How can I check if an email address actually exists?
I have a list of email addresses which I want to screen for dead email accounts (without sending an email msg with a hyperlink). Is there a web-service for this? Or C# code (which I prever instead of sending the data to someone else)?
In addition to the process of regex syntax validation of Email Addresses entered by users, I'm trying to check if the entered email address is a real one and does exist?The best I could achieve is to "Ping" the host the email address is associated with. But there are some other terms in the industry like Handshaking with Email Server, etc.not necessarily with 100% confirmation accurary!

how do I grab an email address from a web form and email to that email address with the link to a webform?
View 5 RepliesI have managed to expose the MEX endpoint of my WCF service and I can access it with the address like [URL] (example) and get the WDSL. So no problem there.
However, my WCF test page shows the address wrongly by using the server's name instead of the DNS name. And if I click on the link on the test page it won't work (can't get WSDL).
The WCF test page looks like this:
MyService Service
You have created a service.
To test this service, you will need to create a client and use it to call the service.
[URL]
The WCF service is hosted in IIS6. I would like to have a test page with the correct WSDL address so users can see the WSDL quickly in the browser just by clicking on the WSDL address.
In short: How can I change the MyServerName to inter.mycompany.com on the WCF test page? Can this be specified somewhere in the Web.config?
