You shouldnt need to do that. Are the mailboxes on UFS ? If so, try
increasing


vfs.ufs.dirhash_maxmem


Also, if you have a lot of users in the master.passwd file, I find
changing /etc/nsswitch.conf to

group: files
group_compat: nis
hosts: files dns
networks: files
passwd: files
passwd_compat: nis
shells: files
services: compat
services_compat: nis
protocols: files
rpc: files
