Check the existence of a mailbox via SMTP.

Project Description


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, '', '')

# 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']
