We suffered the same problem and came to the same conclusion. Courier
had to go. We installed Binc two years ago and have been very happy so
far. I doesn't even use enough resources to know it is there, I honestly

We looked at Dovecot and may again, but we choose Binc because we needed
maildir++ quota support (which Dovecot now supports).
