[Dovecot] dovecot and outlook express and large messages
by Daniel 16 Nov '04

16 Nov '04

Hi I have been using Dovecot 0.99.11 and 1.0-test52 on a server with about 2000 accounts. All has been working good until a few days ago. Now I'm stuck and can't work out whats going on. The problem seems to be only with Outlook/outlook express clients. If the mail is large with an attachment its fails. After you hit the send and receive button after a while Outlook express gives the error "Your POP3 server has not responded in 60 seconds". Network activity seem to be minimal between the client and the server. There is no log entry out of the ordinary to say what went wrong. I have tried out a number of changes to the dovecot.conf file, none make any difference. Thanks for any help. Regards Daniel Rowe

[Dovecot] eudora issue
by kent crispin 16 Nov '04

16 Nov '04

There seems to be a protocol mismatch between eudora and dovecot when using pop. The login interchange with, for example, mozilla, is as follows: MO: [connects] DC: +OK dovecot ready. MO: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . MO: USER yyy DC: +OK MO: PASS xxxxxxxx DC: +OK Logged in. But with eudora, with apparently equivalent configuration, the sequence is as follows: EU: [connects] DC: +OK dovecot ready. EU: CAPA DC: +OK DC: CAPA DC: TOP DC: USER DC: UIDL DC: RESP-CODES DC: STLS DC: SASL PLAIN DC: . EU: auth PLAIN AG1tcgBtaXN0bGV0b2U= DC: -ERR Unsupported authentication mechanism. At this point eudora reports an error back to the user, and the connection fails. Can anyone shed any light on this? Is it just that there is an incompatibility in how eudora and dovecot view the protocol? Or is there some configuration option I need to tweak to make things work? Thanks for any help.

[Dovecot] (mail_index_expunge): assertion failed: (!t->view->external) Is this a bug?

Hi I am getting this a lot. Is this a bug? (mail_index_expunge): assertion failed: (!t->view->external) can be fixed by deleting the /home/<user>/mail/.imap directory. It has happened a few times with me. Regards Daniel Rowe

[Dovecot] RE: dovecot and outlook express and large messages
by Daniel 16 Nov '04

16 Nov '04

Hi Dose dovecot have problem working on a eth0:1 alias type interfaces? I just wondering if this could be my problem? Dovecot would do the authentication correctly and send small email but as soon as any load was put on it like downloading a mail with a large attachment it would fail. All network traffic would stop. No errors in the logs. As soon as I move the service to listen on a non alias interface eth0 all works fine. Very strange. I have taken a good look at our server to check that is not anything. I'm pretty sure we are good. I have also rebooted the box to see if that would fixed it which it didn't. Regards Daniel

[Dovecot] dovecot with different POP3S / IMAPS Certs
by Vincent Jaussaud 15 Nov '04

15 Nov '04

Hi, I'm new to dovecot, but actually planning to switch a wide WU-IMAP/POP installation to dovecot. With WU-IMAP, a different certificate can be used by pop3s and imaps, allowing both server to be reachable through different hostnames,without SSL complaints on the client side; this is mostly used for scalability. I'm trying to do the same thing with dovecot; that is having dovecot using a different certificate for it's pop3s instance and imaps instance. Unfortunately, in dovecot configuration file, only one certificate can be set; used by both pop3s / imaps. Any idea of the best way to handle this ? Thanks !

[Dovecot] dovecot-auth leaves zombies
by Stefano Maffulli 15 Nov '04

15 Nov '04

Hi all, I have installed and configured dovecot on two different machines, so I don't have much experience with this server. One installation is giving me serious problems, that I have a hard time tracing. From the beginning: the machine is a debian mix (stable/unstable) dovecot 0.9.11, real users authenticated via pam_ldap/nss_ldap. It serves ~70 users, all of them using Outlook, Outlook Express and IMP. The system seems to work just fine for a while, but after a some time, some dovecot-auth zombies start appearing. I can't really understand who/what is causing them. The only thing I see in the logs are these lines, very sporadically, but I still couldn't trace when they happened. Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnecting to LDAP server... Nov 5 09:40:28 csv-mail-01 dovecot-auth: nss_ldap: reconnected to LDAP server after 1 attempt(s) (BTW, also apache2 sends similar messages, I don't know if they are related) Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnecting to LDAP server... Nov 5 09:52:14 csv-mail-01 apache2: nss_ldap: reconnected to LDAP server after 1 attempt(s) After a while dovecot stops authenticating and needs to be killed and restarted (/etc/init.d/dovecot stop takes some time to actually stop dovecot processes). Do you have any clue of what is going on and where I can investigate further? I would like to say 'it's Outlook's fault', but I really can't. Any hint appreciated. regards stef

Hi, I have FC2/Sendmail/Dovecot default setup. I turned on POP3 and POP3S in /etc/dovecot.conf. I started out getting duplicates only when I was using Outlook w/ 'Leave copy on server' option. Lately, I've been getting duplicates at seemingly random messages sent to and from seemingly random users. Any help will be appreciated. Thanks, Jeff Ramsey Tubafor Mill, Inc.

[Dovecot] Popping without home directories
by Andre Grove 12 Nov '04

12 Nov '04

Hello there I tend to e-mail user accounts to my servers with /sbin/nologin and /dev/null as their shell and home directories respectively. I have discovered that Dovcot does not like it when a user does not have a home directory. Obviosly the user POP3 and not IMAP! :P Is there a work around for this? I have a suspicion it is one of the chroot option, but I do not know the meaning chroot. Thanks Andre

[Dovecot] Possible Bug

Okay in dovecot.conf I set the fallowing settings log_path = /var/log/dovecot info_log_path = /var/log/dovecot Then I setup log rotation for that file (using logrotate). But after it does the rotation. Dovecot dies. Now I know why this happens. But should it ? To over come this I now have it set to stop dovecot and start dovecot after it's done dealing with the log file. -- Chris L. Franklin --

[Dovecot] noob - integrating dovecot with postfix
by Mitch Pirtle 09 Nov '04

09 Nov '04

Hi list, Just jumped providers and am now desperately trying to get IMAP running on a new server... But not getting the link between postfix and dovecot working. :-( My two problems are: 1) local mail seems to get into the ~/Maildirs, but not from the outside (this is a postfix issue?) 2) I cannot find information on how to tell postfix to use virtual domains/addresses and then connect dovecot to them (as they are now in non-standard locations and/or formats) I'm sure this is a FAQ, but cannot find an example that would walk me though this. Can someone kindly point me in the right direction? -- Mitch

[Dovecot] Excessive imap-login and pop3-login processes
by Ben Beuchler 08 Nov '04

08 Nov '04

I'm running a Linux mail server with Postfix and Dovecot. I've noticed that the number of "imap-login" processes usually sits around 240, and "pop3-login" usually around 50 or so. The comments in the config file seem to indicate that, with my setup, I shouldn't see more than about 10 of each. Am I misunderstanding the config or is this expected behavior? login_process_per_connection = no login_processes_count = 10 login_max_processes_count = 128 login_max_logging_users = 256 The mail server receives about 1.5 - 3 logins per second and usually has around 75 simultaneous IMAP sessions. There are rarely more than 1 or 2 simultaneous POP3 sessions open. Thanks... -Ben -- Ben Beuchler There is no spoon. insyte(a)emt-p.org -- The Matrix

[Dovecot] dovecot 1.0-test52 build notes
by Mark E. Mallett 08 Nov '04

08 Nov '04

I thought I would try to use 'configure' to lay out the dovecot install a little differently than the default. I prefer all the support files under one tree (e.g. in /usr/local/lib/dovecot-1.0) rather than distributed around the filesystem. And I'd be happiest if all of the support files were just at that top level rather than in subdirectories. e.g.: /usr/local/lib/dovecot-1.0/dovecot.conf /usr/local/lib/dovecot-1.0/imap-login /usr/local/lib/dovecot-1.0/dovecot-auth etc. (I'm happy to have a "doc" subdirectory though.) And ideally I'd have the primary executable installed in a more generic place, but tagged with its version number, like /usr/local/sbin/dovecot-1.0 Note that I'm not suggesting this, just explaining what I am after. So the second to last thing I tried was: --program-suffix=-1.0 \ --bindir=/usr/local/lib/dovecot-1.0 \ --sbindir=/usr/local/lib/dovecot-1.0 \ --libexecdir=/usr/local/lib/dovecot-1.0 \ --sysconfdir=/usr/local/lib/dovecot-1.0 \ --datadir=/usr/local/lib/dovecot-1.0 \ --localstatedir=/usr/local/lib/dovecot-1.0 \ But that didn't really work, for the reasons listed in the "last" try below, plus all of the executables got the "-1.0" suffix, not just the "dovecot" program (not a big surprise..). And the last thing I tried: --bindir=/usr/local/lib/dovecot-1.0 \ --sbindir=/usr/local/lib/dovecot-1.0 \ --libexecdir=/usr/local/lib/dovecot-1.0 \ --sysconfdir=/usr/local/lib/dovecot-1.0 \ --datadir=/usr/local/lib/dovecot-1.0 \ --localstatedir=/usr/local/lib/dovecot-1.0 \ which kinda got me where I wanted, except that if I want a dovecot-1.0 executable in /usr/local/sbin I need to add that by hand, and also that the build process added another subdirectory "dovecot": /usr/local/lib/dovecot-1.0/dovecot/ I can (and did) manually remove that final directory and flatten out the tree, and fortunately you've made it possible to specify in dovecot.conf the paths to all the executables and so forth. But it would be nice to be able to create this desired layout entirely via configure and not have to move things around after the fact. Is that even possible? Obviously, don't spend a lot of time on it.. but if I'm missing an option that would get me where I want, I'd be interested in knowing about it. Oh, and "strings src/master/dovecot | grep /usr/local" gives this: /usr/local/lib/dovecot-1.0/dovecot.conf /usr/local/lib/dovecot/imap /usr/local/lib/dovecot-1.0/dovecot/imap /usr/local/lib/dovecot-1.0/run/dovecot /usr/local/lib/dovecot-1.0/dovecot/dovecot-auth /usr/local/lib/dovecot-1.0/dovecot/imap-login /usr/local/lib/dovecot-1.0/dovecot/pop3-login /usr/local/lib/dovecot-1.0/dovecot/pop3 /usr/local/lib/dovecot/pop3 So it looks like there are a couple of places where the configured paths aren't caught (or so it would seem).

[Dovecot] dovecot 1.0-test52 compile notes
by Mark E. Mallett 08 Nov '04

08 Nov '04

Compile issues on an older BSD/OS 4.2 system: src/lib/byteorder.h needs #include <netinet/in.h> to pick up in_addr struct src/lib/byteorder.c no "libgen" here (no basename()). Added it inline, no big deal, but you might want to have configure test for this and provide one if it's missing. Also, on this system there are no types like "uint8_t" and "uint64_t" -- instead there are the u_int8_t and u_int64_t et al types. I added some global typedefs, but I gather this is a somewhat common issue, so you might want to test for these. -mm-

[Dovecot] Runas Question
by Chris L. Franklin 08 Nov '04

08 Nov '04

Okay heres a weird question is there anyways to make dovecot run as root ? Heres why: I'm currently using XMail email server (smtp/pop3/virtual accounts). And I love using it. But it really must run as root. I've tryed all the non-root solutions for it. and really I'd prefer to have it run as root. And I'd like to really use dovecot as (on server with xmail). Currently I've got it running with some sendmail server and a few postfixs But really I'd like to get it working with Xmail. So if anyone has any Ideas or how to get Dovecot to run as root. PS. I know the Idea behind dovecot is security and how it's coded to be able to run using non-root accont. So please I'm really only looking for ways to get dove to run as root. And not new ways of reconfiguring my smtp servers so as they don't need to be run as root. -- Chris L. Franklin --

[Dovecot] Unread mail problem
by Clinton Mills 08 Nov '04

08 Nov '04

Okay, here is the set up. I have Outlook set up to keep mail on the server for 5 days. At some point I started downloading all my mail that was on the server over and over again, even though I already have the mail. The weird thing is that it did not download all the mail, just a few. For example it would download 6 messages, then 18, then 12, etc! After I tried it a few times I had 50 of the same message in Outlook? A small fix, but I do not want to so this ever time If I unclick save on server and then check my mail, it will delete all the mail in my mail box. Then I reclick the leave on server for 5 days and it will work fine! Any idea what is going on? Clinton Hitcents.com Tel: (270) 796-5063 ext 105# Fax: (270) 796-3195 Cell: (270) 996-1122
