[Dovecot] beta8: core, signal 11
by Jeff A. Earickson 05 Feb '07

05 Feb '07

Timo, The gdb analysis is attached. It looks like memory got seriously stomped in this core dump. There was no assert or other useful information in the syslog. My setup: Solaris 9, imap and imaps, mbox format, INBOXes NFS mounted, index files on local ufs filesystem, beta8 configured like so: VERSION=1.0.beta8 CC=gcc CFLAGS="-g -O" CPPFLAGS=-I/opt/openssl/include LDFLAGS=-L/opt/openssl/lib \ ./configure --prefix=/opt/dovecot.$VERSION \ --with-ssl=openssl \ --with-ssldir=/opt/openssl/ssl \ --with-sql-drivers=no \ --disable-ipv6 \ > configure.out Jeff Earickson Colby College

[Dovecot] Advice, Converting a Live/Production server.
by Michael Dilworth 26 Jan '07

26 Jan '07

I want to mess with a live server. (a Bad thing). I have googled until my eyes boogled, wiki'ed until my fingers are wonked, have read as much as I can read, however I'm left with a few questions/worries. Issue: I am currently running Dovecot as a pop3 server with standard /var/mail mbox's I would like to run a mixed Imap/Pop3 server with ~/maildir inbox's The thread http://www.dovecot.org/list/dovecot/2006-February/011304.html is fairly close to what I want to do, but I would like to go ahead and convert to maildir. (Mixed pop3/imap access for each user) I don't have a system to test, "I used have one but it's now the production server... PW/Disk failed, thank G-D(s) for rsync/backups". Setup: procmail, dovecot 1.0 beta 8.2 (fc5), squirrelmail. all users use outlook (2000,2003) or outlook express (random versions) (^^^^ not my choice, I just have to deal with it {and use it} ^^^^^) the majority of users will continue to use pop3, however some would like to convert to imap and have all mail stored on the server. Questions: /etc/procmailrc? just set default to ~/maildir? do I need to define "INBOX"? aka $MAILDIR=~/maildir/, $ORGMAIL=~/maildir/, $DEFAULT=~/maildir/ Same as above, what about new/cur should I set up a /etc/skel? close to above, if I create rules, for spam, etc. do I need to worry about cur/new. close to above, what about Sent Items, Drafts etc... for imap users, I do understand that client rules would likely be needed to store sent items. conversion, anything to look for? mb2md seems to work, but some users have "don't delete from server set", will they get dups? (I can live with this) archiving, can I (or a script) mess with the files in the maildir? aka keep the number of files/messages less than 16k for the outlook users. Bugs, should I cool my heals, and wait for rc16 or 1.0 final? I am currently running problem free, and I do hate to mess with something which is not busted. TIA Michael.

[Dovecot] Disconnects with proxies
by Michael Kress 20 Jan '07

20 Jan '07

Hi, I know I shouldn't ask stuff like this when using dovecot-0.99.11-4.EL4 (CentOS-4.4), but why I'm asking this is whether it's worth to switch from rpm based upstream dovecot to a self compiled one or not and thus I think you wouldn't kill me presenting you this question. o:-) I've got a problem with dovecot regarding a pop3 proxy issue. When I configure my dovecot server to do just plain pop3 I can telnet from a windows box without any flaw, but as soon as the client uses some pop3 proxy (for example outlook uses avira antivir Mail-AntiVirus Protection), queries to that server fail. A log line looks like this: pop3-login: Dec 05 22:53:24 Info: Disconnected [::ffff:84.165.54.42] Moreover with the proxy activated, a telnet to port 110 (pop3) is not working properly, the cursor stays right behind "+OK dovecot ready." and as soon as I enter a character, the server rejects this character as an unknown command (Without pressing ENTER). As soon as I turn off the Antivir-Proxy the telnet to port 110 runs flawlessly and I can login. So I'd like to know is there anything I can do with this version or is it worth trying the newest version? Is this a known issue? Thanks in advance Michael -- Michael Kress, kress(a)hal.saar.de http://www.michael-kress.de / http://kress.net P E N G U I N S A R E C O O L

Hi all, Using rc15 here, with userdb and passdb in LDAP, no prefetcg. Dovecot keeps a thread open, so we can't shutdown our directory. Any ideas why? Thanks. -- Kind Regards, Gavin Henry.

[Dovecot] Authorization client connect failing
by Ryan Hinton 19 Jan '07

19 Jan '07

Hello, and thank you in advance for your valuable time. I am running Dovecot v1.0.rc15 on an OpenBSD 3.9 i386 machine (no time to upgrade yet). I downloaded the source from the dovecot site, compiled and installed without any problem. The server starts up find and runs for a while. After a few hours to a few days, the server stops sending the CAPABILITY statement when a client tries to login. I found a few descriptions of this problem on the web, but no satisfactory resolution. I added some debugging code to the functions in auth-client.c and got the following traces. Included in this email are a successful login attempt, a failed attempt, and a startup trace. I am not a UNIX sockets guru and don't know the dovecot internals well enough to figure out what's wrong. I am happy to add/remove debugging code as requested to help track down the problem, although it may take a few days for the server to hang again. I hope someone can help me figure out the problem so my mail server works reliably! Here is a successful login attempt. Dec 9 10:34:45 myhost dovecot: imap-login: DEBUG:: auth_client_is_connected?

[Dovecot] Connection to server time out when deleting (moving to Trash)
by Anders Lund 19 Jan '07

19 Jan '07

Hi, Running: * Dovecot 1.0 rc15 * Debian Sarge Linux Using Maildir and IMAP over SSL. When trying to delete a lot of mail (> 5000-6000 messages) in some folder, using Mozilla Thunderbird (1.5.0.7) on Ubuntu, I often experience "Connection to server <hostname> timed out." Any suggestions on how to fix this problem? "Empty Trash" seem to work fine, so I guess this is related to moving a lot of mail from one folder to another (Thrash)? - Anders -- Anders Lund <Anders.Lund(a)uninett.no> .~.

[Dovecot] default_mail_env/mail_location syntax changes
by Mike Brown 18 Jan '07

18 Jan '07

Sorry, I tried to find this info on the wiki and in the docs, but couldn't quite figure it out. Dovecot 1.0rc8 introduced this change: "mbox:/var/mail/%u" no longer works as the mail location. You'll have to specify the mail root explicitly, just like the examples always have: "mbox:~/mail:INBOX=/var/mail/%u" If I need a custom INBOX location but the default behavior of using the first of [/ or ~/mail or ~/Mail] having a .imap subdirectory, how do I go about specifying that? That is, on my system, - inbox file: ~/Mailbox - mail storage dir: ~/mail OR ~/Mail (it varies by user) - all files are in mbox format Thanks, Mike

[Dovecot] assertion failed
by Shaun T. Erickson 18 Jan '07

18 Jan '07

I installed dovecot on a RH9 server this evening, via an RPM from atrpms.net (dovecot-1.0-0_34.rc15.RHL9.at.i386.rpm). The auth portion is working perfectly, as I'm using it to do SMTP AUTH with my postfix 2.3.5 installation. I have configured it to provide imaps. When I connect to it, it rapidly connects, disconnects, connects ... ad infinitum, reporting this, in the logs, each time: Dec 30 16:03:33 max dovecot: imap-login: Login: user=<ste>, method=plain, rip=192.168.32.168, lip=65.206.7.147, TLS Dec 30 16:03:33 max dovecot: IMAP(ste): file istream-raw-mbox.c: line 499 (istream_raw_mbox_get_body_size): assertion failed: (rstream->mail_size != (uoff_t)-1) Dec 30 16:03:33 max dovecot:child 19228 (imap) killed with signal 6 Here is my dovecot.conf file: listen = [*] protocols = imaps disable_plaintext_auth = yes ssl_cert_file = /etc/postfix/max.blackdogsoft.net.crt ssl_key_file = /etc/postfix/max.blackdogsoft.net.key ssl_ca_file = /etc/postfix/cacert.pem default_mail_env = mbox:%h:INBOX=/var/mail/%u mail_read_mmaped = yes verbose_proctitle = yes protocol lda { postmaster_address = postmaster(a)blackdogsoft.net } auth default { mechanisms = plain login passdb pam { } userdb passwd { } socket listen { client { path = /var/spool/postfix/provate/auth mode = 0660 user = postfix group = postfix } } } Suggestions? -- -ste

Hey guys I have a user's machine that won't drop his POP3 connection, is there a way to set a timeout? I'm not seeing it in the default config or in the webmin module for dovecot, any ideas? Thanks! Jason Gretz Network Admin Angstman Law 208-850-9284 https://companyweb/
