Could you please example of both the contacts, one which works and other one which doesn't work and what do you mean by respond ?

oh sorry my english is so bad.. now i changed my system to english and now i saw that its reply..

so, i have 2 accounts in evolution (one imap with smtp and one just smtp) and i get all my mails forwarded to the imap-account. when i click reply it has automaticaly the standart-adress as my responding-adress doesn't matter if the mail was sended to account a or account b. maybe its because all the mails are forwarded to account a?! a third account (imap and smtp) no has this problems.. when i am responding one of these mails it knows to reply with the adress c.

i know it was working in the version which was part of ubuntu 9.04.

I have the same problem with Evolution 2.28.1

I am using IMAP on my server. This server loads all my emails via POP3 to the IMAP storage. 
My default account (default@mail.com) in Evolution had configured this IMAP server in the "Receiving Email" tab. My server isn't an SMTP server so I have configure another SMTP server in the "Sending Email" tab.
Then I have another account (another@mail.com) in Evolution with a Server Type "None" in the "Receiving Email" tab and the same SMTP server as my default account but with the other email. (I am using a few aliases for my email account)

If I receiving an email to another@mail.com and reply to this mail the FROM in the Evolution composing window is always default@mail.com instead of another@mail.com

But I would like to reply with the same address the email was sent to.

Hope the problem is clear now and I think this behaviour is easy reproducible on every system!
