Check the existence of a mailbox via SMTP.
This package exists to help poll smtp servers to see if a mailbox address is valid. It doesn’t return true or false, but a set of status codes, extended status codes, and full messages from the responding server.
Here is an example using pyDNS as the MX resolver:
from check_email_status import check_email_status from check_email_status.resolvers import PyDNSMXResolver status = check_email_status(PyDNSMXResolver, 'firstname.lastname@example.org', 'email@example.com') # This is the SMTP status code returned by the server. (e.g.) 550 print status['status'] # This is the extended status code, for instance 5.1.1 would mean the account doesn't exist. # If an extended code is not sent, this is not set. print status['extended_status'] # This is the message returned from the mail server describing the results of the query. print status['messsage']
