Wrong sender when sending email through windows app (sender same than receiver)

Dear all,

We got a windows application that allows user to send directly emails from within the app using the default email client.

For some reason with Outlook this feature works correctly, but if I do use the same function thought Thunderbird, the email is send but with the wrong sender, instead of using my email account as sender, Thunderbird uses the receiver address as sender too.

Any ideas on how to fix this will be really appreciated.

Thanks, Javier.

Is the app designed to work with Thunderbird? Are there settings you can change within the app? I assume that the app invokes the email client, passing to it the address of the sender, the address of the receiver and the content of the message: if those data are wrong, then the email client will not behave as you want.

Thanks for your quick response.

The app has no settings you can modify, it seems to be designed to work with the default email client, it can be thunderbird, outlook or others.

I know its not very helpful, but with outlook it does work OK.

Thanks, Javier.

What does this mail look like in the sent folder?

Hi Matt,

You can see my attached screenshot.

It looks just like any other email, except for the wrong sender.

Thanks, Javier.

Thunderbird has a very particular formulation for use with another program.

See http://kb.mozillazine.org/Command_line_arguments_%28Thunderbird%29

If your other program doesn't know this, and if it doesn't invite you to tell it which mail program you're using, or allow you to adjust it, then it's probably a non-starter.

Outlook was designed to work with other Office components (Word, Excel etc) and so has an interface that allows these and other programs to communicate with it. Your program probably takes advantage of this feature.
