank feature in the future. In the meantime, we would recommend that you disable PageRank by performing the steps below:
1. Click on the “Options” button on your Toolbar.
2. Un-check the box next to “PageRank display.”
3. Click “OK.”

Today, I know that not me only. A lot of people are in same situation.
PRchecker reported that:
28 May, 2005 – Update: have stoped their pagerank service today, and

ALL the sites have ZERO rank now. We do not know if this is a temporary problem, but we hope it is, and we hope they will resolve this issue in several days, we’ll post an update when it is available.

In the Google Toolbar site, you can find no pagerank field in the toolbar image the provided.
This is the image from their site:
I think pagerank will retire soon.

Wireless Network Concern

Now more and more network build by wireless equipments.
There are still something concern.
1) What is the range of wireless?

Types of Wi-Fi Network
Protocol Maximum Speed Average Speed Wireless Range
802.11a 54Mbps 27Mbps 12m indoors, 30m line-of-sight outdoors
802.11b 11Mbps 4.5Mbps 30m indoors, 120m line-of-sight outdoors
802.11g 54Mbps 7Mbps (in compatibility mode), 16Mbps (with other 802.11g devices) 30m indoors, 120m line-of-sight outdoors

Standard construction walls can reduce the transmission distance by as much as 50%.

So, put the wireless router in the center of the house.
