[Dovecot] Recipient delimiters, deliver and SQL databases
by Nils Vogels 13 Dec '06

13 Dec '06

Hi! As a new user, I'm trying to set up a postfix + dovecot combination, and so far all is running smoothly. I'm using the guidelines that came with postfix and adjusting them as I go. My user and alias database is stored in MySQL, using the scheme from 'PostfixAdmin' (http://high5.net/page9.html) and I am using the dovecot LDA 'deliver' to drop messages into mailboxes that exist solely as virtual users. Users can login using both pop3 and imap, and retrieve the e-mails sent directly to them, so I'm happy with that. One of the features supported by postfix, and required for my setup is recipient delimiters. Using recipient delimiters, you can basically send extra information in the e-mail address, to maybe deliver the message into subfolders directly, or to run anti-spam software such as TMDA against. When I try to deliver such a message, I get a user unknown: Dec 9 14:25:01 vm-mail postfix/pickup[91477]: 4574A6420: uid=0 from=<root> Dec 9 14:25:01 vm-mail postfix/cleanup[91487]: 4574A6420: message-id=<20061209142501.4574A6420(a)vm-mail.mydomain> Dec 9 14:25:01 vm-mail postfix/qmgr[91478]: 4574A6420: from=<root(a)vm-mail.mydomain>, size=290, nrcpt=1 (queue active) Dec 9 14:25:01 vm-mail dovecot: auth(default): master in: USER 1 user+test@mydomain service=deliver Dec 9 14:25:01 vm-mail dovecot: auth-worker(default): sql(user+test@mydomain): SELECT maildir, 143 AS uid, 143 AS gid FROM mailbox WHERE username = 'user+test@mydomain' AND active = '1' Dec 9 14:25:01 vm-mail dovecot: auth-worker(default): sql(user+test@mydomain): User not found Dec 9 14:25:01 vm-mail dovecot: auth(default): master out: NOTFOUND 1 Dec 9 14:25:01 vm-mail postfix/pipe[91489]: 4574A6420: to=<user+test@mydomain>, relay=dovecot, delay=0.14, delays=0.07/0.03/0/0.04, dsn=5.1.1, status=bounced (user unknown) Relevant snippets from postfix's master.cf: # Dovecot LDA dovecot unix - n n - - pipe flags=DRhu user=dovecot:dovecot argv=/usr/local/libexec/dovecot/deliver -d ${recipient} and postfix's main.cf: virtual_gid_maps = static:143 virtual_mailbox_base = /mail/virtual virtual_minimum_uid = 125 dovecot_destination_recipient_limit = 1 virtual_transport = dovecot virtual_uid_maps = static:143 and dovecot's dovecot.conf: protocol lda { postmaster_address = postmaster@mydomain sendmail_path = /usr/sbin/sendmail auth_socket_path = /var/run/dovecot-auth-master } auth default { passdb sql { args = /usr/local/etc/dovecot-mysql.conf } userdb sql { args = /usr/local/etc/dovecot-mysql.conf } socket listen { client { path = /var/spool/postfix/private/auth mode = 0660 user = postfix group = postfix } master { path = /var/run/dovecot-auth-master mode = 0600 user = dovecot group = dovecot } } } And offcourse dovecot-mysql.conf: # Database driver: mysql, pgsql driver = mysql # Currently supported schemes include PLAIN, PLAIN-MD5, DIGEST-MD5, and CRYPT. default_pass_scheme = CRYPT # Database options connect = host=myhost dbname=mydb user=myuser password=mypass password_query = SELECT password FROM mailbox WHERE username = '%u' AND active = '1' user_query = SELECT maildir, 143 AS uid, 143 AS gid FROM mailbox WHERE username = '%u' AND active = '1' #EOF Now, I am pretty sure the problem lies with the %u, expanding to user+test@mydomain, which in some way should become user@mydomain, since the latter is the actual mailbox name of the user, but: how?

[Dovecot] dovecot imap mbox multiple connections
by Danni Allen 12 Dec '06

12 Dec '06

Hi, The company that I work for are currently looking at a changeover in clients from pegasus mail(v4) to Thunderbird (v1.5.0.8). We run dovecot (v 0.99.13) with mbox. We currently have a bunch of shared folders sitting in a dummy imap account that they all connect to and view. I have read that problems with Thunderbird have been encountered with this setup due to multiple connections to the account and that a possible solution is to convert from mbox to maildir. I was simply wondering if anyone knows anything about this, as I don't seem to be able to find any information on it other than a single thread with a single comment with what seems like anecdotal evidence rather than something acknowledged. Is there a problem with this? Rgds, Danni Allen

Eric, thanks, works fine now, the debian package is updating only the pop3d and not the imapd. Needed to install it seperately.

Hello, I'm using 0.99.14 with debian 2.6.8-2-386 #1 Tue Aug 16 12:46:35 UTC 2005 i686 GNU/Linux and exim4. I use the shared folder with symlinks, created by the script create_dovecot_shares-1.06. I have set the permissions and use umask 0007 on dovecot and in exim in maildir_home: directory_mode = 0770 mode = 0660 every thing works well, but if I'm moving a mail from my inbox with thunderbird into the shared mailbox it gets permissions -rw------- 1 user group 11811 2006-12-09 12:58 1165785386.P10056Q2M666099.blupp:2,Sa instead of -rw-rw---- 1 xxx group 31970 2006-12-10 17:26 1165767986.H344527P28279.blupp:2,Sb What am I doing wrong? kind regards Uwe

[Dovecot] 'NO' 'Unknown error'
by Nagy László 11 Dec '06

11 Dec '06

Dear List, I'm writting a program in Python that connects to a dovecot server and copies/moves messages across different shared folders. The program throws an error while executing this IMAP command: UID COPY 232 Archive/Notifications The same program works fine with other directories and messages. This is the response from the dovecot server: ('NO', ['Unknown error']) Do you have an idea what is the problem? This error message is very cryptic, it does not tell anythig about what is causing the problem and how to fix it. By the way, I'm using dovecot-1.0.r7_2 on FreeBSD 6.1-RELEASE. I cannot upgrade to a newer - I had to downgrade to r7 before because dovecot did not find the inboxes of my POP3s users. (But it did find the same inboxes for my IMAPs users.) Thanks, Laszlo

[Dovecot] Using custom Maildir subfolders with pop3 deliveri
by Bojan Popovic 11 Dec '06

11 Dec '06

Greetings, I am trying to make my antispam protection on user basis. So I need something like .junkmail folder in every user maildir. But the problem I am having is that my mail client can not download mail put in .junkmail folder. I am usin POP3 only, Maildir mailboxes (default_mail_env = maildir:/var/mail/%u) and whether I make folder with leadin dot or not it is never shown in mail client. Sincerely I don`t even know if it is posible with POP3, but it would be very hard converting to IMAP at this moment. Thanks in advance.

[Dovecot] Problems with Mailstorage path.
by Raja T Nair 11 Dec '06

11 Dec '06

Hi all, my environment: dovecot-1.0.rc15 Fedora Directory Server 1.0.2 Currently I've configured dovecote to find user's mail folder like this: dovecot.conf mail_location = maildir:/var/vmail/%d/%u/Maildir All my domain mailboxes are under /var/vmail, as evident. But there are some users whose mail folders are directly under /var/vmail like this one: /var/vmail/myuser1(a)mydomain1.com also, some have their folder names starting with caps like: /var/vmai/mudomain1.com/Myuser1(a)mydomain1.com This creates problems when these users try to login. Here I want dovecote to kind of assemble the mail storage path from mailMessageStore ldap attribute of the particular user. i.e, dovecot should add the mailMessageStore attribute's value to /var/vmail. Can somebody help me in solving this issue? regards, raja. -- +91 944 715 5548(Cell)

[Dovecot] Huge IMAP folder takes forever
by Peter Lindgren 10 Dec '06

10 Dec '06

Hi! Just updated to 1.0 rc15, but the problem remains. I think it could be client-dependent to some extent. I have only IMAPS access and Maildir. I have one mailbox which contains some 10,200 mails. That mailbox takes forever (have waited 30 minutes and then aborted) to open with Thunderbird 1.5.0.7. Other mailboxes (like dovecot :-), only 6984 mails) opens quickly. When Thunderbird tries to open this folder, the imap process on the server uses roughly all cpu resources. There isn't much disk I/O, at least as far as I can tell by listening at the server. The dovecot is upgraded from 0.99.something. Should I remove index files first, and in that case which? Is there something cached in Thunderbird? Here's the directory listing for the troublesome folder: -rw------- 1 peter peter 28 Jan 7 2006 .customflags -rw------- 1 peter peter 49248 Feb 7 2006 .imap.index -rw------- 1 peter peter 420998 Feb 7 2006 .imap.index.data -rw------- 1 peter peter 10256 Feb 7 2006 .imap.index.log -rw------- 1 peter peter 49200 Feb 7 2006 .imap.index.tree drwx------ 2 peter peter 686592 Dec 10 15:06 cur -rw------- 1 peter peter 64 Jun 6 2006 dovecot-keywords -rw------- 1 peter peter 619832 Dec 10 15:04 dovecot-uidlist -rw------- 1 peter peter 162992 Dec 10 15:21 dovecot.index -rw------- 1 peter peter 8826880 Dec 9 15:36 dovecot.index.cache -rw------- 1 peter peter 33776 Dec 10 15:22 dovecot.index.log -rw------- 1 peter peter 193660 Dec 3 12:50 dovecot.index.log.2 drwx------ 2 peter peter 512 Dec 10 15:06 new drwx------ 2 peter peter 512 Dec 10 15:04 tmp Thanks in advance, Peter -- Peter Lindgren, dataingenjör E-post: peter "at" norrskenkonsult punkt com http://www.norrskenkonsult.com

[Dovecot] Configuring for virtual users
by Gerard Seibert 10 Dec '06

10 Dec '06

I haven't tried this yet; however, I would like to know if it would work. Using Postfix, I am setting up numerous virtual users. These users obviously do not have an account on the mail server. I have created a "domain.net" account. Assuming that Postfix is properly set up to deliver to the specified accounts, which will be held under the "domain.net" directory, will this work in the dovecot.conf file: # default_mail_env = maildir:/var/mail/%d/%u or do I need to modify it somehow? -- Gerard
