I am not sure how, but my IMAP folders are a mess, with duplicate and recursive nested folders. For example: INBOX.INBOX.Sent, etc. I think it might have been connecting from multiple mail clients that may not have all had the IMAP prefix set correctly.
Generally, I use Apple's Mail.app on 2-3 different computers. When accessing via webmail, I use Squirrel Mail. Here are some screenshots of what Squirrel Mail shows as the folder hierarchy.
Can anybody explain why this happened (so I can avoid it in the future)? And also what is the best way to merge and clean things up? Eventually, I want to move this account to being hosted by gmail so I can use their webmail interface, although Mail.app would be my primary email tool.
Thanks in advance.
