C# - Identify If An Email Address Is 'public'?

Nov 10, 2010

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?

VS 2010 - Having Email Address As Unique Identifier?

Mar 5, 2012

I'm creating a website with sql server db (built in membership database). I design it best possible. Im reluctant to use text fields as identifiers, but this is pretty much my first sql server db.

1. The user registers himself, at the same time registering his company/organisation. I dont think many of them will have the need to register themselves to other companys (N:N) but you never know (anyway not a main concern at the moment).

2. This user becomes a superuser (level1), with the ability to register other users to the same company (level2 users). Finally level1 can register level3 users to the same company.

So you see the identifier will be everywhere in the sql commands. There are quite a few N:N relations as well, which I guess slows it down even more. The selections typically retrieves a few hundred to a few thousand posts, but like I said, many will be in N:N relations.

Security :: Best Way To Identify All Users Currently Logged In?

Feb 10, 2011

I know how to identify the current user during a specific browsing session and can thus control the data, etc, made visible to that individual user. I also know how to find out how many users logged in within the recent past, using:

Membership.GetNumberOfUsersOnline()
.... which I believe calculates the number of users who have logged in within the past 15 minutes. However, I would like to know if there is any way to identify all the users who are logged in at a point in time. Is this possible?
