I tried in those manners also, not only that even I am not able to send text mails also if the message length greater than 10 lines / 1 KB size. I am so bored/sad of this problem, nobody able to solve this problem, even bsnl customer care also not caring about this. I doubt the problem is in router settings (sending data packet size limit etc.) but I dont have clear knowledge about it.

Sankar singh,

This is because of a MTU issue in your PC. MTU is not but the Maximum Transmission Unit. If this is high or inappropriate, some attachements could not be opened or mails could not be sent. To get rid of this, you need to use, a tool Tcp Optimizer

helo ezhilaksh,
thank you very very much. I solved my problem due to your suggestion.
Its right that there is inappropriate MTU Settings found in LAN Settings. I corrected them after downloading TCP Optimiser Software as you mentioned.
I want to Share the steps I followed with others :
1. Open TCP Optimiser
2. I set my connection speed to 2,000 kbps as I got 2 Mbps
3. In General Settings : click on custom settings at bottom
3. Go To MTU and put 1500 there for first time.
4. and MTU Discovery : yes, Black Hole Detect : Yes, Selective ACKs: yes, Max Duplicate Acs: 3
5. Next I went to the tab "Largest MTU" and I started the test with speedguide.net, I got the maximum MTU response of "1453" for my connection, after that it was showing "Request Timedout" message.
6. Again I went to General Seetings : MTU : and overwrited 1500 to 1453
1453 is the appropriate MTU Setting.
Next I applied them restarted the p.c and it works all fine now. thanks once again.
