I was wanting to know how to basically send a request to an exchange/mail server and recieve something telling me if the email exist or not. How would I go about doing this? I see it being done but can not find any good examples so I can learn how to do it.

It's not being done. It's not possible. All you could do is send a test email and then check if you get a bounce message back. Which is not foolproof.

Well that sucks. I have trying to make this fool proof and say that email does not exist. Now whenevery I use my application and I send an email using the To. It works. When I add the CC emails it says that the mail server doest not accept emails. Well thats not true because it just accepted emails. It only does that when I use CC within the email. It is our work email and I am one of the sys admins up there and I can't figure out why it is saying that the mail server doesn't accept emails.

Take a look at RFC 2821 - section 3.5.1[^]
It explains how to verify an email address.
Basically you send a VRFY request and look for a 250 return code.

Do you expect someone to sit and write the C# version for you? 
Anyway, there are many online code translators. This[^] is one of those.

Can anybody recommend me a good spam filter for ASP.NET? Is there something that I can send a string and would return me a percentage (the possibility of its being spam)? Do I need to have my dedicated server (or VPS) to run a spam filter? In other words is there something that works with shared hosting?
Thank you for your suggestions ..

I doubt such a thing exists. Spam filtering and ASP.NET have nothing to do with each other. In any case, it's a war of attrition, you need to find a well supported project, or a commerical library that is constantly updated,.

But what about all those blogs and sites in ASP.NET? How do they handle spam?
|
|
|
|
|
Well, it's not an ASP.NET task, in that it's a general C# string parsing task. I guess they write something, or they have found a library for free or commercially. I am just saying, if it's free, be sure it gets updated often because those things would go out of date so fast....

I'm sorry, may be I didn't explain this right, actually I meant a spam filter that can be used with ASP.NET, this is what I meant. I think there must be something like that, I don't think every one who has a blog or site in ASP.NET has written their own spam filters. Besides some or probably the majority of those are not developers, so I don't think they wrote their own filters. Most probably they are using something like akismet which unfortunately not good for my scenario, there's also SpamAssassin but that doesn't work with ASP.NET (not completely sure but I have checked their website and there was nothing indicating it works with ASP.NET).

I guess you want something like CAPTCHA. In asp.net blogs and other things it is used for filtering SPAM so that we can block robots from spam.

Hi Ahsan, actually I already have a captcha in my app but I only use it on the registration page, I don't want to display a captcha every time a user adds a post, this is not really convenient.

anyone has a good Ajax code to upload image from local drive to server with progress bar showing the status?

There's a number of commercial controls that do this.

My task is, suppose text box of first name creted in Asp.net I type 'a' a related all the first names from the database is to be retrive and show as helper e.g on google site 'a' is typing a related words are generated.
I write the code for sending request through Ajax get values from database in datatable or dataset but it is not returning that datatable to the javascript from that I am calling that ajax. Next I have to show that value in that down box using javascript and it should be display in Asp page so only my that text box is to be refresh not whole page.
