I agree of course about avoiding SPOFs, but I do like a multi-tiered
approach, I mean multiple lines of defense. I use SAN for its speed,
reliability, and ease of administration, but naturally I replicate
everything on the SAN and have "true" backups as well.
So you have multiple SAN's? Or y
GSSAPI authentication from Thunderbird to Cyrus IMAP works!
You MUST:
1. Specify a FQDN for your IMAP server in Thunderbird's
account settings. I was specifying an IP address. Not
good enough.
2. The FQDN must resolve somehow. For me, it was a matter
of adding info to C:\WINDOW

Fastmail dont use SAN, as I understand they use external raid arrays.
There are many ways to lose your data, one of these being filesystem
error, others being software bugs and human error. Block-level replication
(typically used in SANs) is very fast and uses few resources but doesnt

NFS does not work with cyrus. Been there, done that, didn't like

The whole point of a SAN is distributed access to storage after all :).
SAN distributes the disk, not the filesystem. I presume in this case hes
not using the SAN for its multiple-client-access features but just
because its fast/reliable.

Fair enough, although NFS is likely to be really rather slow compared to a

Hi everyone,
I have a user running Outlook 2000 and new messages stopped showing a few
days ago. After running reconstruct once, two new messages showed up, but
subsequent runs have not had any affect.
I have about 50 users running a mix of various Outlooks, Thunderbird and
