This example sends an email to bounce@chilkatsoft.com. Chilkat has setup a mailbox (bounce@chilkatsoft.com) that has a message limit of 2. The mailbox is already full, so any messages sent to it will generate an automated mailbox-full bounce reply. Chilkat is providing this mailbox so you may test your bounce handling programs.

'  The mailman object is used for sending and receiving email.
Dim mailman As New Chilkat.MailMan()

'  Any string argument automatically begins the 30-day trial.
Dim success As Boolean
success = mailman.UnlockComponent("30-day trial")
If (success <> true) Then
    MsgBox("Component unlock failed")
    Exit Sub
End If


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

'  You may test by sending email to bounce@chilkatsoft.com.
'  Chilkat created this email acccount explicitly for testing.
'  Any email sent to it will receive a "mailbox-full" bounce reply.
email.AddTo("Chilkat Bounce Testing","bounce@chilkatsoft.com")

'  Bounced email will be delivered to this address:
email.BounceAddress = "bounce.processor@chilkatsoft.com"

'  Note: the BounceAddress property equates to setting the
'  "return-path" email header.  Mail bounces are sent
'  to the email address specified in the "return-path" header
'  field, which may be different than the email address in
'  the "From" header field.

success = mailman.SendEmail(email)
If (success <> true) Then
    MsgBox(mailman.LastErrorText)
Else
    MsgBox("Mail Sent!")
End If
