Utility to send an email to multiple addresses. Primarily intended for cli applications. The various fields such as server host, username, etc. are entered at the command line, used to construct a wmul_emailer.EmailSender object, and that object is passed into the main part of the script. The main part of the script can use it as needed to report errors or results without having to worry about the e-mail details.
A cli is provided for testing purposes.
class EmailSender(server_host, port, user_name, password, from_email_address=None, destination_email_addresses=None)
server_host The hostname or ip address of the smtp server.
port The port number on which the smtp server resides.
user_name The username to authenticate with the smtp server.
password The password to authenticate with the smtp server.
from_email_address=None The 'from' e-mail address.
destination_email_addresses=None The e-mail address to which the results should be sent. Must be a list or tuple for multiple addresses, or a str for a single address.
send_email(self, email_body, email_subject, from_email_address=None, destination_email_addresses=None)
email_body The body of the e-mail to be sent.
email_subject The subject line of the e-mail to be sent.
from_email_address=None The 'from' e-mail address, if provided here. If a from_email_address is not included when calling this method, the one provided to the constructor will be used.
destination_email_addresses=None The e-mail address to which the results should be sent, if provided here. If destination_email_addresses are not included when calling this method, the ones provided to the constructor will be used. Must be a list or tuple for multiple addresses, or a str for a single address.
Raises ValueError if either destination_email_addresses or from_email_address are omitted from both the constructor and the call to send_email.
A cli is provided to test that the credentials are functional and that the system can send e-mails.
send_test_email --email [email protected] --server smtp.example.com --port 25 --username myusername --password mypassword --from_address [email protected]
If everything works, then [email protected] will receive an e-mail from [email protected] with the subject Test e-mail from wmul_emailer and body This is the test e-mail from wmul_emailer.py. If you are reading this, the software is configured correctly.
