hi,
dovecot from the debian lenny backports does not successfully accept
incomming imap or imaps connections;
when the client connect i can see the clients ip address in an
imap-process but the client cannot succesfully connect and retries this
several times where an new imap-process is bound until the maximum
connections per client is reached;
when the client is closed the imap-processes on the server stay opened,
even when dovecot will be restarted or stopped - the processes needs to
killed manually;

i have a working installation from the stable repository with the same
settings - but i need the newer dovecot for the nfs feature;
i know there was a kernel bug prior 2.6.27 which also causes such a
problem, but i have now the 2.6.32 running and still having this problem
- no client connection could be established....
has anyone a idea or a solution for me?
thx,
alex
