is there any difference btwn cyrus-imapd-2.2.12-5 and cyrus-imapd-2.2.12-27.6 ?

[JOYDEEP]

OK list,

I have a doubt here and requesting you to guide me.

I have one suse 10.1 box with cyrus-imapd-2.2.12-27.6  and one suse9.2
box with cyrus-imapd-2.2.12-5 .
both the cyrus installation have the same configuration.

but in cyrus-imapd-2.2.12-27.6  imap folders are created like 
/user/<username>   /user/<username>/<inbox>
but in cyrus-imapd-2.2.12-5        imap folders are created like 
user.<username>    user.<username>.<inbox>

unixhierchysep:  yse   is set in both the cyrus configuration.

Sieve is working with cyrus-imapd-2.2.12-27.6 but not with
cyrus-imapd-2.2.12-5

So is there any bug in cyrus-imapd-2.2.12-5 ?

thanks
