I would like to identify if an email address comes from a public provider or is from an established business. I consider public email addresses to be things such as:
Open email service providers, such as gmail, hotmail and yahoo. Anonymization services, such as mailinator or dispostable.
I'm aware that there is no foolproof way to do this, and obviously any list based solution would require constant updates.
Is there a public listing or .NET library that can do this for me?
As working with ip address in Sql Server needs some Efforts than mysql b'cos it Doesn't has INET_ATON() functionality. even though we create a Function to do that. But as per Requirement if ip address and postid should be Unique with One Post Question. than its some more complex to implement. so i need a solution without compromising my Disk space, 4 Tiny int field for ip address can be used but comparison will be more Hard to achieve. b'cos it is a composite primary key.
I am building an email feature in my website (jobs site). By using this functionality, recruiters will be able to send emails to candidates. I want an option so that the user can also set 'From Address' and the email should be ANTI-SPAM compliant.
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!

i have an aspx page which on page load needs to populate a text box with the current users email address (user is in Active Directory), any body know how to retrieve the email address from Active Directory, i have read this article on the web but am a bit confused
string userName = Environment.UserName; string domainName = Environment.UserDomainName; //Set the correct format for the AD query and filter string ldapQueryFormat = @"LDAP://{0}.com/DC={0},DC=com"; string queryFilterFormat = @"(&(samAccountName={0})(objectCategory=person)(objectClass=user))"; SearchResult result = null; using(DirectoryEntry root = newDirectoryEntry(rootQuery)) { using(DirectorySearcher searcher = new DirectorySearcher(root)) { searcher.Filter = searchFilter; SearchResultCollection results = searcher.FindAll(); result = (results.Count != 0) ? results[0] : null; } } string primaryEmail = result.Properties["mail"][0] as string;
There is no defintion of rootQuery- so not sure what that is, or a definition for searchFilter

I just want to get the email address this way or get it from the membership system which ever is better.
I'm developing a website in ASP.NET & C# that will be on the www I have a contact form like most internet websites have and one of those textboxes is an email address. I wish to validate the email address so that the person enters a valid email in the form of [URL] What is the best way to do this?
We are developing an Intranet application that looks up some data for a user through hooks into Active Directory. However, our Network guys don't always enter in a users email address when creating a new user. Therefore, our user database is missing the email address for over half of our users. We have over 10,000 users, therefore asking them to enter 5000+ email addresses into each missing email address field in Active Directory isn't an option. I already know how to validate that an email address is correctly formatted using Regex. What I need is a way to lookup the email address entered in the email address textbox and see if it exists on Outlook/Exchange (or looking up the email address using the First Name/LastName would work). If it does exist then the address is valid, if it is invalid then the user typed in the wrong address. I've tried to do something with CDO, but have had no luck. We use Outlook 2003 and ASP.NET 2.0.
I'm using Facebook connect on my site. If a new user connects through FB i create an account for them and all is fine. What i would also like to do is check to see if they already have a registered account.
So if someone connects that has not logged in but has an account i would like to be able to locate the account in my application a link it. I hoping this could be done via the email address?
I'm trying to extract the domain name from an email address. For example if an email address is info@mydomain.com i want to extract 'mydomain' from the string.
I have some C# code which does this:
[Code]....
This works fine - except if a user has an email address which contains a dot '.' (e.g. fname.lname@mydomain.com) then it throws the following error:
Length cannot be less than zero.Parameter name: length Line 29: int startIndex = strEmail.IndexOf("@");Line 30: int endIndex = strEmail.IndexOf(".") - startIndex;Line 31: string domain = strEmail.Substring(startIndex + 1, endIndex - 1);
The problem is the first '.' in the email address is causing it to calculate the string from the incorrect position.
Is there a way to retify this - or does anyone know of another solution to extract the domain name from an email address?
By default, Membership API uses a separate username field to login users. I would like to use the email address for users to login. Is this a good idea?
How would I modify the Login, Register a user, Forgot password control to support this?
I'm trying to error handle a registration aspx/c# page on my application and want to run a check whether the email address that a user has tried to register already exists as the email address is used as a primary key in my database.
I have tried IF NOT EXISTS/IF EXISTS but these dont give the desired effect so was wondering if there was another way around it?
