[Dovecot] Authentication and Startup/Shutdown error.
by Andrew Lietzow 28 Aug '04

28 Aug '04

Hello and ... help! I am using Redhat FC2. I was looking for a simple POP3 compatible application package that would allow growth into secure mailboxes, and it looks like dovecot can fill the bill, and then some. I am a newbie. I scanned the Wiki but am as confused by it as I am by my problems. Fortunately for me, I don't need 7 different authentication schemes; I just need something simple that works with Thunderbird and Outlook Express. Is there a HOW-TO around that shows simple pop3 setup on Linux? #1) I had the pop3-login working for a bit, but now it has stopping starting up. When I attempt a <./dovecot stop>, I get a message that the stop has [FAILED]. I believe this is because it is leaving a lock in the /var/lock/subsys directory. I delete that file and try again, same problem. The system starts okay, but there are no longer any pop3-login processes being started up. <ps -elf | egrep pop3*> returns nothing but the grep process. #2) I need a simple method to access email. Nothing fancy as I only have a couple of users. Terrorists woud be wasting their time to monkey with my server. In the dovecot.conf file, here are a few of my settings. pop3_executable = /usr/libexec/dovecot/pop3 pop3_process_size = 256 auth = passwd auth_mechanisms = plain auth_realms = auth_default_realm = auth_userdb = passwd: /etc/passwd auth_passdb = passwd: /etc/passwd auth_executable = /usr/libexec/dovecot/dovecot-auth auth_process_size = 256 auth_user = root auth_count = 2 Any help would be greatly appreciated, of course. I'll keep scanning the web site while I am at your mercy.

[Dovecot] 1.0-test37
by Timo Sirainen 28 Aug '04

28 Aug '04

http://dovecot.org/test/ - Added mbox_dirty_syncs setting, defaulting to yes. This means that while mbox is opened and new mails come, it only reads the new mails instead of the whole mbox. Then there's several checks that make sure this is safe to do and if something doesn't look right it fallbacks to syncing the whole mbox again. - dovecot-auth was leaking memory (not same bug as with 0.99/ldap) - Some other fixes

http://dovecot.org/test/ Fixes mostly. Seems to be working quite well with me nowadays with mboxes. If you see any crashes or other problems please report.

Tim, Thanks for the reply. I did check the maillog quite a bit. Fortunately, I had kept an orig of the dovecot.conf file so I rolled back to the example I found on the dovecot.org website and now it's up and running. It's all smoke and mirrors to me, mostly, but at least it's working for now. I'll come back to this question of implementing TLS or SSL later, in my voluminous spare time. It appears to be a very powerful program and should carry me through to the next millenium...

(snip of problem) When setting up Dovecot, I found that a lot of helpfull information was put into /var/log/maillog (or wherever syslogd sends mail logs on your system). Since you didn't post anything from that file, I'm not sure if you consulted it.

[Dovecot] Just installed with Fedora 2
by Michael J. Pawlowsky 26 Aug '04

26 Aug '04

I just upgraded my RH9 installation to Fedora 2. To my surprise, imapd seems to be gone from the core. I noticed there are now two IMAP servers docevot and cyrus. After reading brief descriptions of both, dovecot would seem to be more compatible with my setup. Especially since I'm using mbox's. I have 2 questions. It seems like dovecot does not support mailboxes inside of a directories. Am I right in thinking this? Second I get the error message: The current command did not succeed. The mail server responded: Error in IMAP command MYRIGHTS: Unknown command. My client is Thunderbird. Any work around for this? Thanks, Mike

[Dovecot] 0.99.10.x auth memory leak?
by Christian Balzer 26 Aug '04

26 Aug '04

Hello, running 0.99.10.6 (but seen it before that, too). Also (quite obviously) running 5 auth processes, given the fact that this is a pretty busy box and I didn't want to introduce any artificial bottlenecks. Alas with them eating up half of the free memory (which would go to a much better use as FS cache) I'm getting sorta concerned. If it's not a leak, it's caching something rather needlessly and inefficiently (the LDAP DB memory footprint for ALL users is less than this and the box below just serves half of those). This box sees about 0.5 million POP3/IMAP logins/day. --- PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 31235 root 16 0 220m 216m 5560 S 0.0 10.7 25:01.54 dovecot-auth 31234 root 16 0 205m 202m 5560 S 0.0 10.0 24:08.84 dovecot-auth 31231 root 16 0 200m 196m 5560 S 0.7 9.7 23:25.37 dovecot-auth 31232 root 16 0 196m 192m 5560 S 0.0 9.5 23:10.44 dovecot-auth 31233 root 15 0 179m 175m 5560 S 0.3 8.6 22:13.07 dovecot-auth --- So, I guess my questions to Timo are: Think it's leaky and any idea where? Given the load, would a single auth process be a bad idea? (it is a quite fast dual opteron box) Regards, Christian Balzer -- Christian Balzer Network/Systems Engineer NOC chibi(a)gol.com Global OnLine Japan/Fusion Network Services http://www.gol.com/

[Dovecot] [PATCH] pass struct io * to io_loop_handle_add()/io_loop_handle_remove()
by Andrey Panin 25 Aug '04

25 Aug '04

Hello, currently I'm working on new ioloop handler which uses epoll(4) API introduced in Linux kernel 2.6. In this API each fd added to fd set by epoll_ctl system call can be accompanied with user supplied data (integer or void pointer). epoll_wait syscall reports arrived events as an array of structures containing event mask and user data. Attached patch replaces fd and condition parameters passed to io_loop_handle_add() with struct io pointer. Now io_loop_handle_add() can pass this pointer as user data to epoll_ctl syscall and when event arrives we will have corresponding io structure pointer for free withiot traversing possibly long ioloop->ios list. Please take a look. Best regards. -- Andrey Panin | Linux and UNIX system administrator pazke(a)donpac.ru | PGP key: wwwkeys.pgp.net

Hi, I installed Dovecot on FreeBSD 4-STABLE machine and have a problem. MTA is postfix delivering to ~/Maildir, runs perfectly. Dovecot is configured to use plaintext auth, config file is at the end of this mail. When trying to get mail via IMAP, I'm getting the following errors: /var/log/dovecot.log > Aug 24 12:00:35 Info: Dovecot starting up > Aug 24 12:00:51 Info: Login: goshik [193.233.44.234] /var/log/maillog > Aug 24 12:00:51 banka dovecot: We couldn't drop root group privileges > Aug 24 12:00:51 banka imap(goshik): child 2045 (imap) returned error 89 Am I missing something?
