Its ok to worry about things, and thanks for the concerns but we

I am looking for cocoa pointers.
So far as I understands I need to make a connection to a mail host
port 25
and act it if it was a telnet connection. Right?
A large number of networks now block outgoing connections on port 25
to reduce the amount of spam originating from their network (they will
either require you to use their own designated relay, or fill out a
form saying you know what you're doing and you have a reason to need
it, etc).
Also, what you are proposing is not to "verify" an e-mail address.
You're sending a blank e-mail to the recipient and seeing if it fails.
Even if the e-mail is accepted for delivery by the designated mail
exchange, and you don't get an error, you don't know that the e-mail
address is valid. You may very well get a failure notice delivered in
response at a later date.
Let's recap:
1. What you're doing won't work.
2. What you're doing will have other side effects which users will
find annoying.
Perhaps you should rethink your approach.
