Best Practises for vpopmail scaling

[Paul Tan]

Hi,        I have qmail/vpopmail/etc.... running on a Sun 2.8 Server. and would like to scale it to 2 servers. I understand that most cost effective solution would to go for NFS. Are there any tips and tricks i should look out for when implementing vpopmail Maildirs via NFS? Am i supposed to share out ~/vpopmail/domains dir on the NFS server?? Or are there other ways of implementing it?   Thks Paul
