Email Verification in VB
Posted on 2002-07-12
Here is what I need to know how to do.
I need a quick and dirty way of verifying email addresses.
Basically, this is the sequence I want to go in:
1.) Read in records from database
2.) Parse out the domain portion of the address
3.) Do a MX Lookup, to get mail server name
4.) Login to mail server to verify the user exists on the server
Here is what I have done so far, I have all of the code that does the SMTP commands to verify the user on the server, I just need the rest. IF anyone has any suggestions where I can find libraries or controls to do teh MX lookups or anything please comment. I am willing to go up to 300 points for this questions if someone has a complete answer. I even am willing to put a cash reward for the solution if it is really good.
