Hello, I sent this into the Linux Kernel Btrfs mailing list and I got reply: "RAID-1 would be preferable" (https://lore.kernel.org/linux-btrfs/7b364356-7041-7d18-bd77-f60e0e2e2112 at lechevalier.se/T/). May I ask you for the comments as from people around the Dovecot? We are using btrfs RAID-10 (/data, 4.7TB) on a physical Supermicro server with Intel(R) Xeon(R) CPU E5-2620 v4 @

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

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

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? A asked on Serverfault but without reply:

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 here and: result_success=continue

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

I cannot verify it, but I think that even JBOD is propagated as a virtual device. If you create JBOD from 3 different disks, low level parameters may differ. And probably old firmware is the reason we used RAID-0 two or three years before. Thank you for the ideas. Kind regards Milo Dne 10.09.2020 v 16:15 Scott Q. napsal(a): > Actually there is, filesystems like ZFS/BTRFS prefer to see

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. I'll try to move

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.

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

Hi James, I tested (as I wrote a few days ago) the latest PV drivers release, and they seem to work correctly apart of the "Safely remove Xen Net Device Driver" tray icon glitch. I made a series of benchmarks with PassMark''s PerformanceTest on 6 twin concurrent VMs with the PV drivers installed, both with the /GPLPV switch on and off, and on one lonely VM, still in both

Obviously not a very fair comparison [1]. I can''t see how this was done well at all. VMWare are a bit silly to release stuff like this, just lowers the whole game.

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] and it
