I am unable to manage / sync my Smartermail mailbox using IMAP from my Galaxy S II Skyrocket. Same results whether using ssl or not. IMAP doesn't seem to be the issue, as I can connect to gmail IMAP without any issues. I've done quite a bit of trouble shooting including working with my hosting company as well as with at&t. It wasn't until I switched to POP that I was able to see my mailbox.
