[Dovecot] New User: POP3 issues
by kyrrin＠bluefeathertech.com 09 Jul '06

09 Jul '06

Fellow dovecot'ers, I'm just getting started with Dovecot, and I'm not a programmer, so please be gentle. ;-) THE PLATFORM: NetBSD 3.0/SPARC, Postfix 2.3-RC8, current Dovecot RC (I forgot the number). Maildir-type directories. THE GOAL: To accommodate authenticated (remote) POP3 users with APOP or SSL/TLS, and allow users on the internal network (192.168.x.x) to just use basic POP3 without worrying about authentication. QUESTIONS: (1) Does the dovecot master daemon have to be running in order to call pop3- login from inetd, in response to POP connection attempts? If so, it could be a problem. I'm getting this error when I try to start the thing. featherweb: {339} /usr/local/sbin/dovecot Fatal: listen(110) failed: Address already in use featherweb: {340} (2) For apop authentication, how do I go about generating the shared secret file locally, for each user? Is there a script that came with dovecot or...? (3) Is there a trick, similar to postfix's 'postconf -n,' that will give a condensed output of dovecot's configuration file? (4) I'm currently using sasl auth for Postfix's SMTP auth function. How difficult is it to use Dovecot for the same thing? (5) GAAAAHHHHH! (Just on general principles, based on the hours I've spent trying to get everything working). Thanks in advance. --- Bruce 'Quietly Making Noise' Lane Blue Feather Technologies

[Dovecot] /var/dovecot /var/spool/mail permissions, setup help (w/ config info)
by Jeff Kowalczyk 08 Jul '06

08 Jul '06

(repost gmane message as list member) I need some help with Dovecot-1.0rc2 on Gentoo Linux. My test harness is one Thunderbird-1.5.0.4 client, storage using legacy mbox directories ported over from an old UW-IMAP/sendmail combo running on RHL 8. Config is intended to be passwd/pam, plaintext login allowed (until I migrate everyone to ssl). After this is working, postfix and dspam are to be added, unless someone can recommend a 'dovecot of smtp' to use. I'll tail the mail.log to illustrate the problem, then excerpt what I think are the relevant directory and config file listings. I'm paying particular attention to file ownership, but am loathe to just chown dovecot things unless I know why. Let me know if you want to see any other config info to help spot the problem. Thanks! # tail -n 30 /var/log/mail.log dovecot: Jul 05 18:35:25 Info: Dovecot v1.0.rc2 starting up dovecot: Jul 05 18:36:10 Info: auth(default): client in: AUTH 1 PLAIN service=IMAP lip=123.456.789.012 rip=098.765.432.109 dovecot: Jul 05 18:36:10 Info: auth(default): client out: CONT 1 dovecot: Jul 05 18:36:10 Info: auth(default): client in: CONT 1 AGplZmYua293YWxjenlrAHdvcmRwYXNzMQ== dovecot: Jul 05 18:36:10 Info: auth(default): client out: OK 1 user=namefirst.namelast dovecot: Jul 05 18:36:10 Info: auth(default): master in: REQUEST 1 25692 1 dovecot: Jul 05 18:36:10 Info: auth(default): master out: USER 1 namefirst.namelast system_user=namefirst.namelast uid=501 gid=12 home=/home/namefirst.namelast dovecot: Jul 05 18:36:10 Error: stat(/var/dovecot/namefirst.namelast) failed: No such file or directory dovecot: Jul 05 18:36:10 Info: IMAP(namefirst.namelast): Effective uid=501, gid=12 dovecot: Jul 05 18:36:10 Info: IMAP(namefirst.namelast): mbox: data=/var/spool/mail/namefirst.namelast:INDEX=/var/dovecot/namefirst.namelast dovecot: Jul 05 18:36:10 Info: IMAP(namefirst.namelast): mbox: INBOX defaulted to /var/spool/mail/namefirst.namelast/inbox dovecot: Jul 05 18:36:10 Info: IMAP(namefirst.namelast): mbox: root=/var/spool/mail/namefirst.namelast, index=/var/dovecot/namefirst.namelast, inbox=/var/spool/mail/namefirst.namelast/inbox dovecot: Jul 05 18:36:10 Info: imap-login: Login: user=<namefirst.namelast>, method=plain, rip=098.765.432.109, lip=123.456.789.012 dovecot: Jul 05 18:36:10 Error: IMAP(namefirst.namelast): open() failed with subscription file /var/spool/mail/namefirst.namelast/.subscriptions: Not a directory dovecot: Jul 05 18:36:12 Error: IMAP(namefirst.namelast): open(/var/spool/mail/namefirst.namelast/inbox, O_CREAT) failed: Not a directory dovecot: Jul 05 18:36:12 Error: IMAP(namefirst.namelast): mkdir_parents(/var/dovecot/namefirst.namelast/.imap/INBOX) failed: Permission denied dovecot: Jul 05 18:36:14 Info: IMAP(namefirst.namelast): Disconnected: Logged out # ls -al /var/spool/mail drwxrwxr-x 2 root mail 1472 Jul 2 19:20 . drwxr-xr-x 6 root root 168 Jul 3 14:19 .. -rw-r--r-- 1 root root 0 Jun 27 18:46 .keep -rw------- 1 namefirst.namelast mail 36243879 Jul 1 17:52 namefirst.namelast (...) # ls -al /var/dovecot/ total 0 drwxr-xr-x 2 root root 72 Jul 5 10:30 . drwxr-xr-x 14 root root 360 Jun 29 09:45 .. -rw-r--r-- 1 root root 0 Jul 5 10:30 .keep # ls -al /var/run/dovecot/ total 5 drwxr-xr-x 3 root root 176 Jul 5 18:35 . drwxr-xr-x 9 root root 504 Jul 3 14:45 .. srw------- 1 root root 0 Jul 5 18:35 auth-worker.25687 srwxrwxrwx 1 root root 0 Jul 5 18:35 dict-server drwxr-x--- 2 root dovecot 136 Jul 5 18:35 login -rw------- 1 root root 6 Jul 5 18:35 master.pid # ls -al /home/namefirst.namelast/ total 17791 drwxr-xr-x 2 namefirst.namelast mail 248 Jul 5 18:29 . drwxr-xr-x 76 root root 2512 Jul 2 20:21 .. -rw------- 1 namefirst.namelast mail 3293785 Sep 23 2005 Sent # grep dovecot /etc/group dovecot:x:97: # grep dovecot /etc/passwd dovecot:x:97:97:added by portage for dovecot:/dev/null:/usr/sbin/nologin # grep mail /etc/passwd mail:x:8:12:mail:/var/spool/mail:/bin/false postmaster:x:14:12:postmaster:/var/spool/mail:/bin/false # grep mail /etc/group mail::12:mail # grep namefirst.namelast /etc/passwd namefirst.namelast:x:501:12:First Last:/home/namefirst.namelast:/bin/bash # cat /etc/pam.d/dovecot auth required pam_unix.so account required pam_unix.so # cat /etc/dovecot.conf base_dir = /var/run/dovecot/ protocols = imap imaps pop3 pop3s listen = * shutdown_clients = yes log_path = /var/log/mail.log info_log_path = /var/log/mail.log log_timestamp = "%b %d %H:%M:%S " syslog_facility = mail disable_plaintext_auth = no ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem ssl_key_file = /etc/ssl/private/dovecot.pem login_chroot = yes login_user = dovecot default_mail_env = mbox:/var/spool/mail/%u:INDEX=/var/dovecot/%u mail_extra_groups = mail mail_debug = yes protocol pop3 { pop3_uidl_format = %08Xu%08Xv } auth_verbose = yes auth_debug = yes auth_debug_passwords = yes auth default { mechanisms = plain login passdb pam { args = dovecot } userdb passwd { } user = root } __________________________________________________ Do You Yahoo!?

[Dovecot] FYI: timosieved
by John Peacock 07 Jul '06

07 Jul '06

Just a heads up for all interested in using the Dovecot LDA with SIEVE scripting: I've started work on a proof-of-concept managesieve daemon, since the only one available right now is dependent on Cyrus. It appears that the only choice available for sites not using timsieved is the Ingo component of Horde, which is way too fat to install by itself (plus it uses FTP for a transport, which I make it a rule not to install). For testing purposes, I am hacking together a Perl module based on the Net::Server model (which is not suitable for production). If this goes well (the managesieve protocol is painfully stupid and the only tricky part is linking in libsieve), then I'll do a rewrite in C. It will authenticate directly to Dovecot through the auth-client (or auth-master) mechanism, so whatever SASL methods that Dovecot supports, it will support. I've decided that the eventual server will be called timosieved, in honor of our host, and echoing the original Cyrus timsieved. Don't bug me about when it'll be done... :) John -- John Peacock Director of Information Research and Technology Rowman & Littlefield Publishing Group 4501 Forbes Boulevard Suite H Lanham, MD 20706 301-459-3366 x.5010 fax 301-429-5748

[Dovecot] default_mail_env and IMAP server directory in client
by Dirk Essl 07 Jul '06

07 Jul '06

Hi, I'm currently installing a dovecot Server to be a replacement for an uw-imapd. I dont want to touch the clients configuration, because I have too much users... Situation is the following: the mbox files are in the users homedirectory (~/MailImap), automounted via nfs In dovecot.conf I've set default_mail_env = mbox:%h/MailImap:INBOX=/var/mail/%u It works perfect without a value in Firefox' setting 'IMAP server directory' but in all clients tis is set to '~/MailImap' so it doesnt show subfolders I already tried to symlink various things in the MailImap directory and different values of default_mail_env, but I cannot mak it work. Any suggestions? It would help if dovecot could discard the IMAP server directory setting of the client, but I am not a programmer and dont know where to look in the source :-( -- TIA dirk

[Dovecot] 1.0.rc2 ldap in Solaris
by Tomi Vainio 07 Jul '06

07 Jul '06

Hi, Earlier it was possible to compile ldap support in Solaris 10 but currently it fails in src/auth/db-ldap.c line 341 because LDAP_SASL_QUIET is missing. I can found eg. LDAP_SASL_INTERACTIVE from headers. Tomppa

[Dovecot] Newbie on Fedora 5
by Yudhvir Singh Sidhu 06 Jul '06

06 Jul '06

Hey Guys, I want to transition from Merak to Postfix/Dovecot. I am not sure how to begin. I have been reading the different Howtos - cocktail of services to Postfix like ClamAV, Spamassissin, Greylisting, Jamm, SquirrelMail. The thing is that I want stable IMAP mail. Here is what I want to do: a. Stand alone linux box for email only - 25 users b. provide IMAP and web c. provide SSL authentication, spam filtering and virus checking. d. I would perfer to setup flat file, or unix based SIMPLE authentication scheme. e. Current users are on windows and are popping mail. Although we have LDAP, can we have another LDAP server which lives with existing server? f. I have Fedora 5 installed. I have Dovecot, Postfix, Cyrus-SASL installed. As well as webmin to manage it all. Any suggestions to get running quickly? h. I need to preserve the popped mail sitting in user Outlook clients. -- Yudhvir Singh Sidhu, 3-4039

Our's though is that we authenticate using SFU and nis. So in addition to the folder needing to be lowercase, the username has to be as well. It hasn't be discussed in a while but Timo mentioned that the %L wouldn't work for username's. To workaround it, I used this patch. However, I have no idea how it works with other authentication methods as we use passwd and I haven't tested it since test69 so it probably needs tweaking. -- Jeff Graves, MCSA Image Source, Inc. 508.966.5200 x31 www.image-src.com -----Original Message----- From: dovecot-bounces(a)dovecot.org [mailto:dovecot-bounces@dovecot.org] On Behalf Of Johannes Berg Sent: Thursday, July 06, 2006 2:35 PM To: Paul Blankenship Cc: dovecot(a)dovecot.org Subject: Re: [Dovecot] bug/feature On Thu, 2006-07-06 at 09:13 -0700, Paul Blankenship wrote: > I don't know if this has been mentioned here or even thought of in > the > grand scheme of things and I'm just sending a one time email about it > "just in case" > I recently swapped my server around and I'm using dovecot now....LOVE > it!

I think you can lower-case the name just about anywhere, e.g. default_mail_env = maildir:/home/%Lu/.mail instead of default_mail_env = maildir:/home/%u/.mail See /usr/share/doc/dovecot-common/variables.txt (on debian systems, otherwise just look for variables.txt) johannes

[Dovecot] courier-imap transition
by Joseph W. Breu 06 Jul '06

Hello All, I am transitioning from a courier-imap installation where the POP3 UIDLs are of the format: 28 UID10823-1064256714 29 UID10829-1064256714 30 UID10830-1064256714 31 UID10833-1064256714 32 UID10836-1064256714 33 UID10847-1064256714 34 UID10859-1064256714 35 UID10893-1064256714 36 UID10903-1064256714 37 UID10904-1064256714 The dovecot UIDL list for the recommend courier version 2 configuration produces: 432 1150908803-432 433 1150908803-433 434 1150908803-434 435 1150908803-435 436 1150908803-436 437 1150908803-437 438 1150908803-438 439 1150908803-439 I need to produce a UIDL map similar to that of courier-imap.

[Dovecot] bug/feature
by Paul Blankenship 06 Jul '06

I don't know if this has been mentioned here or even thought of in the grand scheme of things and I'm just sending a one time email about it "just in case" I recently swapped my server around and I'm using dovecot now....LOVE it! Could use a bit more intuitive error messages, but otherwise, it's great! But there is one flaw that I've run into with my users. Case sensitivity. As you all know, Linux is case sensitive and windows is not and mail should always be lower case. I have users who are checking Thisemail(a)domain.tld instead of thisemail(a)domain.tld. This causes my build to create a folder for Thisemail(a)domain.tld to check instead of pulling mail from thisemail(a)domain.tld Either rate, I'm correcting users when I find it, but it doesn't help when I have those that USE ALL CAPS BECAUSE EITHER IT'S COOL OR THEY USE IT FOR OTHER PURPOSES AND DON'T TURN IT OFF. No, I'm not yelling, I'm being sarcastic :) Anyway, just incase noone was aware of that little "issue".... -- Paul Blankenship Solano Computer Resource 441 Georgia St. Suite 200 Vallejo, CA 94590 (707)645-9652 Fax: (707)649-4360 For all your business and residential computer and Internet needs.
