(Chilkat2-Python) Send Email without Authentication (no Login)Demonstrates how to send email using an SMTP server that does not require authentication. An SMTP server that needs no authentication should be protected by a firewall, to prevent outsiders from using it as a SPAM server. To send email without logging in, simply set the mailman's SmtpAuthMethod property = "NONE".
import sys import chilkat2 # This example requires the Chilkat API to have been previously unlocked. # See Global Unlock Sample for sample code. # The mailman object is used for sending and receiving email. mailman = chilkat2.MailMan() # Set the SMTP server. Perhaps it is the local machine. mailman.SmtpHost = "localhost" # Or perhaps it's a particular computer on the local network: mailman.SmtpHost = "192.168.1.123" # Or provide a local domain that resolves to an IP address on the local network: mailman.SmtpHost = "mymailsesrver.com" # Set the SmtpAuthMethod property = "NONE" mailman.SmtpAuthMethod = "NONE" # Set the SMTP login/password (this may be omitted given no authentication will take place) # mailman.SmtpUsername = "myUsername"; # mailman.SmtpPassword = "myPassword"; # Create a new email object email = chilkat2.Email() email.Subject = "This is a test" email.Body = "This is a test" email.From = "Chilkat Support <support@chilkatsoft.com>" success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com") # To add more recipients, call AddTo, AddCC, or AddBcc once per recipient. # Call SendEmail to connect to the SMTP server and send. # The connection (i.e. session) to the SMTP server remains # open so that subsequent SendEmail calls may use the # same connection. success = mailman.SendEmail(email) if (success != True): print(mailman.LastErrorText) sys.exit() # Some SMTP servers do not actually send the email until # the connection is closed. In these cases, it is necessary to # call CloseSmtpConnection for the mail to be sent. # Most SMTP servers send the email immediately, and it is # not required to close the connection. We'll close it here # for the example: success = mailman.CloseSmtpConnection() if (success != True): print("Connection to SMTP server not closed cleanly.") print("Mail Sent!") |
