Well ... I apologize !

I finally found the problem but it sounds a bit strange

I had to increase the  max_mail_processes to 8192
to have a functionnal IMAP server with normal clients AND
squirrelmail clients

8192 sounds enormous to me , any infos welcome !

the machine run Debian etch 64 bits , dovecot has been
re-compiled on the machine. it is an IBM X3650 with 7Gb of RAM.
