Quoting CJ Keist cj.keist@colostate.edu:
I'm working on bring up a new mail server to replace our current
one. Our current mail server is running dovecot 1.1.16, with
postfix using mbox format. User inboxes are stored locally on the
mail server and all other mail folders in users home directory under
mail which is NFS mounted on the mail server.For our new mail server I'm looking to switch to the Maildir format.
Some years ago I remember reading that it was not recommended to
run Maildir format over NFS. Now I'm looking at several posts that
seem to indicate that Maildir should run fine over NFS. I'm a
little concerned about running Maildir over NFS, especially from the
howto conversion pages I read would move all messages over to the
User ~/Maildir folder including the inbox. So having every single
mail transaction going over NFS doesn't seem the smart thing to do.So question I have for the dovecot team, does running Maildir over
NFS work well? Or would you recommend that all user mail folders be
stored locally on the mail server when using Maildir?We have about 3400 users, doing about 30k mail deliveries daily.
Some users have 10's of thousands of mail messages in hundreds of
mail folders.
I'm happy with maildir on nfs (netapp), doing 3million receiving per day.
Looking at the new methods for v2.0, still on the fence though with them.
