You can put the messages on hold and then release them

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

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

Btrfs RAID-10 performance
Hello,
I sent this into the Linux Kernel Btrfs mailing list and I got reply:

May I ask you for the comments as from people around the Dovecot?

Userdb by directory lookup
One day, I'll use the LDAP. But infrastructure I got is quite neglected
and some older admins is hard to convince to innovate. Just, aaaaah :)
I read whole documentation related to userdb a and passdb. Easy to
understand with relation to IMAP or POP3 access. But what I didn't
understand is relation to LMTP. Which one is used and when for
successful delivery.

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?

Btrfs RAID-10 performance
Some controllers has direct option "pass through to OS" for a drive,
that's what I meant. I can't recall why we have chosen RAID-0 instead of
JBOD, there was some reason, but I hope there is no difference with
single drive.
Thank you

CPU for Dovecot
Hi,
we are planning to change hardware for our standalone Dovecot instance
handling ~5800 IMAP users with 1TB mailboxes on 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

Userdb by directory lookup
Hi,
I have the Dovecot (2.2.27-3+deb9u2) with LMTP and Postfix. Static userdb:
userdb {
driver = static
args = uid=vmail gid=vmail home=/data/vmail/user/%n allow_all_users=yes
}
and passdb by LDAP, only to verify IMAP user password by bind.
Problem is, when someone sends email to non-existent at mydomain.tld,
Dovecot automatically creates its home directory and Maildir.
Is there any

Renewal of Let's Encrypt Certificates in Dovecot
Hi there. I've been using Dovecot for quite some time now but I just
started using Let's Encrypt certs. Since LE certs are renewed automatically
without user intervention I'm wondering if I will need to restart dovecot
after that renewal...
Has anybody had any experience with that?
Thanks so much for your help!

Hi,
we have one user using the old Alpine client with IMAP. Time to time (3
times per day or 3 times per week) he get error: "MAIL FOLDER INBOX
CLOSED DUE TO ACCESS ERROR" and he complains, that inbox stops to
refresh with new emails.
I don't know Alpine but I can imagine, that Alpine creates TCP
connection to IMAPS and uses IDLE. I read wiki page about Timeouts [1]

Allow delivery to existing accounts only with LDAP and static
Hi,
we are using LDAP binding as a passdb, and static with
allow_all_users=yes as an userdb.
Works fine, but problem is, Maildirs are 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

a few questions about ext3 journal
A few wild ideas/questions :
1) Is there a way to check the size of the journal of an ext3 filesystem ?
I mean - the actually used size ; not the total size of the journal.
2) Would it be difficult to implement "freeze" of ext3 filesystem - that
is, blocking all I/O to the filesystem until it's "unfrozen" (XFS can do
that), for two purposes :
