[Dovecot] Errors on mbox to Maildir conversion
by Phill Edwards 17 Mar '09

17 Mar '09

I have Julian Fitzell's migrateuser.sh script which uses mb2md-3.20.pl to convert a mailbox in mbox format to Maildir. I have set up a test user called "mailtest" which has mail as follows: /var/mail/mailtest /home/mailtest/mail/ Drafts MoreStuff Sent Items Stuff After the conversion I want all this user's mail to be in /home/mailtest/Maildir/ I'm not quite sure how to run the migrateuser.sh script, but I think it's like this (run as user mailtest): $ /usr/local/bin/mb2md/migrateuser.sh mailtest /home/mailtest /home/mailtest/Maildir When I run this I get the following output: mailtest -- Migrating INBOX... Converting /var/mail/mailtest to maildir: /home/mailtest/Maildir.mdwork.1237291760 Source Mbox is /var/mail/mailtest Target Maildir is /home/mailtest/Maildir.mdwork.1237291760 Created UID list: /home/mailtest/Maildir.mdwork.1237291760/dovecot-uidlist 3 messages. warning: Can't open /home/mailtest/Maildir.mdwork.1237291760: not a selectable mailbox [ERROR] (mismatch during post compare) mailtest -- 0 new message(s) (), 3 total mailtest -- That bit about "not a selectable mailbox" seems to be the problem. Any idea what I'm doing wrong here? Regards, Phill

by Muhammed Alat 17 Mar '09

17 Mar '09

Hi, im a newbee using dovecot. I want to use checkpassword, but i've no idea how to use it. DoveCot is running and checking the passwords with a ldap server. But in future we want to use a sql database, where the password and userinformation is stored. I want to use checkpassword, to authetificate the users with the passwords. But ive no idea how a script for checkpassword can be. What should i write to the checkpassword file (actualy the file is empty). The SQL Database is on another server. Can i use PHP for checkpassword, and if i can, how should it be written. Which variables can i use and what and how shoul i return the result? Greetings, Muhammed

by Harry Lachanas 16 Mar '09

16 Mar '09

Hi, I am on dovecot 1.1.11 trying to figure out the expire tool .... The thing is that when I had confed the exp tool there where a bunch of mails inside the mail boxes. Thus it seems as if the database is not updated about them. Is there a way to update it from command line to include the old mails ??? Thanks Harry

[Dovecot] folders are not under INBOX
by Ondrej Svoboda 16 Mar '09

16 Mar '09

hi guys, I hope it's common trouble, but I'm not able to find a solution: - i'am using courier imap and trying to migrate to the dovecot - on courier I have all folders as subfolder of Inbox - i.e. Inbox.Sent but on dovecot the folder Sent is not subfolder of Inbox, but its on the same level. Please is there some possibility to have the subfolders the same behaviour as in courier? we have lot's of customers so after the upgrade the folders can't change. thank you ondrej

[Dovecot] Dovecot and high availability
by d dimov 16 Mar '09

16 Mar '09

Hello dear all. Please accept apologies if the topic was discussed already, tried searching the archives but found few details. What I am looking for would be the best way to making Dovecot highly available in an environment where: two Alteons are load-balancing two Dovecot servers, each Alteon seing both of them; the clients are using exclusively POP3; low volume; in case of a Dovecot server failure service should fail over to the other node with preferably no manual intervention. Failover could mean Alteons just ignoring the failed host and routing all requests to the healthy one. Would it be shared NFS volume mounted on both of the servers from some NAS, maildirs put on that volume and both Dovecots seing the mailboxes simultaneously? Any risks? Is there a good document describing such a setup? Thank you in advance and please indicate if I missed relevant details. Best regards, Dimov

[Dovecot] Mailing list convert scripts not working on wiki
by Phill Edwards 16 Mar '09

16 Mar '09

I'm trying to download Julian Fitzell's scripts to convert mbox to Maildir format from the wiki page at http://wiki.dovecot.org/Migration/MailFormat But when I click on the links for the scripts it just sends me back to the same page rather than downloading the scripts. The links in question are http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… and http://wiki.dovecot.org/Migration/MailFormat?action=AttachFile&do=get&targe… How can I get the scripts? Regards, Phill

[Dovecot] fstat(mboxname.lock) failed: Bad file descriptor
by Mark Sapiro 15 Mar '09

I have just upgraded from 1.2.beta1 to 1.2.beta2. My configuration is: [root@sbh16 ~]# dovecot -n # 1.2.beta2: /usr/local/etc/dovecot.conf # OS: Linux 2.6.18-8.1.14.el5 i686 CentOS release 5 (Final) protocols: pop3 pop3s imap imaps ssl_cert_file: /etc/postfix/sbh16-cert.pem ssl_key_file: /etc/postfix/sbh16-key.pem login_dir: /usr/local/var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login mail_privileged_group: mail mail_location: mbox:~/Mail:INBOX=/var/spool/mail/%u mbox_write_locks: fcntl dotlock mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 pop3_lock_session(default): no pop3_lock_session(imap): no pop3_lock_session(pop3): yes auth default: mechanisms: plain apop login worker_max_count: 5 passdb: driver: passwd-file args: /usr/local/etc/dovecot.passwd passdb: driver: pam userdb: driver: passwd socket: type: listen client: path: /var/spool/postfix/private/auth mode: 432 user: postfix group: postfix [root@sbh16 ~]# This represents one change from the previous config. Previously with pop3_lock_session = yes, I needed mail_access_group = mail. With the upgrade to beta2, I changed that to mail_privileged_group = mail as shown above. Now, during a session lasting several seconds, I see the following in maillog: Mar 15 09:35:51 sbh16 dovecot: pop3-login: Login: user=<mark>, method=APOP, rip=68.183.193.239, lip=72.52.113.16, TLS Mar 15 09:36:01 sbh16 dovecot: POP3(mark): fstat(mark.lock) failed: Bad file descriptor Mar 15 09:36:04 sbh16 dovecot: POP3(mark): Disconnected: Logged out top=0/0, retr=1/1919972, del=0/328, size=5381253 Mar 15 09:36:04 sbh16 dovecot: child 9023 (pop3) killed with signal 11 (core dumps disabled) This does not occur with shorter sessions lasting only a few seconds or less. The only symptom is the log messages. The client sees nothing unusual, at least in this case where the session is a retrieval of one large message. I haven't tried long sessions retrieving multiple messages. If I remove pop3_lock_session = yes, the issue does not occur. I don't think I need it. I put it in a long time ago to attempt to solve a problem that was actually caused by something else. Since removing it does seem to avoid this issue, I will leave it out, but I'm reporting this anyway as it seems there may be some underlying problem. -- Mark Sapiro <mark(a)msapiro.net> The highway is for gamblers, San Francisco Bay Area, California better use your sense - B.
