We have a linux IMAP server that uses “Sent” as the default name for it’s Sent Items folder. However, at least in my case, the OS X Mail app seemed to expect the folder to be called “Sent Items”.
To set the Sent folder to be pointed at the correct Sent Items folder, you must select that folder from the account tree, and then select Mailbox > Use This Mailbox For > Sent.
It took me a while to work this out, so I have posted here for future reference.
thanks a lot, that was what I was looking for!
Thank you! You saved my afternoon. It seems Mail will not fully cooperate (in terms of Sent, Drafts, and Junk) with IMAP server settings unless the technique above is followed. I’ve been trying to control Mail from the wrong end all this time…
