[Dovecot] Maildir filename has wrong S value
by Wouter de Geus 09 Jun '12

09 Jun '12

Hello folks, This morning I tried to open an old archive mail folder using Mutt. However, while fetching headers it aborted. Checking the dovecot log gave me this: @400000004fb21996267d37d4 imap(benv): Error: Cached message size smaller than expected (9115 < 9420) @400000004fb21996267e8bac imap(benv): Error: Maildir filename has wrong S value, renamed the file from /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9115:2,S to /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1260395566.28175.black,S=9420:2,S @400000004fb21996267e937c imap(benv): Error: Corrupted index cache file /home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/dovecot.index.cache: Broken physical size for mail UID 294 @400000004fb21996267eaaec imap(benv): Error: read(/home/vpopmail/domains/benv.junerules.com/benv/Maildir/.Old.2009/cur/1… failed: Input/output error (uid=294) @400000004fb219962680683c imap(benv): Info: Disconnected: Internal error occurred. Refer to server log for more information. [2012-05-15 10:53:32] in=6503 out=192718 I've retried opening this folder several times, but each time Dovecot only fixes 1 file and then aborts. (the folder apparently has a lot more files with incorrect sizes). My question here is: Why does dovecot abort? Isn't the issue fixed after the rename? Also: The files are not corrupted or unreadable, reading them through the commandline works fine. I've looked through my backups and saw that at least half a year ago this mismatch in size was already present. I've been running dovecot for quite a while, so the cause of this size mismatch might very well be a issue in an older version of dovecot / my configuration. Right now I'm running dovecot 2.1.6, but I've been running the v1.2 version for quite a while before that. Is this something that can be improved in dovecot so it doesn't abort after 1 rename? (of course I could script a rename operation, but that seems like a workaround to me) Thanks for reading. Wouter.

[Dovecot] 2.1.7 altmove not working
by Alex Crow 09 Jun '12

09 Jun '12

Hi list, I've just set up a 2.1.7 server, and have migrated a couple of accounts across from a 2.0.15 server, keeping the old configs. I have a strange problem on the new box in that altmove just doesn't work. I have my main storage under /home/email, indexes under /home/indexes and ALT under /home/email_archive. When I run the altmove command, the following broken symlink is created in /home/email/integrafin.co.uk/acrow: lrwxrwxrwx. 1 email email 54 Jun 8 10:46 dbox-alt-root -> /home/email_archive/integrafin.co.uk/a/acrow/mailboxes But nothing is created in the archive other than the empty directory: /home/email_archive/integrafin.co.uk/a/acrow. My mail_location is: mail_location = mdbox:/home/email/%d/%n:INDEX=/home/indexes/%d/%1n/%n:ALT=/home/email_archive/%d/%1n/%n This worked perfectly on the older server. I have attached my doveconf -a output. Any help much appreciated. Regards Alex

Maybe someone is brute forcing your server's Postfix authenticated SMTP service since Postfix can be configured to use Dovecot's SASL authentication framework. Joseph Tam <jtam.home(a)gmail.com>

Hello! I want to upgrade the docevot-installation from v 1.0.5 to 2.1..7 Now I get the following executing doveconf -n -c /etc/dovecot/dovecot.conf > /home/mail1/dovecot-2.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:217: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:219: passdb passwd-file {} has been replaced by passdb { driver=passwd-file } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:222: userdb passwd-file {} has been replaced by userdb { driver=passwd-file } The section at line 217 looks like this: auth default { mechanisms = plain passdb passwd-file { args = /etc/dovecot/passwd } userdb passwd-file { args = /etc/dovecot/passwd } How do I change it to fullfill the new needs? And how do I handle line 217? add auth_ prefix to all settings inside auth {} and remove the auth {} section completely ? Thanks for help! Andreas
