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".

    // This example requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    Set ComSmtpHost Of hoMailman To "localhost"
    // Or perhaps it's a particular computer on the local network:
    Set ComSmtpHost Of hoMailman To "192.168.1.123"
    // Or provide a local domain that resolves to an IP address on the local network:
    Set ComSmtpHost Of hoMailman To "mymailsesrver.com"

    Set ComSmtpAuthMethod Of hoMailman To "NONE"

    // 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:
    Get ComCloseSmtpConnection Of hoMailman To iSuccess
