Hello,
I have recently changed imap from Courier-imap to dovecot because of
serial problems with courier-imap, I have being forced to do it very
quickly... and without extensives tests.
I have 3 mails servers (freebsd based) behind a load balancer and a
nfs mailstore on a netapp.
On my first tests I have setup the index into some nfs shared mount,
but it seems that some imap clients are going mad when deleting files
(mostly because they do open some new imap connection and the index
was not clean) so I have changed index to memory.
This has fixed one of my problems.
Now I have some strange problems is that NFS activity passed from
about... 5mbps to more than 70Mpbs...
Is there any reasons about that ?
OS: FreeBSD 6.2-p11 / x86
Dovecot : 1.0.13 (freebsd ports)
Auth: ldap based
Nfs mail spool :
filer:/vol/vol0/mail /var/mailusers nfs
rw,nfsv3,mntudp,bg,noatime,nolockd 0 0
Thanks,
/Xavier
