How to send programmatically an email from another mail client than outlook or outlook express?

From within your application you can send an email by using MAPI functions ("MAPISendMail"). But if there is another mail client installed like "Thunderbird" or "David InfoCenter" the use of MAPI functions does not work, because "Outlook" or "Outlook Express"开发者_JAVA百科 is not the standard email client.

The use of shell functions to execute "mailto:" is not satisfying because not all email clients do support command line parameters for mail attachment or mail body.

What can I do instead to get my desired result?

Which platform?

If .NET take a look at this the SmtpClient class.
