// 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.
Dim mailman As New Chilkat.MailMan

// To use a SOCKS4 or SOCKS5 proxy, simply set the following
// properties prior to making any calls that communicate with
// an SMTP server:
// The SOCKS hostname may be a domain name or 
// IP address:
mailman.SocksHostname = "www.mysocksproxyserver.com"
mailman.SocksPort = 1080
mailman.SocksUsername = "myProxyLogin"
mailman.SocksPassword = "myProxyPassword"
// Set the SOCKS version to 4 or 5 based on the version
// of the SOCKS proxy server:
mailman.SocksVersion = 5
// Note: SOCKS4 servers only support usernames without passwords.
// SOCKS5 servers support full login/password authentication.

// Set the SMTP server.
mailman.SmtpHost = "smtp.chilkatsoft.com"

// Set the SMTP login/password (if required)
mailman.SmtpUsername = "myUsername"
mailman.SmtpPassword = "myPassword"

// Create a new email object
Dim email As New Chilkat.Email

email.Subject = "This is a test"
email.Body = "This is a test"
email.From = "Chilkat Support <support@chilkatsoft.com>"
Dim success As Boolean
success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com")

// 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) Then
    System.DebugLog(mailman.LastErrorText)
    Return
End If

// 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) Then
    System.DebugLog("Connection to SMTP server not closed cleanly.")
End If

System.DebugLog("Mail Sent!")
