Hello, The security issue would be if one could verify 3rd party email addresses. An organization being lazy and cheap wanting not to verify users before granting them access is questionable organization decision, not a security issue.

Here's why this is a security issue. Our company administers a small "municipal-type" 802.11 network where for limited open-access the only form of ID we require is an e-mail address and a password. We simple don't have the resources to send out e-mails and then have verification and so forth. We are trying to prevent users from entering fake addresses into our system. We want at least a small amount of accountability. We would like to be able to do a quick check, say query an IMAP, POP3, or SMTP and check to see if there is actually an account at that address without sending a verification e-mail and waiting for users to click on a link or get something that bounces back. Does something like that exist? I do recognize that somebody can enter a valid e-mail address that does not belong to them, but we are trying to address one issue at a time. At this point we are just trying to prevent people who give us "dude () dude com" from getting on to our network.
