Thanks to everyone for their response.

I'm working with a mature app, but it lacks email verification, therefore it opens itself up to account creation with an email address that doesn't exist.

Before the account is created, I would like to be able to, at a minimum, ping the email address to be sure it exists.

Pinging the existence of the domain name would not be sufficient when inappropriately using the domain name of popular free email address sites.

Hopefully, the email address pinging can distinguish between non-existent addresses versus full mailboxes.

Ideally, I would like to have email verification integrated at a later date.

Also, is there a downside to pinging the email address and waiting for a response before the software continues onto the account creation (or the denial thereof)?

Thanks.
