What options are available for remote storage, i.e. storage devices directly mounted on the machine running Dovecot? I've seen discussions of NFS usage - but my experiences with NFS in times past have been poor. CIFS has worked well for me for non-mail use - would this be suitable? Or is there another method I've not considered? I'm actually trying it - and at first glance it's functional. I'm using

I'm using Dovecot 1.1.11 (from Ubuntu Jaunty). Also Postfix, LDAP, and a few other odds & ends. While message delivery is working (using deliver), I do see the following in my logs:

That error from deliver with "fdatasync_path" bothers me - what does that indicate, and where should I go to fix it? Based on mmap errors, I already set "mmap_disable = yes"
