I searched for the transport error code in the New Error message and it seems that my host must be blocking their own webserver IP address

Are you sure you need to Authenticate? Sometimes depending on your setup you can just do:
MailMessage message = new MailMessage("mailer@testdomain.com", "testreciever@gmail.com", "feedback", "WOOT!");
SmtpClient mailClient = new SmtpClient("mail.testdomain.com");
mailClient.Send(message);
message.Dispose();
If you do need to Authenticate, have you tried code like:
mailClient.Port = 25;
mailClient.UseDefaultCredentials = true;
Hope that helps.

Here's one for the hall of stupid! I changed the domain to "localhost" instead of "mail.testdomain.com" ...
Wish they would have said that the web and mail server were the same machine!

Cookies are not secure, generally speaking session variables are. If you have sensetive data to be stored use the session, and make sure the session data is stored server-side.
Using cookies will reduce the memory footprint of your application on the server, but will add more data for the user to download. Its a tough question if you have large amounts of data to store - who takes the hit, user or server? I'd normally opt for the server (sessions), its easy to throw RAM at a machine, not as easy to extend users patience while a page downloads.

I will try to explain you in more details.
Session Vs Cookies
1) Session objects are stored in server memory e.g IIS memory on the other hand cookies stored at client machine.
2) Now when it is stored at client machine then we can have some concerns like
security, cookieless browser, user delete the cookies etc...
3) Issues with Session is, if your server goes down then you loose the session value if you are using inproc session mgt.
4) Session can not be used in case of web farming (Load balancing)
SO now it is upto you as application arch, where you want to store....And if you need more information then google it...Session Vs Cookies....
Thanks

thanks for reply ...its very clear
its new thing i learnt that " session cannot be used in webfarming "<--can i know why? then only way to solve the issue then is to use cookies?
i want to make my question once again clear that i am asking when to use what ,
may be some realtime scenarios if possible or what tradeoff or tips we can use for making a balanced application .maybe like what data can be used for sessions data and what data can be used for storing in cookies?
anyone more who want to share your views more about when to use cookies and when to use sessions are please welcome to write it down here......
thnks for your effort and time in advance

What do you mean with 'launch' the pdf file?? Do you want to open it?? And do you want to open it server side, or client side??
I reckon you store the byte[] in a file and link to that file using a hyperlink...

Why would he work on YOUR problem. Surely you should be working on your problem. The people here are only here to help when they can. Not to do other people's work for them.
