Can't create and send mail [answered]

Thank you very much, it doesn't work, but so I got the idea to setup a second mail account. After that, I can select one of these accounts as default. I thought, that the default account for sending would set automatically, when there is only one account, but it seems, that this won't work.

Thank you for your support :-)

You're welcome. Hope it works out now.

Thanks, yes all works fine now.

I have an additional hint. After setting up an other mail account and set my main account to default, I deleted the second account and the 'Create Mail' function is still active. It's a helpful workaround.
