Can anyone help me sort out the problem of validating an email id. I just want to know whether there is any way to find out to check whether an email id exists or not,without actually sending a mail.
I am getting the result as the mail id is valid for non-existing mail ids.I have used the smtp cmds within the code. Pls.....help me out in resolving the problem.
Thanks one and all for ur replies.Is there a way to find out by sending a mail and capturing the reply within the code.

I'm afraid you can't do it. There is no central registry of email addresses, so you can only identify a valid email by sending them a mail and getting them to reply back.

Checking the MX record notwithstanding. Granted not a perfect method for numerous reasons, but one step in between email-address-looks-valid and send-email-address-mail

It would be a fair start, but as you note - not perfect.

The only sure fire way is to send an email to the address.
You can use regex to check if the address is technically valid, dns lookup to verify the domain exists and has mx records but that's about as far as you can go without sending an email.

How original. It's urgent - because nobody ever posts here and says "Take your time. I have all the time in the world to get the answer to this."
With only the filename, you have to walk the entire directory structure, looking for names that match it. You could have written the code in the time it took you to post this.

You were given the answer. If you can't implement it, then that's not my problem.

You need a clue more than anything else. He gave you the answer, but I seriously doubt he'll actually write/test the code for you.

I can't speak for Pete, but for the proper remuneration I could. My rate for YAFM code is $500/hour, 4 hour minimum. All new customers must pay 100% prior to source delivery.

If you can't follow the rules then don't post the question. Mouthing off at senior members will get you little help ever here.

It's my fault. I engaged with a troll, so I should be named and shamed.

Don't worry about it - nobody got hurt in the cross fire, and a 5 for the sentiment.

This has nothing to do with a WebRequest. If your message subject was more accurate, you'd have more people trying to help.

Less than 10 seconds with Google found this[^]. You need to install .NET 3.5 SP1 for the Entity Framework.

Hello everyone,
I have some detailed web services questions, for example some WSDL or SOAP field. I am not sure whether to ask such question is suitable for this forum.
If not, could anyone advise some other forum or maillist please?
thanks in advance,
George
