I have a problem, I am in DreamHost, and the emClient works nice, it’s the better email client I have had, but it give me continuous errors like this:
[email protected]: An error ocurred
[IMAP] Unable to create folder “[email protected]/Trash/” on the server
(Unknown namespace.)
An when I restart emClient all folders are empty…
Please help me I don’t want to use Thunderbird, I want emClient!
Thanks to all 

Nobody helps me? There’s someone out there!?
Try changing your id from [email protected] to something other than an email address. The account setup will still have the email address, but rename the ID for example:
[email protected] changed to jack … folder create errors go away.
In your case, [email protected] might become ContactYouTo
I had the same problems with Dreamhosts.
Worked for me! Thanks a lot Mark!
