Steps to reproduce: 1) send an e-mail from YOURSEMAIL@post.com to THEIRSEMAIL@post.com 2) go to "sent" directory in your directories tree 3) LMB in your messages list on the e-mail you've sent 4) LMB on "Reply" in the toolbar 5) A window to compose a message will appear 6) LMB on "Send" in the toolbar Behaviour: The application doesn't show a warning that your "From:" and "To:" field is set to YOURSEMAIL@post.com Expected behaviour: The application could show a warning that your "From:" and "To:" field is set to YOURSEMAIL@post.com and in the effect you're sending a message to yourself and nobody else.
Here I get the expected result, clicking on a mail such as you have described, the To in the reply is the same as the To in the original mail. This works as long as the original "From" address matches one of your accounts' addresses. Are you seeing something different?
Ok, it works for "sent" directory but not if I try to replay from a normal directory.
I can't even get such warning when replying to myself from a message in Sent folder. I think I've never seen such warning at all (but replied to myself from time to time).
To clarify, I don't get any warning neither. When I said that it works I meant that "To" field is preset as expected when replying from "Sent" directory and set not as expected when replying from my custom directory.
