downloading new folders

I have several subfolders off my Comcast email, there were not created when I setup eM, and I created them manually but they do not sync, the olny email downloaded is from my parent Inbox folder. Saw a post about  going to Tools > Accounts > Your account > IMAP (Mail) tab and enable the download messages for offline use option, but there was no IMAP tab and my email is POP3. Please help? Thanks, Jonathan

I have got a similar problem. It seems there is only one level of subfolders synced…
If that is the case eM Client is not for me. I have a huge set of folders in folders…
