There was a case during the Oneiric cycle where this issue came up again. You can work around this by setting the Sent folder for that account again in the accounts' settings, under "Default Settings".

Recent oneiric upgrades broke this and I get the following error whenever I send an email: 'Message was sent, but an error occurred during post-processing. ...Failed to append to imap:///....Sent: Cannot get folder 'Sent': folder does not exist. Appending to local 'Sent' folder instead.' This can easily be fixed by going to Edit/Preferences/Mail Accounts then selecting the account, click Edit, and going to the Defaults tab. Looking at the entries for Drafts and Sent, I only see 'click here to select a folder' rather than the folder I used to have prior to upgrades. I'm assuming this is some sort of migration failure.
