The 9361-8i does support passthrough ( JBOD mode ). Make sure you
have the latest firmware.

CPU for Dovecot
...n local RAID. Is there
some recommendation about CPU?
We can choose from:
- Intel Xeon E5-2620v4 - 2,1GHz at 8,0GT 20MB cache, 8core, HT, 85W, LGA2011
- Intel Xeon E5-2623v4 - 2,6GHz at 8,0GT 10MB cache, 4core, HT, 85W, LGA2011
The difference is about more cores vs. hi frequency.
Thank you, Miloslav

Postpone email delivery with LMTP and Postfix
Hi,
is there any way, based on userdb/passwdb attribute, how to postpone an
email delivery? The purpose is, I need to freeze an account (Maildir++)
for a few minutes and new email must not be delivered. But emails must
be delivered when account is unfrozen.
I found few things about Postfix filters, but I'm not sure it's a good way.
Thank you, Milo

Mailboxes on NFS or iSCSI
Hello,
we are running Dovecot (2.2.13-12~deb8u1) on Debian stable. Configured
with Mailbox++, IMAP, POP3, LMTPD, Managesieved, ACL. Mailboxes are on
local 1.2TB RAID, it's about 5310 accounts.
We are slowly getting out of space and we are considering to move
Mailboxes onto Netapp disk array with two independent network connections.
Are there some pitfalls? Not sure we should use NTP or

...created for non-existent
accounts too. We would like to prevent it.
The LDAP binding does not supporta user lookups. Is the correct way to
use checkpassword as a passdb before LDAP, check for account existency
here and:
result_success=continue
result_failure=return-fail
?
Thank you, regards, Miloslav

getcifsacl does not work with CIFS mount versions 2 or 3
Hi
When I mount CIFS share (mount -t cids) with vers=1.0 I can perform
getcifsacl sucessfully. But when I mount with vers=2.0, or 2.1, or 3.0,
ACL reading fails.
getxattr error: 95
REVISION:0x0
CONTROL:0x0
Why getcifsacl depends on SMB protocol version? Can I read ACL via newer
SMB protocol?

Migrating from Cyrus to Dovecot
Hi,
we are migrating from Cyrus 2.3.7 to Dovecot 2.2.13. We have ~7000
maildirs with ~500GB. Our goal is to do the migration without users have
notice and with the shortest service downtime. The users use IMAP (with
shared folders and ACL), POP3 and sieve filters.
As a first choice, we tried the Dovecot's dsync tool. First tests were
great, but we are not able to change the Cyrus auth
