Visual Basic.NET - Send EML File

EML file is e-mail message saved by Microsoft Outlook Express or other e-mail programs; may also contain an e-mail attachment, or file sent with the message.

If you want to load EML file and edit it, you can use SmtpMail.LoadMessage method to load EML file and edit it.

If you do not want to edit the EML file, and you just need to simply forward the EML file to other recipient with 100% original data, then please see the following example codes.

The following example codes demonstrate how to load EML file and forward it to specified recipient.
