User Agent: Mozilla/5.0 (Windows NT 5.1; rv:13.0) Gecko/20100101 Firefox/13.0.1 Build ID: 20120614114901 Steps to reproduce: I have modified a draft saved on IMAP server by my colleague. Actual results: When I tried to modify the draft, the outgoing e-mail address was automatically changed to another e-mail address - there are more accounts in my Thunderbird. In other words - Thunderbird has forgotten the account, where the draft was saved and chose another (the first, random or last used account from my account list?). Expected results: The outgoing e-mail address had to stay the same, as my colleague has saved - according to the account where the draft has been saved.

(In reply to zdenek from comment #0) Your colleague saved the draft initially using his account? And then you used it to save it as your account? If that is the case, I think it is logical for Thunderbird to change the sender.

My colleague has created an e-mail and saved it into Drafts for my review. I opened it, checked the text (unfortunately not the sender e-mail address) and after that I sent it. But Thunderbid changed the sender address to another. I think, that is very unexpected feature, there is no reason to change the sender address.

Closing as dup of bug 279846, per comment #4.
