[Dovecot] migrating to dovecot
by Alexandre Chapellon 30 Mar '11

30 Mar '11

Hello, I am trying to setup a migration scenario from an proprietary solution to dovecot IMAP/POP3. Whereas am only at the strating point, things appear quite complicated because of the following reasons: - The proprietary solution uses special/own/proprietary mailbox format (wich is more like maildir but is not maildir) - I don't have direct access to the filesystem where the mails are stored. The best I could do would be a snapshots of the filesystem - I have about 1,5TB of mail data. - Having users to be forced to empty their mailbox before migration or re-download their whole mailbox after migration would be something hard for me to present as a correct option. Am looking for advices that would avoid me loosing time searching in bad directions. Or even point me to a miraculous tool thatdoes all magic while i have a beer :) Best regards. -- horoa: la voie est libre

I am curious why these do not seem to match? It especially bothers me that the modes set are different. Am I missing something? Thanks. -Walt

[Dovecot] 1.2 problem 'dovecot -n' vs dovecot.conf
by Walt Shekrota 30 Mar '11

30 Mar '11

To elaborate, if there is a database associated with this setup it is really fubar. note: tail of dovecot -n lda: postmaster_address: postmaster mail_plugins: sieve quota_full_tempfail: yes deliver_log_format: msgid=%m: %$ rejection_reason: Your message to <%t> was automatically rejected:%n%r auth default: mechanisms: plain login passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/run/dovecot/auth-client mode: 504 socket: type: listen client: path: /var/spool/postfix/private/dovecot-auth mode: 432 user: postfix group: postfix plugin: sieve: ~/.dovecot.sieve sieve_dir: ~/sieve This in no way represents the settings in my dovecot.conf. It seems to have rembered old .conf settings and mixed them. At no time was mode 504 set or even 432. What am I doing wrong? Thanks. -Walt I'm also toying with the idea of loading 2.x if I can figure out the PPA stuff.

Hi Where does this utility reside for installation. I use Ubuntu and installed dovecot-imapd and dovecot-pop3d so far. Does it now ship in the regular dovecot installation packages? Thanks. -Walt

How disable lookup in another LDAP places exept ou=Mail, dc=ph, dc=com? Thanks for answers.

[Dovecot] Upgrade to v2.0 conf file fails
by Nikolaos Milas 29 Mar '11

29 Mar '11

Hi, I am trying to use the command: doveconf -n -c dovecot-1.conf > dovecot-2.conf to upgrade my dovecot.conf file, but it fails (see below). Judging from the message that vsz_limit is the new setting for login_process_size, I have retried using login_process_size=256 rather than login_process_size=64 (which was the initial value), but the error persists. Please advise.

[Dovecot] file permissions
by Walt Shekrota 29 Mar '11

29 Mar '11

Dovecot 1.2.12 maildir format using :LAYOUT=fs (my Mail dir came from KDE) I can't remember the permissions of the /Mail/ directory because I haven't been concerned with it too much until now. I think they were user:user or user:mail. Now a new mail ends up 600 root:mail. (in alternate directories) When I start my mutt client to the imap server it gets an error for any folder containing a root:mail new mail file. I think the root ownership is a procmail side effect? If I chmod 760 Mail/folder/* (then the new emails show in dovecot without the access error) It appears mail comes to the INBOX fine just not individual folders On the initial access, dovecot gets a "missing +r perm" or "+x" in the log. 1: What permission structure should permeate my Mail dir? 2: What might affect the incoming mail file getting wrong permissions/ownership? I'm thinking the later may be a procmail issue unless it is related to initial incorrect permissions? Thanks for any insight. -Walt

[Dovecot] Trouble with password scheme module
by Ian R. Justman 29 Mar '11

29 Mar '11

Hi, all. About two and a half years ago, I wrote a hack to add an additional MD5-based password scheme to Dovecot, but I wrote it as a hack to src/auth/password_scheme.c since it was relatively easy to do, and I needed to get a machine running since the machine I was replacing, a Sun Ultra 5 running Post.Office, had dying hard drives. Now, I'm actually sitting down and adapting it as a module and am having trouble getting it to work. The code tarball itself can be picked up here: http://www.ian-justman.com/code/dovecot/password_scheme_po_smd5.tar.gz Before I continued, I made sure that a system-level account worked: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <username> +OK pass <password> +OK Logged in. quit +OK Logging out. Connection closed by foreign host. I then enabled the module, which introduces the password scheme "PO-SMD5". I have Dovecot's default scheme set to SMD5. If I get a password hash whose value has a {PO-SMD5} tag on it, the session looks like the following: # telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with PO-SMD5 password> +OK pass <user's password> -ERR Authentication failed. quit +OK Logging out Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:44:51 <hostname> dovecot: auth: Error: sql(<username>,<server IP>): Unknown scheme PO-SMD5 However, when I try using an account covered by the system (which does work when the plugin isn't loaded in dovecot.conf), the session looks like the following: mikuru# telnet <server IP> 110 Trying <server IP>... Connected to <server IP>. Escape character is '^]'. +OK Dovecot ready. user <user with system password> +OK pass <user's password> Connection closed by foreign host. The following entry is deposited into the system log: Mar 28 17:45:13 <hostname> dovecot: pop3: Error: dlopen(/usr/local/lib/dovecot/lib_password_scheme_po_smd5.so) failed: /usr/local/lib/dovecot/lib_password_scheme_po_smd5.so: Undefined symbol "password_scheme_unregister" Otherwise, the patch I developed under 1.x applies cleanly to 2.0.x's password_scheme.c and works perfectly as a builtin. This work was done under FreeBSD 8.1-RELEASE amd64. Any ideas? --Ian. -- Ian R. Justman UNIX hacker. Anime fan. Any questions? ianj (at) ian-justman.com
