Thank you for your valuable input, it sounds very interesting. I'm quite
happy that no one considers running several exim-server with a shared
filesystem to be a major problem, but currently I stopped optimizing
exim and try to run an IMAP-server on the same filesystem.
As I feared, that task proves to be much more difficult. Usually we are
running Cyrus, but it doesn't like mmap with the special file-system. :-(
Website says "we do mmap". Support-staff says "no, we don't". Referring
support-staff to website causes confusion. ;-) Issue unresolved for two
days, they usually perform better...
But I'm getting off-topic...
