Close, but not quite:

LIST "" %
LSUB "" *
LIST "" INBOX/%
...

Here's an entire set of logs.  There are a few sessions here - the first one
was a successful login, but it seems it didn't fetch anything at all.  Then
there were a few other logins (some failed ones too but oddly they do NOT
show up in the logs - it's like the attemt never even hit the IMAP server).

I get the looping whenever I try to manage folders - and you know what, I
remember this being a problem on my old IMP 2.2 install - I always thought
it was an IMP bug, but maybe it's c-client with SmartMax.

Ok :)  I have no idea what's correct for IMAP aside from how to login and
logout.

That's very odd - I don't have any folders inside/below INBOX.  There's the
INBOX, and other folders along side it.  On the actual file server however,
the INBOX contains all the other folders.  Like I said though, I wouldn't be
surprised if this is a bug in SmartMax.

Not if it keeps returning something that says it's got a folder under it?
As far as I can tell, SmartMax continually replies back saying INBOX has a
sub folder or whatever...

> So anyway what really does LIST "" % return?

0 LIST "" %
* LIST () "/" "Trash"
* LIST () "/" "Sent"
* LIST () "/" "Junk E-mail"
* LIST () "/" "Drafts"
* LIST () "/" "Sent Items"
* LIST (\NoInferiors) NIL INBOX
0 OK LIST completed.
0 LIST "" INBOX/%
* LIST (\NoInferiors) NIL INBOX
0 OK LIST completed.
0 LIST "" Trash/%
* LIST (\NoInferiors) NIL INBOX
0 OK LIST completed.
0 LIST "" Drafts/%
* LIST (\NoInferiors) NIL INBOX
0 OK LIST completed.

Is that weird?  I would *think* so - no I dea why it advertises the INBOX
when I'm asking about other folders... but I don't know IMAP that well :)

If you have any more ideas, shoot them to me.  In the mean time, I am
thinking *maybe* this has something to do with SSL support in c-client
possibly.  I am going to compile a new c-client without SSL support, and
compile a new PHP and see how that fairs.  I know SmartMax IMAP doesn't do
SSL, and a connection type of "imap" or "imap/notls" both seem to work fine,
but the fact that some login attempts don't even get recorded make me think
that maybe c-client is having problems talking to SmartMax due to SSL
negotiations.
