how to check the domain name of an email address...
i.e
in 4@4.com
validating 4(second one-domain) should return false if the domain is not exist again
if 4(first one) is not a valid user then also return false
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.

View 10 RepliesWhen validating an email address with the regex validation component, an additional RequiredFieldValidator must be added to ensure there is a value present.
I've mostly taken care of this with a CustomFieldValidator, and taking care of this with Javascript.
able to validate any email address based on the domain. For example, the system says anybody with a microsoft.com email address can create an account. Here is my code so far, it doesn't appear to work.
If Not Regex.IsMatch(tbEmailAddress.Text.Trim, "^([0-9a-zA-Z]([-.w]*[0-9a-zA-Z])*@" + mySetting.EmailDomain)

View 1 RepliesI'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?

View 1 Repliesi have an requirment where an user can enter multiple email address.
The validation should ensure that he should enter address in the format "something@abc.com".
my existing validation ensures that some text is entered before "@" symbol and "abc.com" is the domain.
@"w+([-+.']w+)*@abc.com$";
I would need my regex to check for the delimiter ";" between two mail id's .
valid: a@abc.com |
a@abc.com;b@abc.com|
invalid: a@abc.comm | a@abc.com,b@abc.com | @abc.com |
a@abc.comb@abc.com|

View 1 RepliesIn 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!

My Steps:

If edit case retrieve data and populate them in control like. txtemail.text = dbrec("email")
2.) submit action
