similar to: Proxying pop3 sessions into an imap one.

Hi, I have problems with dovecot + ldap + nfs, we could't have more than 20 concurrent sessions of pop3, when user 21 comes, the auth process takes more than 1 sec and is incresing (while most users arrives, more delay in autenticacion exists) and my customers complaint about the service. We need support about 200 concurrents pop3 users, here is my details Front Internet 1 Load Balancer

Hi, I'm collecting users feedback of latest dovecot 1.1.rc3 development release. Some users are complaining that their sent mails sometimes don't get written to imap Sent-mail folder. It seems that all these users were using multiple istances of imap processes to read their mail (thunderbird+horde-imp, evolution+horde-imp or multiple thunderbird istances). No error message is written in

I am testing out the new Dovecot 1.2.beta1 software. I am getting reports from people using POP3 that it randomly drops connections. Looking at the log file I see that the POP3 process they were connecting to panics and dumps a Raw bactrace. Below is a copy of the logs (IP addresses striped for security): dovecot: Feb 21 13:10:45 Info: auth(default): passwd-file(janna at jantics.com,x.x.x.x):

And got this regression with dovecot-1.1.rc7 with each pop3 connection, hg version of 2 days ago was working fine. Now I'm back again to hg before "Message sort index handling rewrite".

Hi, I setup a rather large POP3/IMAP configuration and want to use dovecot proxying feature. I have noted that the capability announce when connecting via the proxies are not the same before you are authenticated and after. Before you are authenticated the proxy announce is own capability and after it announce the final server capability. The problem is that some (most ? all ?) mail client ask

Dear all, on our mail server, I let sendmail deliver incoming messages to a file in mbox format called "inbox" in each user's home directory. Now I would like to use dovecot as POP3 server so that users can let their MUA download their messages via POP3. I do not want to use any IMAP functionality. The POP3 part works with the configuration shown below, but nevertheless there is a

Hello, Just wonder: is there any way in Dovecot to limit number of active IMAP/POP3 connections for a single user, not touching any other users? Basically, the situation is single user hammering servers by lots of POP3 connections from time to time, and limiting exactly one user could be good.

I have a problem I can't seem to fix. I have dovecot configured to do POP3 with plain text authentication using a MySQL database. I am using Dovecot 1.0.7 with fcntl locking. My problem has been when an iPhone/iPod checks email. The iPhone/iPod doesn't disconnect with a TCP FIN packet and it leaves the mailbox in a locked state and prevents the user's desktop from checking

Isn't \* supposed to be (almost always) in flags after "SELECT" command in dovecot imap?

Hello, I'm preparing to convert from qpopper + UW-IMAP to dovecot. So far testing has gone very well. One problem we haven't figured out is that long-running POP sessions keep the mailbox locked, so that the MDA times out while trying to deliver. We're using "maildrop" as our MDA if that matters. We don't see this issue for dovecot IMAP sessions. During long-running

If pop3_lock_session = yes, how does Dovecot LDA handle the situation when the pop3 mbox is locked? Does it requeue mail for later delivery immediately (EX_TEMPFAIL), or wait until mbox_lock_timeout? Thanks, Ken A. Pacific.Net

I have certain power users who can't login through POP3 or IMAP from their computer while being receiving mail on their cell phones (pop3), despite pop3_lock_session = no Am I hitting some other limit? I don't see any error in dovecot.log but a generic failed login: Oct 21 10:31:44 imap-login: Info: Disconnected (auth failed, 1 attempts in 2 secs): user=<someuser at

Yes, again, some sent emails don't get copied to sent folder. This time I get the following error: Error: IMAP(username): UIDs broken with partial sync in mbox file /maildir/username/Sent This happened at least with thunderbird and with evolution. Dovecot is running on vith fcntl locking on Centos5, sendmail should use fcntl, too. Filesystem is ext3 on drbd partition. After a grep vith

I'm trying to understand what dovecot's behavior will be in a given scenario to see if it will work as a (hopefully better) replacement for the home-grown pop3 server we currently use. User A is on a slow dialup connection, and uses, oh, let's say Outlook, since that's where most of our problems seem to spring from. User A uses outlook to download his mail over pop3. Half

Hey all, A customer is configuring an offsite rsync backup. Their Internet pipe is fairly slow (DSL) but they have some very large files to backup. Their backup window is only after business hours. If one of these large files starts rsyncing at midnight, and the backup window ends before the file is complete (i.e. the rsync process stops), will it complete the rest of that file the

I'm not sure when this happened. In yesterday dovecot-1.1 hg if pop3 is compiled with DEBUG defined, it needs GDB=1 otherwise it ends with: Panic: Leaked file fd 4: dev 104.2 inode 3342766 Not sure if this can be caused by the fact that I call pop3 with a bash script. protocol pop3 { mail_executable = /usr/libexec/dovecot/pop3.sh inside I've something like if [ x`id -un` =

Hi All, Our test users re-download the mail they've left on the server when they switch from Qpopper to Dovecot. Qpopper includes the X-UIDL header - X-UIDL: X8V"!E)<"!58?"!"9C"! - on read messages. Any suggestions are appreciated. I've included my dovecot configuration. Thank you, Tristan --- Tristan Tristan Goguen CEO, ILAP? T: 416-250-5600 ext. 205 F:

With mdbox, what does dovecot lock when "pop3_lock_session(pop3): yes"? Specifically, I'm wondering if Dovecot LDA is able to deliver mail when a session is locked, if using mdbox, or if it will tempfail until the session is unlocked?

Hi, We have a serious issue running on our POP/IMAP servers these days. The load average of a servers spikes up to 400-500 as a uptime command result, for a particular time period , to be specific mostly in noon time and evening, but it last for few minutes only. We have 2 servers running dovecot 1.1.20 , in loadbanlancer, We have used KEEPLIVE (1.1.13) for loadbalacing. Server
