I understand your reluctance to use third-party tools, because I encountered a very similar problem (with very similar requirements) working on a project for one of my customers.

Email verification is a complex process, and it requires several validation levels:

1. The email address itself must have the correct syntax, so a regular expression check is needed.

2. The email address must reference a valid domain name, so a DNS query is needed.

3. The email address must reference a domain name that accepts mail server connections, so an SMTP connection is needed.

4. The email address must reference a valid inbox on the receiving mail server, so a send (or send attempt) is needed.

You don't have to use the components from this particular developer, but you might his descriptions of the above levels sufficiently detailed to implement your own solution using your own code. Refer to the section titled "Understanding Validation Levels" on this page:

http://www.afterlogic.com/mailbee-net/docs/getting_started_with_address_validator.html[^]

Speaking from my own experience, it is certainly possible to write the code to implement all four validation levels, but it turned out to be too expensive and too time-consuming for my customer, and so I was able to convince them to license software components from that developer.
