[Dovecot] Arghh, dovecot-2 and lda

I cannot seem to get exim/lda working... In my exim log i just see these 2010-07-18 11:51:08 1OaYOJ-0003Vn-2P == brandon(a)olypen.com R=router_pop T=dovecot_deliver defer (2): No such file or directory: failed to chdir to maildir:~/maildir:INDEX=~/maildir/dovecot-index Now I have all the debugging on as far as i can tell, and exim is obviously being returned some value from dovecot because it knows about the maildir that i return from sql, but yet there is zero being logged in debug or anything else. If I run the dovecot-lda from the command line with the same then it works and i get logs entered command = /usr/local/libexec/dovecot/ -e -k -f "$sender_address" -d "$local_part@$domain" -m "$acl_m1" I am returning a home and mail with userdb, the directory does exist, owned by mail.mail...

[Dovecot] Questions about dbox (sdbox?), mdbox
by Brandon Lamb 18 Jul '10

18 Jul '10

Hello, So ive spent the last 45 minutes or so searching the list for dbox stuff, but Im not seeing anything real definitive. My question is basically whether the dbox format is ready for production environment, is sdbox or mdbox more stable/ready than the other or does it matter? What are people's experience/review with running this format (and if you reply can you tell me which one you're using). Is there any docs/wiki page for migrating from maildir -> dbox? Searching for "dbox" on the wiki only returns two results, and only one is actually for dbox. What I have (maildir format) is working, but who doesnt like shiny new toys? =P I have ~450gigs / 14k pop accounts I would have to migrate. Oh thats another question, I have seen "hybrid" throw around, can I take this to mean dbox/mdbox/both support both formats, maybe only new mail goes into the dbox stuff? And if so (or even if not) is there any way to actually convert from maildir to dbox? If anyone has any links that I cant seem to find by consulting the oracle (google) that would be fantastic =)

[Dovecot] dovecot 2.0rc2 Cannot delete a folder with Thunderbird (delete, not move to Trash)
by Sven Kirmess 17 Jul '10

17 Jul '10

With Thunderbird 3.1 I can now "delete" a folder which moves it to Trash. But I cannot remove the folder in Trash. The following is from the Thunderbird log file: 248[6814c00]: 8103800:imap.kzone.ch:A:SendData: 64 rename "test10" "Trash/test10" 248[6814c00]: 8103800:imap.kzone.ch:A:CreateNewLineFromSocket: 64 OK Rename completed. 248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:SendData: 70 delete "Trash/test10/" 248[6814c00]: 8103800:imap.kzone.ch:S-Trash/test10:CreateNewLineFromSocket: 70 NO Invalid mailbox name: Trash/test10/ I can confirm that dovecot cannot delete a folder if the name is ended with a slash. b list "Trash/x" * * LIST (\HasNoChildren) "/" "Trash/xx" * LIST (\HasNoChildren) "/" "Trash/x" b OK List completed. c delete "Trash/x" c OK Delete completed. d delete "Trash/xx/" d NO Invalid mailbox name: Trash/xx/ Let me know if that's a Thunderbird bug and I'll open a ticket with Thunderbird. (But I hope it's a dovecot bug as dovecot bugs actually get fixed, fast. :-) $ dovecot -n # 2.0.rc2: /etc/opt/dovecot/dovecot/dovecot.conf # OS: SunOS 5.10 i86pc zfs first_valid_uid = 100 mail_location = mdbox:/l/dovecot/%u/dbox passdb { driver = pam } protocols = imap service imap-login { inet_listener imap { port = 0 } } service imap { vsz_limit = 1073741824 } ssl = required ssl_cert = </etc/opt/dovecot/dovecot/certs/dovecot.pem ssl_key = </etc/opt/dovecot/dovecot/private/dovecot.pem userdb { driver = passwd } verbose_proctitle = yes

[Dovecot] mdbox expunge purge question
by Daniel Luttermann 17 Jul '10

17 Jul '10

Hi, I'm testing Dovecot 2.0rc2 with mdbox mail format and I'm not sure what this exactly means: http://wiki2.dovecot.org/MailboxFormat/dbox Quote from wiki page: ===== Expunging a message only decreases the message's refcount. The space is later freed in "purge" step. This may be done automatically within the session or later in a nightly cronjob when there's less disk I/O. ===== So this means that even if a user deletes a mail the space gets only freed if I run "doveadm purge" manually or an user requests this over his mail client? When the expunge plugin is used the deleted mails are stored in a special mailbox in the users mailbox so it's needed to use the expire plugin too if this should be done automatically? Is it recommend to run "doveadm purge" periodically if mdbox is used? Btw: when I try to run doveadm -Dv expunge -u testuser(a)dlutt.de mailbox Trash savedbefore 30d for example I get such an error: doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules doveadm(root): Debug: Module loaded: /usr/lib/dovecot/modules/lib01_acl_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib/dovecot/modules/doveadm doveadm(root): Error: dlopen(/usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so) failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_lookup doveadm(root): Error: dlopen(/usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so) failed: /usr/lib/dovecot/modules/doveadm/lib10_doveadm_quota_plugin.so: undefined symbol: quota_user_module Plugin expire or expunge is not currently enabled in Dovecot's config. Thanks for any hints. Daniel

[Dovecot] dovecot 2.0 (latest on website), client workarounds?
by Brandon Lamb 17 Jul '10

17 Jul '10

What are the current valid imap_client_workarounds and pop3_client_workarounds? I had a tb-folder one, and outlook-idle i imap, and i kept getting errors. The only one that would seem to not give an error was imap.conf: imap_client_workarounds = delay-newmail pop3.conf: pop3_client_workarounds = outlook-no-nuls oe-ns-eoh

[Dovecot] Temporary files
by Timo Sirainen 16 Jul '10

16 Jul '10

In v1.0 .. v1.1 deliver was writing incoming >128k mail to /tmp file (to avoid reading it all into memory). In v1.2 I moved it to user's home directory. This slowed deliveries for NFS users. Also people with filesystem quota had trouble since now user required twice as much available quota to save a message. The FS quota problem was "solved" by having quota-fs plugin change the default temp file path to /tmp. So why was the move made in the first place? Because a) some people had small (maybe ramfs) /tmp and Dovecot was eating it all up and b) to avoid any potential security issues with storing per-user files to a shared directory. I'm now thinking about a new setting (mail_temp_dir?) for v2.0 where these temp files would be stored (lda, lmtp, some others in future). Maybe the b) problem isn't that huge, so maybe there doesn't need to be a way to store them to user's home. So that leaves a) problem. Maybe the setting could default to /var/tmp instead of /tmp? That probably has more disk space available usually. (I hope /var/tmp is available everywhere?) Any thoughts?
