Xojo Plugin for Windows, Linux, Mac OS X, and ARM, ARM64

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

Dim mailman As New Chilkat.MailMan

mailman.SmtpHost = "smtp.my-mail-server.com"
mailman.SmtpUsername = "MY_SMTP_USERNAME"
mailman.SmtpPassword = "MY_SMTP_PASSWORD"

Dim success As Boolean
success = email.AddTo("Chilkat Admin","admin@chilkatsoft.com")
// To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

// Add some attachments.
// The AddFileAttachment method returns the value of the content-type it chose for the attachment.
Dim contentType As String
contentType = email.AddFileAttachment("qa_data/jpg/starfish.jpg")
If (email.LastMethodSuccess <> True) Then
    System.DebugLog(email.LastErrorText)

End If

// We see the following in the e1.eml
// Notice that Chilkat replaced the full path with just the filename.
// The full local path is not part of the email that gets sent..

// ...
// --------------020807050607070004010609
// Content-Type: image/jpeg; name="starfish.jpg"
// Content-Transfer-Encoding: base64
// Content-Disposition: attachment; filename="starfish.jpg"
// 
// ...

// Content-Type: application/pdf; name="fishing.pdf"
// Content-Transfer-Encoding: base64
// Content-Disposition: attachment; filename="fishing.pdf"
// ...

// Before sending, each filename can be changed within the email object.
// For example:
success = email.SetAttachmentFilename(0,"orange_starfish.jpg")

// ...
// --------------020807050607070004010609
// Content-Type: image/jpeg; name="orange_starfish.jpg"
// Content-Transfer-Encoding: base64

// Content-Type: application/pdf; name="tuna_fishing.pdf"
