Hello,

what do you think about moving the mailspool to a central SAN storage 
shared via NFS and having several blades to manage the mmapped files 
like seen state, quota etc.? So still only one server is responsible for 
a certain set of mailboxes, but these SAN boxes have nice backup and 
redundancy features which are hard to get with common servers and there 
shouldn't be mmap problems as long as all indices remain on the blade on 
a separate metadata-partition.

Regards
Marten
