At my previous job we changed from exim/uw-imap on mbox, to exim/docevot on maildir a couple of years ago. Didn't use a cluster-fs, only SCSI-based disk failover. For about 500-users. Right now I'm setting up a similar solution to your... trying to support up to 200.000 users on a 5 node cluster, using IBM GPFS. If sendmail is using procmail to do final mailbox-delivery, I think the configuration change should be primarily putting a '/' at the end of the path, as that should instruct procmail to do maildir-style delivery. At least that's how I've been doing it in my ~/.procmailrc. Ref. 'man procmailrc'. > i have 3000+ users and something like 70GB of > emails and I'll have to test it very well before doing in the > production server .... Sure.. There are a few mbox2maildir converters.. You should probably try a few of them and verify that they all give the same result. Another thing to check is that your cluster-fs handles your load well. My main consern would be how well GFS performs on maildir-style folders, as most cluster-fs's I've seen are optimized for large file streaming I/O. If possible, try to keep a lot of file-metadata in cache so that you don't have to go to disk every time someone check their maildir for new messages. -jf -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
