I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options?

Hello, is it possible to limit the number of pop3 (or imap) login attempts from one IP with dovecot to stop attackers? We recently had an attack from one IP-address lasting 50 minutes that tried 50000 pop3-logins with guessed users and passwords. I know about Fail2Ban but really would prefer an easy to configure solution inside of dovecot. Dovecot has this anvil daemon, can it be used

Hi, I was unclear in my question. The spam filter is only able to deliver mail over SMTP, not over LMTP.. So I would still need some kind of daemon that listens for SMTP and then offers incoming email to Dovecot's LMTP socket.

Hi, I have a fedora28 system with dovecot-2.3.5 and I'm trying to figure out why I'm increasingly receiving duplicate emails. The message IDs are exactly the same. It's always two of the same messages. I don't think it's ever occurred in the inbox. It doesn't happen with every message or seemingly in every folder. I've read about dovecot deduplicate, but of course I

Hi. I'm setting up a new IMAPS server. Mail users don't have login access to the box but will each have unique UNIX-style UIDs: no back-end database or LDAP thing. So far. Their mail will get delivered to UNIX-style mailboxes in /var/mail/%u (where %u is the UNIX username obviously). Their IMAP folders will go in /var/imap/%u. These will contain subfolders once everyone migrates to the new

Here's a few tips: 1. I assume that's a 2U format -24 bays.?You only have 1 raid card for all 24 disks ? Granted you only have 16, but usually you should assign 1 card per 8 drives. In our standard 2U chassis we have 3 hba's per 8 drives. Your backplane should support that. 2. Add more drives 3. Get a pci nvme ssd card and move the indexes/control/sieve files there.? On Monday,
