From Dovecot's side the only thing you can do is fsync_disable=yes.
The main problem is probably network latency, because Outlook
doesn't support MULTIAPPEND extension (and perhaps not even LITERAL
+ extension?) Did you already try running Dovecot on the same
computer as Outlook (some virtual thingy or maybe it works in
cygwin)?
I just tried fsync_disable=yes but with NFS and had to turn off
mail_nfs_index = yes as well but the speed was the same. Do you
think it would be different with a UFS or ZFS backend with
fsync_disable?
Could be. NFS clients typically wait for NFS server to reply to writes
before continuing. I think it "async" mount option might disable that,
but I'm not sure.
