Hallo Lars I'm running a mail system with about 100000 subscribers at a rate of 20 - 25 messages/sec my LDAP is iPlanet Directory Server 5.1 but there's nothing that prevents me from using OpenLDAP. Well actually the last time I tried using OpenLDAP (2.0.[1-6]) it had an extremely high iowait. We also run imap(very busy due to webmail ~ 150-200 concurrent connections) and pop3 daemons. The hardware: a single Sun Netra t1 105 440Mhz UltraSPARC-IIi 1024M RAM + two SCSI 17GB harddrives
