I have approximately 10 accounts and from time to time it happens, that I compose a mail while I am in the wrong inbox. I also forget to choose/change the outgoing mailserver explicitely. So the mail will be sent from the wrong account. As I want to keep my mail accounts apart from each other, is there an option, which always asks me to choose an outgoing server before sending? Or can I deactivate that an outgoing server is chosen by default forcing me to choose it manually?
