dovecot - Jan 2012 - migrate dovecot files 1.2.16 to 2.0.13 (OpenBSD 5.0)

Hi, 

I have a mailserver(Postfix+MySql) on OpenBSD 4.9 with Dovecot
1.2.16, all works fine.
Now i want to do the same but on OpenBSD 5.0.
I
meet problems using dovecot 2.0.13 on OpenBSD 5.0. 

Some tests (on the
box):

telnet 127.0.0.1 110
Trying 127.0.0.1...
Connected to
127.0.0.1.
Escape character is '^]'.
Connection closed by foreign
host.

telnet 127.0.0.1 143
Trying 127.0.0.1...
Connected to
127.0.0.1.
Escape character is '^]'.
Connection closed by foreign
host.

Seems that pop3/imap doesn't work 

'netstat -anf inet'
tcp 0 0
*.993 *.* LISTEN
tcp 0 0 *.143 *.* LISTEN
tcp 0 0 *.995 *.* LISTEN
tcp 0 0
*.110 *.* LISTEN

Therefore, ports are open. 

When i use Roundcube
webmail, i have errors : error imap connection 

If someone can help me on.
Thank you very much.

Files to migrate (already tried to modify them) :
dovecot.conf / dovecot-sql.conf / and 'dovecot -n '
