(Tcl) 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".
load ./chilkat.dll # 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. set mailman [new_CkMailMan] # Set the SMTP server. Perhaps it is the local machine. CkMailMan_put_SmtpHost $mailman "localhost" # Or perhaps it's a particular computer on the local network: CkMailMan_put_SmtpHost $mailman "192.168.1.123" # Or provide a local domain that resolves to an IP address on the local network: CkMailMan_put_SmtpHost $mailman "mymailsesrver.com" # Set the SmtpAuthMethod property = "NONE" CkMailMan_put_SmtpAuthMethod $mailman "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 set email [new_CkEmail] CkEmail_put_Subject $email "This is a test" CkEmail_put_Body $email "This is a test" CkEmail_put_From $email "Chilkat Support <support@chilkatsoft.com>" set success [CkEmail_AddTo $email "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. set success [CkMailMan_SendEmail $mailman $email] if {$success != 1} then { puts [CkMailMan_lastErrorText $mailman] delete_CkMailMan $mailman delete_CkEmail $email 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: set success [CkMailMan_CloseSmtpConnection $mailman] if {$success != 1} then { puts "Connection to SMTP server not closed cleanly." } puts "Mail Sent!" delete_CkMailMan $mailman delete_CkEmail $email |
