[Dovecot] Duplicate e-mails
by Lisa Wu 10 Aug '06

10 Aug '06

Hi, I've got Postfix/Dovecot config mail server, POP3/mbox, and a few users are complaining about duplicate e-mails. User connects with Outlook 2003 to Dovecot to download mail. If you check the mail logs for that message ID, only one copy is delivered to his mailbox. Also, verified that the client is set-up to NOT leave a copy of the message on the server. He downloads a copy of the e-mail once, and then 2 minutes later when his client reconnects to check for mail, he gets another copy of that e-mail. It's not a consistent problem. I check the dovecot logs, and see his client connecting and disconnecting, and always deleting the same number of e-mails it downloads. Is this a network issue or a config issue? The only other thing to note is that it's usually an e-mail sent to a group list that he's a member of. And I've set-up the owner-list setting in the aliases file. So I don't think that's the problem. If anyone can shed some light on this issue, it'd be greatly appreciated. Thanks, Lisa

[Dovecot] Something other than dotlock for uidlist locking?
by James Berry 10 Aug '06

10 Aug '06

If I read the code correctly, only dotlocks are supported for locking of dovecot-uidlist. And I don't see any settings in the config file for it. As it turns out, dotlocks are very slow on my system, due to their implementation via hardlinks. Would it be possible to support other locking mechanisms for locking of the uidlist file? -jdb

[Dovecot] Newbie Questration
by Yudhvir Singh Sidhu 10 Aug '06

10 Aug '06

Actually, it is a frustration: The client does not work, have tried Opera mail and Outlook, to receive mail. the client can send, but not receive. I know the mail is sitting in the user account Maildir ready to be picked up. Dovecot "compiles" fine. What am I doing wrong? Someone please help me, I know it is something simple. I have racked the net trying to find a solution, but no 2 mail setups are the same. My setup is the simplest I can make it. I have Postfix and Dovecot installed on Linux. All recent versions. Plain text authentication off shadow passwords and login user accounts. Mail is configured as Maildir, IMAP. As you can see below, I have turned logs on and there is nothing in them that shows an error. I am on a real static IP behind a firewall. I have opened the SMTP and IMAP ports. BTW, Postfix can send and receive local and outside. IMAP does not work to/fro outside or locally. I have also logged into Dovecot like so: telnet localhost imap 1 login test testing 2 select INBOX It lets me login and I have tried it with root, which it rejects and with another account which works. It selects the INBOX and I hit the return key multiple times to exit because I don't know what else to type. So, it looks like it is authenticating. Postfix is working fine, it can send and receive mail both locally and the outside world. It puts the messages in the Maildir directories as it is supposed to. Here is my dovecot.conf file: protocols = imap imaps listen = * ssl_listen = * ssl_disable = no ssl_cert_file = /etc/pki/dovecot/certs/dovecot.pem ssl_key_file = /etc/pki/dovecot/private/dovecot.pem ssl_parameters_regenerate = 168 log_path = /var/log/dovecot info_log_path = /var/log/dovecot.info verbose_ssl = yes protocol imap { } auth_verbose = yes auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain login userdb passwd { } passdb shadow { }

[Dovecot] dovecot process dies

Hi to all. I upgraded my dovecot from rc5 to rc6. Prior to upgrading, it was working seamlessly. But now I couldn't start dovecot. Here's what the log says: Aug 10 10:39:17 proxy dovecot: Dovecot v1.0.rc6 starting up Aug 10 10:39:18 proxy dovecot: Login process died too early - shutting down Aug 10 10:39:18 proxy dovecot: child 29033 (login) killed with signal 11 Aug 10 10:39:18 proxy dovecot: child 29034 (login) killed with signal 11 Aug 10 10:39:18 proxy dovecot: child 29035 (login) killed with signal 11 Aug 10 10:39:18 proxy dovecot: child 29036 (login) killed with signal 11 Aug 10 10:39:18 proxy dovecot: child 29037 (login) killed with signal 11 Aug 10 10:39:18 proxy dovecot: child 29038 (login) killed with signal 11 I tinkered with the login_* configuration options but to no avail. The only configuration option that I removed is the login_max_logging_users, which is now deprecated in the new version. I tried to google about this problem but what I found were related to other processes such as imap etc. Thanks in advance for your help. -- Ceasar

[Dovecot] IMAP/POP3 proxying and capability
by Laurent Papier 10 Aug '06

10 Aug '06

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 for capability before authenticate to the server. So if the proxy capability are not the same as the final server capability the client gets wrong information. I use the QUOTA extension and it doesn't make sens to activate the quota feature on the proxy. Any other suggestion ? Perdition can hardcode the capability string the his configuration file. This is not perfect as the capability can change but it's an acceptable workaround for me. -- Laurent Papier - 03 88 75 80 50 Admin. système - SdV Plurimedia - <http://www.sdv.fr/>

[Dovecot] SSL hangs? Try this
by Timo Sirainen 09 Aug '06

09 Aug '06

Since apparently 1.0 RC5 didn't fix the SSL hangs for everyone, could you try if replacing src/login-common/ssl-proxy-openssl.c with this helps: http://dovecot.org/tmp/ssl-proxy-openssl.c It's basically the old proxying but with some new changes, plus hopefully also fixing the original rarely occurring hang which my rewrite was intended to fix.

I haven't had time to put together a patch, but quota-fs.c fails to compile on Mac OS X. Any chance we could get a configuration switch that says "--without- quota"? I've resolved the problem temporarily by forcing HAVE_FS_QUOTA to undef in quota-fs.h. James

Re: [Dovecot] Dovecot imap with Postfix and using Thunderbird as client
by Shawn Needham 09 Aug '06

09 Aug '06

Hi, I was wondering if anyone knew of the mysterious fix to this problem that Curtis describes in his followup: "I vaguely remember something like this, but I don't recall the fix" I recently installed dovecot on a server running RHEL4-AS-U2 and have updated to RHEL latest dovecot package, dovecot-0.99.11-2.EL4.1. Seeing as this is close to the version Curtis is running (dovecot-0.99.14) I was wondering if anyone had some insights. There seems to be a Thunderbird specific problem when trying to retrieve messages from the server. Other imap clients (Mac OSX Mail, squirrelmail, etc) don't experience this problem, however Thunderbird 1.5.0.5 experiences it on Linux, Mac OSX and Windows boxes. In thunderbird, new messages don't reliably appear and the retrieval button doesn't work when new mail is present. Clicking on an email which isn't cached retrieves new ones as well as waiting around an hour to retrieve messages. Thanks in advance for any insight you can provide.

[Dovecot] Can't move messages
by Paul van Erk 09 Aug '06

09 Aug '06

Hi, I use dovecot with IMAP over SSL and with Plain Text authentication. I've been using that for quite a while, but now (with my new PC), it's not working like it should (I tried several 1.0* releases, including 1.0-rc6. The problem is that I can't move messages from one IMAP folder to another, no matter which mail client. When I use KMail, I get: "The connection to the server parena was unexpectedly closed or timed out. It will be re-established automatically if possible." But everything still works. The messages hasn't moved (deleting (so send to Trash folder) also doesn't work), it stays where it is. With Thunderbird, it just goes nuts in the status bar saying "Connecting..." and some other messages: clearly it tries to move, loses the connection and tries again and again... An extra weird thing is when I move a message from my IMAP account to a local folder, it works. And then I can move that message from the local folder to my IMAP account. It only doesn't work when moving messages within the IMAP account. I use: openssh 4.3_p2-r1 openssl 0.9.7j I hope someone can help me, 'coz my wife will soon start to find it just as annoying as I already do. ;) Paul van Erk

[Dovecot] rc6 compilation problems (obsd 3.9 stable)

Starting with rc6, there seem to be problem with compilation on openbsd 3.9, (possibly due to autoconf 2.60 switch mentioned in other thread ?). Either way, this is what configure reports at some point (further compilation fails of course): checking for crypt... yes checking for dlopen... yes checking whether byte ordering is bigendian... no ./configure: echo $(top_builddir)/src/lib-storage/index/maildir/libstorage_maildir.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/mbox/libstorage_mbox.a: not found ./configure: echo $(top_builddir)/src/lib-storage/index/dbox/libstorage_dbox.a: not found checking zlib.h usability... yes checking zlib.h presence... yes checking for zlib.h... yes

[Dovecot] Dynamic server address
by Kresimir Tonkovic 08 Aug '06

08 Aug '06

Hi! My mail server (ubuntu breezey badger) is connected by ADSL and has a dynamic address. I have noticed that, every day after the IP address changes, dovecot is no longer reachable from the net. Iguess this is because dovecot doesn't register this change and continues to listen on a non-existing interface/address. I'm trying to solve this problem by putting a script in /etc/ppp/ip-up/ dovecot --===--- #!/bin/sh # By kresho # dovecot ip-up script (/etc/ppp/ip-up.d/dovecot) # /etc/init.d/dovecot restart ---===--- So far, it seems to work. I doubt I'm the first one to come across this problem, yet I couldn't find anything similar on google. Any comments? -- kresho

[Dovecot] RC6 startup failure: "Login prcess died too early"
by S JList 07 Aug '06

07 Aug '06

Greetings. I have been running Dovecot-1.0rc2 on a test server for the last couple of weeks. No problems. However, when I installed RC6 this morning, Dovecot refused to launch completely. Here's the relevant snippet from /var/log/maillog: Aug 7 10:08:36 mercury dovecot: Dovecot v1.0.rc6 starting up Aug 7 10:08:37 mercury dovecot: Login process died too early - shutting down Aug 7 10:08:37 mercury dovecot: child 26127 (login) killed with signal 11 Aug 7 10:08:37 mercury dovecot: child 26128 (login) killed with signal 11 Both RC2 and RC6 compiled cleanly with "--with-pop3d". For reasons beyond my control, I have to set protocols = imap pop3 disable_plaintext_auth = no ssl_disable = yes I do have a valid /etc/pam.d/dovecot file (we're using PAM). I made certain that the localized settings for /usr/local/etc/dovecot.conf matched what they were in RC2 for RC6. (I did use the RC6 dovecot-example.conf as source for RC6, then made the local changes. I also tried testing RC6 with my old RC2 config file--same failure). So, RC2 starts just fine. RC6 fails to start with the messages logged above. Can anyone give me any pointers? RHEL (Linux Kernel 2.6.9-34.0.2.ELsmp), built from source, nothing out-of-the-ordinary. Right now, I've reverted back to RC2. TIA. S JList sjlist(a)heidelberg.edu
