Mailbox folders

I used to be able to see a folder marked “SENT” when I open my mailbox. It was a folder with all the messages I sent. But now when I click on the sent icon, it gives me a message: “Unable to open"Sent” and "IMAP command “SELECT” failed. What does this mean? and what do I need to do to have my sent mail show up in my SENT folder?

Why not use gmail for your DH domain mail and avoid all these issues?

Which mail client are you using? You may have to set the IMAP mailbox prefix to INBOX in your settings. In the mean time, you can use the webmail interface if you want to check you SENT folder.
