Version: (using KDE 4.3.1) OS: Linux Installed from: Gentoo Packages When I do right-click->"Send Again" in my sent-mail folder, kmail does not retain the From-adress and also ignores the signature state (signing on/off). If I select "Send Again", I expect kmail to retain the exact same mail I had before (and I'm pretty sure this worked in kde 3, I don't have one installed to test, but I assume it's a regression).
I tested now various combinations (From addresses, signed/unsigned mails) - all work as expected. Are you using POP or IMAP ?
I'm using POP3, although this is about mail-sending, which is obviously SMTP. Step-by-step to reproduce: Create a mail with an identity that has signing as default, change the From adress to something != the identitys default. Select the mail in the sent-folder, right-click->"Send again", it has the identitys default mail adress and signed selected on. This is different for you? I can try producing a desktop-recording to show the behaviour.
Even though this is about sending, I thought the sent mail is stored somewhere, and this might be locally or on an IMAP server (but as I have no knowledge about IMAP, I might be wrong). Ok, so the problem comes from the fact that you change manually the From address. With that, I can reproduce your description. But you mention the signed/unsigned setting in your first posting, which is preserved in my case and you say in your last comment that it's also ok for you. So it seems the problem you describe is only with the "From" address, right? However, I'm not sure if that is a bug. One could say I want to open the composer with the identity I selected the first time I created the mail. In fact kmail stores a special header inside the sent mail to know with which identity it was sent (X-KMail-Identity) Also, I'm not sure why you select one identity and then change the From address manually. Isn't that exactly the reason why we have different identities, to be able to define different From addresses beforehand ?
Hello! Sorry to be the bearer of bad news, but this version of Kmail has been unmaintained for many years so I am closing this bug. Please try using the latest version of Kmail to see if your issue persists. If it does, please submit a new bug in "kmail2". Thank you!
