[Dovecot] @2.0, --sysconfdir incorrectly populated with dovecot/*.conf
by PGNet Dev 10 Oct '09

10 Oct '09

to document from #irc, in 1.2.x, specifying ./configure ... --sysconfdir=/path/to/dir ... correctly results in dovecot.conf looked for as "/path/to/dir/dovecot.conf". in 2.0, dovecot incorrectly creates a dovecot dir in the sysconfdir, and looks for, /path/to/dir/dovecot/dovecot.conf 2.0's behavior should be made consistent with the correct implementation in 1.2.x, or clarified as different in --help/docs. thanks.

[Dovecot] very frequent disconnections
by Dan Christensen 09 Oct '09

09 Oct '09

I've installed dovecot 1:1.1.11-0ubuntu4.1 on my jaunty system. Access from the same host works well, but when I access remotely (from various MUAs and networks) I get *very* frequent disconnects. Authentication is fine, and I can usually open a mail folder, but larger operations such as copying 20 messages into an imap folder always get disconnected. I can reconnect, but I often get disconnected again in a few seconds, especially if I do more than very light access. I've enabled all the logging I'm aware of, but I don't see any explanations. I get things like Oct 7 20:19:38 jdc dovecot: auth(default): new auth connection: pid=390 Oct 7 20:19:39 jdc dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=129.100.75.85^Irip=65.95.132.250^Ilport=143^Irport=62044^Iresp=<hidden> Oct 7 20:19:39 jdc dovecot: auth-worker(default): pam(jdc,65.95.132.250): lookup service=dovecot Oct 7 20:19:39 jdc dovecot: auth-worker(default): pam(jdc,65.95.132.250): #1/1 style=1 msg=Password: Oct 7 20:19:39 jdc dovecot: auth(default): client out: OK^I1^Iuser=jdc Oct 7 20:19:39 jdc dovecot: auth(default): master in: REQUEST^I2^I367^I1 Oct 7 20:19:39 jdc dovecot: auth(default): passwd(jdc,65.95.132.250): lookup Oct 7 20:19:39 jdc dovecot: auth(default): master out: USER^I2^Ijdc^Isystem_user=jdc^Iuid=1000^Igid=1000^Ihome=/home/jdc Oct 7 20:19:39 jdc dovecot: IMAP(jdc): Effective uid=1000, gid=1000, home=/home/jdc Oct 7 20:19:39 jdc dovecot: IMAP(jdc): maildir: data=~/Maildir Oct 7 20:19:39 jdc dovecot: IMAP(jdc): maildir++: root=/home/jdc/Maildir, index=, control=, inbox=/home/jdc/Maildir Oct 7 20:19:40 jdc dovecot: IMAP(jdc): Connection closed bytes=303/1423 and Oct 7 20:43:54 jdc dovecot: auth(default): new auth connection: pid=6620 Oct 7 20:43:55 jdc dovecot: auth(default): client in: AUTH^I1^IPLAIN^Iservice=imap^Isecured^Ilip=129.100.75.85^Irip=65.95.132.250^Ilport=143^Irport=62633^Iresp=<hidden> Oct 7 20:43:55 jdc dovecot: auth-worker(default): pam(jdc,65.95.132.250): lookup service=dovecot Oct 7 20:43:55 jdc dovecot: auth-worker(default): pam(jdc,65.95.132.250): #1/1 style=1 msg=Password: Oct 7 20:43:55 jdc dovecot: auth(default): client out: OK^I1^Iuser=jdc Oct 7 20:43:55 jdc dovecot: auth(default): master in: REQUEST^I5^I6594^I1 Oct 7 20:43:55 jdc dovecot: auth(default): passwd(jdc,65.95.132.250): lookup Oct 7 20:43:55 jdc dovecot: auth(default): master out: USER^I5^Ijdc^Isystem_user=jdc^Iuid=1000^Igid=1000^Ihome=/home/jdc Oct 7 20:43:55 jdc dovecot: imap-login: Login: user=<jdc>, method=PLAIN, rip=65.95.132.250, lip=129.100.75.85, TLS Oct 7 20:43:55 jdc dovecot: IMAP(jdc): Effective uid=1000, gid=1000, home=/home/jdc Oct 7 20:43:55 jdc dovecot: IMAP(jdc): maildir: data=~/Maildir Oct 7 20:43:55 jdc dovecot: IMAP(jdc): maildir++: root=/home/jdc/Maildir, index=, control=, inbox=/home/jdc/Maildir Oct 7 20:44:00 jdc dovecot: IMAP(jdc): Disconnected in APPEND bytes=1081/1965 The output of dovecot -n is: # 1.1.11: /etc/dovecot/dovecot.conf # OS: Linux 2.6.28-15-generic x86_64 Ubuntu 9.04 log_timestamp: %Y-%m-%d %H:%M:%S ssl_cert_file: /etc/ssl/certs/dovecot.pem ssl_key_file: /etc/ssl/private/dovecot.pem verbose_ssl: yes login_dir: /var/run/dovecot/login login_executable: /usr/lib/dovecot/imap-login login_greeting_capability: yes max_mail_processes: 25 mail_max_userip_connections: 20 mail_privileged_group: mail mail_location: maildir:~/Maildir mail_debug: yes maildir_copy_preserve_filename: yes auth default: verbose: yes debug: yes passdb: driver: pam userdb: driver: passwd The clients I have tried are Gnus (with starttls and gnutls-cli) and evolution, on a jaunty system; and k9mail-beta on an HTC Dream cell phone.

To them it just appears that the connection was closed. Any idea what could be causing this? Or how to debug it? Thanks, Dan -- Dan Christensen jdc(a)uwo.ca

[Dovecot] Binary locations
by Timo Sirainen 09 Oct '09

09 Oct '09

Where do you think the following binaries should be installed to? The possible locations are: - bin/ - sbin/ - libexec/dovecot/ (or lib/dovecot/ in most Linux distros) So the binaries are: 1) These probably belong to bin/ or sbin/ or both: - authtest - dovecotpw - doveadm 2) Binaries that you might want to call from mail_executable setting: - rawlog - gdbhelper 3) Index file dumping programs, mostly meant for debugging problems: - idxview - listview - logview - mailboxlogview - threadview 4) Some extra tools that might be useful sometimes: - imap-utf7 : Encode/decode IMAP mailbox names (mUTF-7 <-> UTF-8) - maildirlock : Lock a Maildir, primarily intended for compressing files in maildir And perhaps some of the binaries should be renamed? The authtest actually now looks like a bad name. Maybe it should have been "doveauthtest" or "dovecot-authtest" or ..?

[Dovecot] Using sieve with virtual delivery & maildir
by Jerry 09 Oct '09

09 Oct '09

I am using Postfix virtual users/domains with Dovecot virtual delivery to maildir style mailboxes. Now I want to get sieve working to sort out a few minor delivery problems. I want all mail with a message header "Delivered-To: foo+bar(a)domain.com placed in the /var/mail/vhost/example.com/foo/new directory. Would this work: require "fileinto"; if anyof (header :contains "Delivered-To" "foo+bar(a)domain.com") { fileinto "foo(a)example.com"; stop; } Running 'sieve-test' works OK; however, I do not want to implement it and suddenly start losing mail. -- Jerry gesbbb(a)yahoo.com Outside of a dog, a book is a man's best friend: and inside a dog, it's too dark to read.

[Dovecot] how to config dovecot for multiple domains, multiple SSL certs, and conditional IP access -- with passwd-file passdb?
by PGNet Dev 09 Oct '09

09 Oct '09

at them moment, i've configured dovecot for a flat passwd-file, annd static userdb. from dovecot.conf, ... auth default { mechanisms = plain digest-md5 cram-md5 user = mail ... passdb passwd-file { args = /data/mail/users/imap_user_file } userdb static { args = static uid=mail gid=mail home=/data/mail/store/Domains/%d/Accounts/%n quota=maildir:storage=4096 nice=10 } ... i'd like to configure dovecot to, host multiple domains, each on a separate IP setup a separate SSL cert for each domain respond with a different login_greeting for each domain restrict access to, and access type (e.g., TLS req'd vs noTLS, secure auth OK) of, imap login based with conditional rules based on the guest's IP address. all of these things are currently implemented on the non-dovecot imap server i'm migrating _from_, and i'd like to preserve these capabilities. can any/all of these be accomplished with a passwd-file flatfile lookup? i know i can restrict IP access in passwd-file with 'allow_nets=', but atm i'm unclear how i'd do that for multiple domains, etc. i understand that much can be accomplished with custom SQL queries, but for a small install would _prefer_ to stay flat file. i'm finding bits & pieces of capability in docs, etc -- but, so far, nothing comprehensive/all-inclusive. which makes me wonder a bit -- why not? any comments/advice would be much appreciated. thanks!

[Dovecot] Move messages marked as Spam
by michel＠casa.co.cu 08 Oct '09

08 Oct '09

Hello I have implemented recently in my work bogofilter to mark messages as Spam or Ham, currently is working perfectly, but I want to move those messages marked as spam to a folder called spam. I installed dovecot-sieve with the intention of using fileinto to accomplish this. my question is: where I put this: require "fileinto"; if header :contains "X-Bogosity" "Spam" { fileinto "Spam"; } so that all messages that come to my users go into the spam folder? and how i handle messages that are marked as "Unsure" X-Bogosity: Unsure Thanks Michel ---------------------------------------------- Webmail, servicio de correo electronico Casa de las Americas - La Habana, Cuba.

[Dovecot] Logging in with '+' delimiter
by Jerry 07 Oct '09

07 Oct '09

Dovecot v1.2.4 FreeBSD-7.2 I have Postfix configured to use Virtual Users & Domains and use Dovecot for virtual delivery. Postfix also sends, dovecot correctly places mail with '+'addressing; i.e., "foo+bar(a)domain.com" into "path-to-mail/domain.com/foo+bar". The problem is when I attempt to access the mailbox, the user name: foo+bar(a)domain.com is rejected. Is this by design, or is there a way to circumvent this problem? -- Jerry gesbbb(a)yahoo.com Fortune favors the lucky.

[Dovecot] Is it possible to authenticate against Active Direcotry using the whole e-mail?
by Δημήτριος Καραπιπέ ρης 07 Oct '09

07 Oct '09

Hi all! Is it possible to authenticate against Active Directory, using the whole e-mail address and not the user part (%n), so that if you support mutiple domains, all users should authenticate with their e-mail addresses. I use auth_bind_userdn = DOMAIN \ %u but somehow the *mail* attribute of Active/LDAP should be employed. thanks in advance Dimitrios Karapiperis
