email-exists
Check whether an email address exists.
This module checks whether an email address exists by connecting to the mail server and pretending to send an email (_but not actually sending it, of course_).
For checking whether an email is syntactically valid, please use
hapijs/isemail.

options with the following properties:
sender : _required_; the sender's email address for the MAIL FROM command
recipient : _required_; the recipient's email address for the RCPT TO command
timeout : _default =_ 3000; the timeout in milliseconds for the Telnet connection
debug : _default =_ false; whether to print debug messages to the console
returns a which:
resolves with one of the following objects:
INVALID_SYNTAX: Represents a 553 indicating that the mailbox name is not allowed due to invalid syntax
NOT_FOUND: Represents a 550 indicating that the mailbox is unavailable,
MAY_EXIST: To prevent clients from discovering all available addresses, servers may respond with false positives; therefore, this result is deliberately named "may exist", indicating that it is highly likely that the address actually exists, but that it cannot be confirmed (without actually sending a confirmation mail)
rejects with an ` object if either the DNS lookup or the Telnet connection fails
