[Dovecot] Dovecot config
by Dien Phan 04 Apr '08

04 Apr '08

Hi, I've installed dovecot 1.0.13 on FreeBSD 6.3 RELEASE and now trying to configure it. Below is my config file: $ dovecot -n # 1.0.13: /usr/local/etc/dovecot.conf log_path: /var/log/dovecot.log info_log_path: /var/log/dovecot-info.log protocols: imap ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: maildir:~/Maildir dotlock_use_excl: yes maildir_copy_with_hardlinks: yes mail_plugins: antispam imap_client_workarounds: delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep auth default: verbose: yes passdb: driver: checkpassword args: /var/MailRoot/bin/dovecot_xmail userdb: driver: static args: uid=vxmail gid=vxmail home=/var/MailRoot/domains/%d/%n allow_all_users=yes socket: type: listen master: path: /var/run/dovecot/auth-master mode: 384 user: vxmail plugin: antispam_signature: X-DSPAM-Signature antispam_trash: Trash antispam_spam: SPAM antispam_dspam_binary: /usr/local/bin/dspam antispam_dspam_args: --user;%u We are using a web mail software that allows users to login either as us 'abc' or 'abc@domain'. The problem is: when a user logs in as 'abc' (without domain part) dovecots creates a directory /var/MailRoot/domains/abc and check mail there (as I understand because %d is blank). My question is how to config dovecot so it automatically add default domain %d is blank. Thank you for help. Dien Phan

[Dovecot] Icedove (Thunderbird) crashes when reading IMAP messages
by Cam Ellison 04 Apr '08

04 Apr '08

This is a Debian lenny/sid installation. Dovecot has been installed on it for over a year, with no problems. Lately (i.e. the past few months), if I attempt to read a message, Icedove crashes. It does not do this when I read a message downloaded from the ISP's POP3 server (not that I do this very often - almost all my mail goes through Dovecot). I am now having to read email with KMail, but cannot send from it - that's another story. Googling for the past month or so reveals nothing: there seems to be no bug filed for this, and indeed I think it is an odd communication problem with dovecot that has not been seen before. Has anyone any experience with this, or any ideas how I should go about resolving it? I have not done so (because I don't know how to use the data, not being a coder), but can run strace and/or valgrind on icedove if that will help.

[Dovecot] shared Sent and Junk folders
by Tolga 03 Apr '08

03 Apr '08

Hi, For some odd reason, two of my users share the same Sent and Junk folders, therefore I keep getting errors about Sent folder reading permissions and one user reading the other user's Junk folder. What can I do about this odd problem? Regards, Tolga -- Stay with *nix :)

[Dovecot] Lmtp between hosts? (postfix/dovecot/ldap)
by k bah 02 Apr '08

02 Apr '08

I have 2 hosts: (a) - dovecot-1.0.5-6 - postfix-2.4.5-20 -> It's not the mx record for the domain, just holds the mailboxes -> Postfix uses LDAP for user lookup, dovecot too. -> Works ok if I set it to be the final mail destination, with Cyrus and Dovecot LDA (mailbox_transport). -> Has no domain associated (dns) with this ip address (b) - postfix-2.3.2-28 -> Has the mx record for that domain, has ip address that the domain points to. (users @ domain.org) -> Works ok if I install dovecot and set the mailbox_transport to be on this machine, both with dovecot and cyrus. What I'm trying to do: Have host (b) to receive mails for that domain, and by setting it's transport_maps to be /etc/postfix/transport, and there (tranport maps) point to host (a), using ltmp: "domain.org lmtp:ip_address_machine_A:24" ("domain.org lmtp:inet:ip_address_machine_A:24" does not work, gives me "fatal: valid hostname or network address required in server description: inet:ip_address_machine_A:24") Both machines have /etc/services with lmtp to port 24 tcp/udp. http://www.postfix.org/transport.5.html was not so clear to me. Ok, when I took out the "inet" part on the transport maps file, it connected to the host (a), which has this on master.cf: "machine_A_ip_address:24 inet n - n - - lmtp" it "worked", since machine (b) (received the mail and has mx record) delivered the mail to machine (a) (holds mailboxes, runs dovecot), but that stopped, machine (b) connects to port 24 on machine (a), and stays there, connected, without saying nothing (sniffed it). When I kill the connection (kill postfix on machine (a)), machine (b) complains on the log file: postfix/lmtp[704]: msg_id: to=<xx(a)xx.yy>, relay=machine_A[machine_A]:24, delay=223, delays=0.08/0.01/223/0, dsn=4.4.2, status=deferred (lost connection with machine_A[machine_A] while receiving the initial server greeting). -- questions -- I don't know if I'm doing things wrong (configuration error) or the wrong thing (should try other ways), so my questions: 1) Is this setup going to work ever, or it's wrong to try to get it to work? I want to hold mailboxes on a different host, and now I got to use dovecot (in case I hear: "try it with cyrus instead" =o)). 2) Viewing from the machine that receives the mail, and has mx record, the transport should be lmtp, right? Since it's now a matter of "delivery". Postfix: <...> -> <qmgr> -> (<local> or <smtp> or <pipe>) When using lmtp, I'm in <local>?? I mean, to get the message to the other machine (just mailboxes, no mx) I SHOULD USE LMTP(?) 3) Viewing from the machine holding the mailboxes, is there a way to make dovecot listen on that port? Or should I continue to use Postfix, and use postfix on this machine to deliver to dovecot (dovecot lda config works ok if using 1 and only 1 machine for everything - mx record, mailboxes). With Cyrus I talked lmtp directly, Postfix receives the mail and uses lmtp to talk to cyrus, using a unix socket. If anyone replies to the topic, and the discussion goes deeper on some of the alternatives, I paste my configs and come with further details, since what's working isolated I didn't paste here. Previous tests with just Cyrus or Dovecot on 1 machine setup worked, so I think it would just "bloat" the mail with information. thanks = -- Powered by Outblaze

[Dovecot] Alert when quota is warning

Hello. Is it exist a plugin to alert when a POP/IMAP account has a warning quota (like 90%)? Or, do you know a solution to do it? The alert could be an email sent. Thanks. - Nicolas.

[Dovecot] Outlook cant connect to POP server.
by "Fábio M. Catunda" 02 Apr '08

02 Apr '08

Hi, I'm having a weir situation with MS Outlook and dovecot. I'm using POP for some users, some can connect, others cant. With tcpdump I got this packet coming from client to server: 2008-03-31 18:30:20.913718 IP (tos 0x0, ttl 128, id 1082, offset 0, flags [DF], proto: TCP (6), length: 48) 192.168.12.9.1072 > 192.168.5.124.110: S, cksum 0x90db (correct), 2564735473:2564735473(0) win 65535 <mss 1460,nop,nop,sackOK> E..0.:@...c.... ...|.0.n........p............... But the server never give an answer. I don't have any idea why the server do not answer, in error.log and info.log I got nothing. Dovecot version: 1.0.rc15-2etch3 (Debian package) And those are the workarrounds that I enabled: pop3_client_workarounds = outlook-no-nuls oe-ns-eoh I'm kind of lost, any tip is appreciated! Thanks!

[Dovecot] v1.1.rc4 released
by Timo Sirainen 01 Apr '08

01 Apr '08

http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz http://dovecot.org/releases/1.1/rc/dovecot-1.1.rc4.tar.gz.sig I didn't have time/energy to fix everything I wanted, so it'll probably be a few more RCs left until v1.1.0. This is anyway an important release, because it fixes two buffer overflows in search code which have been in all v1.1 releases (but not v1.0). Really stupid mistakes, I must have been tired or something when writing the code.. Anyway I now added code to notice these kind of buffer overflows when they happen (if --enable-debug is used), so hopefully these will be the last ones. * Fixed two buffer overflows in str_find_init(). It was used by SEARCH code when searching for headers or message body. Added code to catch these kind of overflows when compiling with --enable-debug. Found by Diego Liziero. + LDAP: Added debug_level and ldaprc_path settings (OpenLDAP-only) + Squat: Added fts_squat = partial=n full=m settings. See the wiki. - dbox metadata updating fixes. - quota: backend=n didn't work - SEARCH RECENT may have returned non-recent messages if index files were created by v1.0. - If mailbox was opened as read-only with EXAMINE, STOREs were permanently saved. - LDAP: Templates were somewhat broken (by richs at whidbey.net)
