Your system is plenty powerful - no issues there.
What are your settings in the init script? I found that putting in a
ulimit -n 8192 and ulimit -f 16384 prior to invoking dovecot was
worthwhile on my system.
I would first try tweaking these settings in a root shell and then
invoke dovecot with a -c conf make sure it is picking up the right conf
I'm sure the list will ask for the dovecot -n -c ... output as well.
