[Dovecot] Rotating the dovecot log file
by Jerry 24 Oct '09

24 Oct '09

Using FreeBSD-7.2, I am attempting to configure the system newsyslog utility to rotate the dovecot.log file. I would prefer to use the system utility rather than the one described on the dovecot wiki for rotating the file. Unfortunately, it is not working. This is the error message that is spawned: newsyslog: illegal signal number in config file: /var/log/dovecot.log root:wheel 0666 1 * $M1D0 CJ /var/run/dovecot/master.pid USR1 Does anyone have an idea how to get this to work? Thanks! -- Jerry gesbbb(a)yahoo.com |::::======= |::::======= |=========== |=========== | Wilner's Observation: All conversations with a potato should be conducted in private.

[Dovecot] New error messages
by Robin Atwood 23 Oct '09

I was glancing at my logwatch report when I noticed: dovecot: IMAP(robinmail): fchown(/home/robinmail/mail/.imap/INBOX/dovecot.index.log.newlock, -1, 10(wheel)) failed: Operation not permitted (egid=100(users), group based on /var/mail/robinmail): 1 Time(s) dovecot: IMAP(robinmail): fchown(/home/robinmail/mail/.imap/INBOX/dovecot.index.tmp, -1, 10(wheel)) failed: Operation not permitted (egid=100(users), group based on /var/mail/robinmail): 3 Time(s) So what's going on here? :) I am fairly sure I never had them before.

[Dovecot] v2.0.alpha2 released
by Timo Sirainen 23 Oct '09

23 Oct '09

http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz http://dovecot.org/releases/2.0/alpha/dovecot-2.0.alpha2.tar.gz.sig Changes since alpha1: - All debug messages are now logged to debug log (debug_log_path setting, defaults to info_log_path). Patch by Pascal Volk. - Added support for SORT=DISPLAY IMAP extension. - Added doveadm who command for listing currently logged in users. - ssl_ciphers_list: Disable anonymous and export ciphers by default. - mail_chroot can now contain %variables (e.g. /home/%u) - fixed a bad maildir crashing bug - ssl-params is now run with +15 priority when generating the ssl parameters - Redesigned how login processes log in and create imap/pop3 processes. This fixes several settings and some other problems, plus it's now also possible for a single imap/pop3 process to handle multiple connections. If you want to try this, modify master.conf: service imap { # comment out: #service_count = 1 # This should be at least the number of CPUs, maybe more (2-3x?) process_min_avail = 4 # Limit the number of clients a single process can handle. # Disk IO is blocking, so some commands can take a while. client_limit = 5 } It currently doesn't even try to group same user's connections to same process, they'll just go randomly to whichever process manages to accept it first. Some day perhaps there should be a new service in the middle that keeps track of existing connections and forwards new ones to right mail processes. v2.0.beta1 TODO list: - master.conf has to be somehow put into defaults, so doveconf -n doesn't show its contents. an example master.conf would be minimal and show only those settings that admin might want to change (and those would show up in doveconf -n) - verbose_proctitle=yes is now quite useless because of the imap/pop3 process creation change. Probably enable linux-proctitle-hack and start changing the proctitle much more often. For example it could contain the command that's currently being run by user. And login processes could contain how many client connections they currently have. And other processes too something similar.. - change plugin hook design to allow multiple users in same process to run different plugins See alpha1 release announcement for more about these TODO: - v1.x config backwards compatibility - dsync is buggy - config process is slow - tcp-wrappers support

[Dovecot] Capability info in hello message not complete?
by Michal Hlavinka 23 Oct '09

23 Oct '09

Hi, one Fedora user complains about not some troubles after update to dovecot 1.2. He suspects wrong capability information given by dovecot 1.2 In dovecot.conf he uses imap_capability= option. While response to 'A CAPABILITY' respects imap_capability value, the capability info in hello message does not. for imap_capability=IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN A CAPABILITY response is: * CAPABILITY IMAP4 IMAP4rev1 ACL NAMESPACE CHILDREN SORT QUOTA THREAD=ORDEREDSUBJECT UNSELECT IDLE STARTTLS AUTH=PLAIN but hello message is: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. But it seems even when imap_capability is not used capability in hello message is not complete: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE STARTTLS AUTH=PLAIN] Dovecot ready. vs. * CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE SORT THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT IDLE CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH STARTTLS AUTH=PLAIN is this expected? Do you think capability information in hello message really can befool clients? Regards, Michal Hlavinka

[Dovecot] HA Dovecot Config?
by dovecot＠corwyn.net 23 Oct '09

23 Oct '09

Hi! I'm currently running Dovecot 1.1.8 on a HP server using CentOS 5.2 as my IMAP server, receiving mail from postfix, and also using squirrelmail as the frontend. As I look at upgrading the mail server, I'd like to change to a higher availability configuration (where the server can fail and I don't have to reconfig my imap users). For the SMTP that's easy, because I can use multiple MX records, and I can redirect a port forward from one server to another. But IMAP doesn't have the same functionality, because it's the storage that matters. What's the "best" way to do that? Clustered servers using a SAN? NAS? some sort of appliance in front? Suggestions? Thanks! Rick Rick Steeves http://www.sinister.net In reality nothing is more damaging to the adventurous spirit within a man than a secure future - Alexander Supertramp

[Dovecot] doveadm who
by Timo Sirainen 23 Oct '09

23 Oct '09

Pascal Volk suggested this, and it was pretty quick to implement for Dovecot v2.0. Ideas welcome how to improve it, or if it's already perfect :) The first line is written to stderr, so |sort can be used: # doveadm who|sort username # (ips) (pids) timo 1 (127.0.0.1) (2457) tss 2 (127.0.0.1) (617 1345) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) # doveadm who|sort -k2 -nr username # (ips) (pids) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) tss 2 (127.0.0.1) (617 1345) timo 1 (127.0.0.1) (2457) You can filter connections: # doveadm who 127.0.0.2 username # (ips) (pids) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) # doveadm who 127.0.0.0/24 username # (ips) (pids) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) timo 1 (127.0.0.1) (2457) tss 2 (127.0.0.1) (617 1345) # doveadm who tss username # (ips) (pids) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) tss 2 (127.0.0.1) (617 1345) # doveadm who tss 127.0.0.1 username # (ips) (pids) tss2 2 (127.0.0.2 127.0.0.1) (2392 2799) tss 2 (127.0.0.1) (617 1345)

[Dovecot] Need a little shadow to MySQL conversion help
by Marc Perkel 22 Oct '09

22 Oct '09

Excuse me for being stupid and confused. I'm trying to convert my dovecot install from passwd-file to mysql. I have a single table called "users" that has 3 fields, user_name, domain_name and password. The data came from passwd/shadow files so it uses the same password encryption as the shadow files do. The directory where the email is stored is calculated elsewhere and not stored in the database. The UID and GID are both mail for all virtual users. The user logs in passing the full email address and the password. So - what would be the config for using MySQL? Do I even need a userdb? If so - what would it be? Thanks in advance.

[Dovecot] VZW Blackberry BIS problems?
by B. Cook 22 Oct '09

22 Oct '09

Ever since Columbus day things have been strange with my two dovecot servers, according to my Blackberry users. We do not have a BES just the standard BIS that comes with a personal account. Several people have told me that since that Monday that they get occasional duplicate copies of messages which only appear singularly in their Maildir inboxes. I myself even called VZW and got transferred to RIM themselves where they 'reset' my account; (same as me going into the BIS server and deleting and adding again) only to have the same thing happen; again occasionally.. Below is relevant dovecot info.. -r-xr-xr-x 1 root wheel 164064 Oct 1 17:16 /usr/local/sbin/dovecot (date it was built; prior to any problems.. *whew*) ;) 1 # 1.2.4: /usr/local/etc/dovecot.conf 2 # OS: FreeBSD 7.2-RELEASE-p3 i386 3 ssl_cert_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 4 ssl_key_file: /usr/local/etc/lighttpd/ssl/mail.poughkeepsieschools.org.pem 5 disable_plaintext_auth: no 6 verbose_ssl: yes 7 login_dir: /var/run/dovecot/login 8 login_executable: /usr/local/libexec/dovecot/imap-login 9 login_greeting: mail.poughkeepsieschools.org OK 10 first_valid_uid: 89 11 last_valid_uid: 89 12 first_valid_gid: 89 13 last_valid_gid: 89 14 maildir_copy_preserve_filename: yes 15 mail_plugins: quota imap_quota 16 imap_client_workarounds: delay-newmail outlook-idle tb-extra-mailbox-sep 17 auth default: 18 mechanisms: plain login 19 user: vpopmail 20 passdb: 21 driver: vpopmail 22 userdb: 23 driver: vpopmail 24 socket: 25 type: listen 26 client: 27 path: /var/run/dovecot/auth-client 28 mode: 438 29 plugin: 30 quota: maildir:User quota 31 expire: Trash 7 Spam 30 Now what does not show here is something that I put in that it looked like it was supposed to help but didn't.. mailbox_idle_check_interval = 30 after looking around at other people complaining about BIS and possible dovecot issues it seemed that that entry was the 'magic' the BIS was missing; except I never had it and never had troubles. I'm assuming this is a BIS issue of some sort, but I can't tell. After looking on the wiki I didn't see anything that says "BIS users look here for tips.. " So I'm assuming there aren't any; I think it should just work with the IMAP server.. Any help would be appreciated as everyone thinks this is 'our problem' and "if we had an exchange server we wouldn't be having these problems.." Thanks in advance..

[Dovecot] Public Folders
by Peter Fraser 22 Oct '09

22 Oct '09

Hi All I'm trying to implement public folders. My dovecot -n readout is at the bottom. I created a maildir called resumes in /home/public Its contents are: mail# ls -la /home/public/resumes total 6 drwx------ 3 vmail vmail 512 Oct 22 08:58 . drwx------ 4 vmail vmail 512 Oct 22 08:47 .. drwx------ 5 vmail vmail 512 Oct 22 08:58 Maildir -rw------- 1 vmail vmail 0 Oct 21 18:30 dovecot-acl-list Then I created a directory called resumes in /usr/local/etc/dovecot-acls and in it, I created the file dovecot-acl I put the following entries in dovecot-acl owner lrwstiekxa user=user1 rwl When I connect as user1 in thunderbird, right click on the inbox and go subscribe, I see a greyed out public which I cannot subscribe to. I do not see resumes.
