We are sending email from our asp.net application to customers. but sometime we may have wrong email address of customers so it may bounce back.
so while i am sending the mail to the email address...is there a way i can know that the email address is valid
(for instance: to check if email@example.com is an existing email in gmail and another check is to see if firstname.lastname@example.org is a valid domain name)
...so that we can log it in our database or for record purpose..so that we know that the email did not get sent out for that customer?
also, we would like to track if there is any bounce back of emails.
Attaching a simple test smtp email application just to show what i was trying to do.
and this thread reflect the exact same question i have.
i am looking at what the alternative would be for this. (exchange server??) ,,
