[Dovecot] userdb prefetch not working for passdb sql
by dovecot-ri 31 Mar '06

31 Mar '06

Hi all, I'm using 1.0.beta3 and having problems using userdb prefetch in conjuction with passdb sql. Here are my mail logs when I log to virtual account "testuser(a)mydomain.com" by doing "telnet localhost 143": Mar 26 15:15:47 imapserver dovecot: Dovecot v1.0.beta3 starting up Mar 26 15:15:49 imapserver dovecot: auth-worker(default): mysql: Connected to (null) (mail) Mar 26 15:16:03 imapserver dovecot: auth(default): client in: AUTH 1 PLAIN service=IMAP secured lip=127.0.0.1 rip=127.0.0.1 resp=<hidden> Mar 26 15:16:03 imapserver dovecot: auth-worker(default): sql(testuser(a)mydomain.com,127.0.0.1): query: ***snipped, very long*** Mar 26 15:16:03 imapserver dovecot: auth(default): client out: OK 1 user=testuser(a)mydomain.com Mar 26 15:16:03 imapserver dovecot: auth(default): master in: REQUEST 1 16001 1 Mar 26 15:16:03 imapserver dovecot: auth(default): passwd(testuser(a)mydomain.com,127.0.0.1): unknown user Mar 26 15:16:03 imapserver dovecot: auth(default): prefetch(testuser(a)mydomain.com,127.0.0.1): userdb_uid not returned Mar 26 15:16:03 imapserver dovecot: auth(default): prefetch(testuser(a)mydomain.com,127.0.0.1): userdb_gid not returned Mar 26 15:16:03 imapserver dovecot: auth(default): userdb(testuser(a)mydomain.com,127.0.0.1): user not found from userdb Mar 26 15:16:03 imapserver dovecot: auth(default): master out: NOTFOUND 1 Mar 26 15:16:03 imapserver dovecot: imap-login: Internal login failure: user=<testuser(a)mydomain.com>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured The MySQL query is long and complicated, but here's what it returned when I copied and pasted it into mysql: user testuser(a)mydomain.com password {SSHA}BRuPgonpb8Zd+0NaFH2G6dT47m3mT43w userdb_home /var/mail/mydomain.com/testuser userdb_uid vmail userdb_gid vmail All of these values are correct. It seems to be ignoring the userdb_* fields. It works when I don't use prefetch, and it also works when I do use prefetch but change the SQL query to return "testuser" instead of "testuser(a)mydomain.com" in the user field. Anyone know why? Here's my dovecot.conf in case it proves useful: first_valid_uid = 900 mail_debug = yes default_mail_env = maildir:%h/.maildir maildir_copy_with_hardlinks = yes protocol imap { login_greeting_capability = yes } protocol pop3 { } auth_verbose = yes auth_debug = yes auth default { mechanisms = plain passdb sql { args = /etc/dovecot/dovecot-sql.conf } passdb pam { args = "*" } userdb passwd { } userdb prefetch { } user = root } plugin { } Thanks!

[Dovecot] Dovecot abort while selecting INBOX
by Joshua Wise 31 Mar '06

31 Mar '06

Hello all, Recently, I was setting up SpamAssassin and procmail on my system (used to run Courier, and was converted using Courier convert scripts). I was setting up a rule in PINE to filter all previously marked SPAM messages into a folder, when I suddenly got disconnected from the IMAP server. I attempted to reconnect, but any attempts to access my INBOX would disconnect me. I looked in /var/log/mail.log on my server, and found this: Mar 26 12:42:17 dashnine dovecot: imap-login: Login: user=<joshua>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Mar 26 12:42:17 dashnine dovecot: imap(joshua): Trying to allocate 0 bytes Mar 26 12:42:17 dashnine dovecot: child 31035 (imap) killed with signal 6 Looks like Dovecot aborted. I grabbed a tcpdump of the event after turning off SSL, which is available at http://joshuawise.com/pine.imap.tcpdump . My system is, summarized: * A Linux x86 machine: Linux dashnine 2.6.12.3 #2 Sun Aug 7 18:56:14 EDT 2005 i686 GNU/Linux * A Debian machine: testing/unstable * Running Dovecot from Debian: 1.0.beta3 * Converted from Courier using convert scripts * Using Postfix and Procmail * Using Maildirs in home directories (although in this case, lrwxrwxrwx 1 joshua joshua 23 Mar 11 22:08 Maildir -> /media/Maildirs/joshua/) * Using PINE connecting to Dovecot on localhost to access email Let me know if you want more information, or if you want me to try anything in particular. Thanks, joshua

[Dovecot] Confused about what MTA, MDA, IMAP/POP server to use
by Netlink Tech 31 Mar '06

31 Mar '06

Hello...I'll TRY make this short. This post is not specific to Dovecot...but many subscribers to this list have probably been down this road. (private replies welcome if you want it to go off list) I currently use Sendmail with MailScanner, SpamAssassin, ClamAV, Procmail, and qpopper for POP3 (hash mail dirs for mbox files)on RedHat 9 server. Roaming users currently only have the option of UebiMiau webmail interface to POP3 (doesn't work well) I will be moving to a server with Fedora Core 5.(x86_64) Things I would like to accomplish: 1) Move to maildir mailbox format (currently large mbox files cause I/O flushing errors and problems for users retrieving). 2) Use squirrelmail for webmail (IMAP) (local or roaming users) 3) Enable local users (ones with current accounts on the server) to continue to use their current client setup. 4) Enable any user to use the webmail interface to retrieve/send email. 5) Enable roaming users (ones connected from any location) to use Outlook Express or similar with SMTP_Auth and port 587 for message submission and POP3/IMAP. 6) Enable mail quota. I want the current users to use their current settings (unless they roam...then require that they use webmail or SMTP_Auth and port 587), but moving forward with new users, I have no reason to give them shell access/system accounts....so I was thinking virtual users using user@domain and storing their auth information in mysql db. (mysql will be used for radius...so it is already running on the server). Because I am trying to figure out how to keep the existing users system accounts and move forward with new users only having virtual accounts (just mail access with no login), I don't think I can use file system quotas. I have used Sendmail for 10 years, so I am familiar with it and it has been very stable for me. (so I prefer to stick with it if I can) I rely heavily on MailScanner to scan/mark/clean virus and Procmail to filter marked spam. Qpopper is on the way out...A couple of weeks messing with the test server and I already love Dovecot. Questions: 1) Recommendations please: How to accomplish with what configuration. 2) Quotas? 3) SMTP_Auth using Mysql for virtual users? (works fine with PAM/system passwords) Sorry for not being Dovecot specific on the list. Curt

Re: [Dovecot] Support for Kmail maildir format

Then we have Evolution, which also uses maildirs but with yet another subfolder naming format (subfolders are created right beside the cur, new and tmp directories). In both cases, the folder names are not UTF-7 encoded on disk, which is worth noticing. -- Magnus Holmgren

At the moment when a project finishes we have to move it to another store so that it's not clogging up everyone's public folder list. Allowing people to only see the folders they want is one of the features that has attracted us to shared namespaces. > Unfortunately I don't think it's easy to currently make namespace's > subscriptions exist in another namespace.

Don't add it in the TODO - you've already done it (basically). I'd cobbled together a real kludge to use the dovecot-shared permissions on the subscriptions file (kinda - only the group permissions, not the user) and was about to post it to the list when I came across the way you'd already handled it. The subscriptions file is stored in the folder pointed to with the "CONTROL" directive - I just put this to a separate place for every user and it works fine. The only thing that's left is getting this added to the Wiki - I don't think anyone's done that yet.

[Dovecot] sig11 with 1.0.beta3 on openbsd-i386
by David Gwynne 30 Mar '06

30 Mar '06

i recently helped a friend of mine migrate from imap-uw using mboxes to dovecot on top of Maildirs and came up against two issues. this is quite embarrassing as ive been claiming dovecot is Solid As A Rock(tm) and hasn't ever given me any issues. 1. if dovecot runs out of file descriptors it will loop forever trying to open new logging pipes. the code in question is at line 624 of src/master/login-process.c 2. we get a sig11 in the imap process. heres the bt: dlg@mail dlg$ gdb -c imap.core /usr/local/libexec/dovecot/imap GNU gdb 6.3 Copyright 2004 Free Software Foundation, Inc.
