I have started with K9Mail only a few days ago, therefore I am still searching for sone settings. One of them is, I have created two different identities, but I do not know how to choose the requested one when I am writing a mail.
Anyone here who could help me out?
Thank you in advance.
If a matching identity exists in the account, it should be used automatically in replies.
When composing new messages you can press and hold the From address field to view a list of available identities.
Last thing before going to bed, I tried according to your reply, and what can I say, it works just the way that you described. Therefore, thank you very much for your assistance!
