no we used to stop dovecot and killall imap what for the low load and
restart dovecot manually. after we do it for an hour the load goes back
to "just" 2-3 and in this case yes courier is much faster that dovecot.

which imap process? since even if I set the maximum imap connection in 
mozilla to 1 logout and login again the mozilla (or dovecot) change it 
back to at least 2:-(
anyway I try all of them, both as root and as the user itself, the only 
result is:
trace: ptrace(PTRACE_SYSCALL, ...): Operation not permitted

any other logging mode?
