[Dovecot] mdbox, mdbox_rotate_size 2m default
by Brandon Lamb 19 Jul '10

19 Jul '10

Anyone else test using different values? Was 2M chosen as a default based on anything specific? Is there any kind of known range where performance starts to go downhill if its greater than x or less than y? Im curious if there would be any obvious reason why I shouldnt set it to 5-10 megs

[Dovecot] users can not login
by Daminto Lie 19 Jul '10

19 Jul '10

Hi, I was wondering if I could get some help here. Recently, I decided I want to move from Windows XP Pro OS to a Linux OS such as Ubuntu. I am new to Linux OS but willing to learn. I have installed Ubuntu Server 10.04, Apache2, MySQL5, PHPMyAdmin, Postfix, DoveCot and Squirrelmail on my server. I have checked them all and they are all up and running at the moment. Now, what I am trying to do here is to add a couple of users and see whether they can login to squirrelmail. The result is none of those two users are able to login. I went to check the mail.log and the error message is as follows Ubuntu-MailServer dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<david.keith>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured My silly question is I do not quite understand what the above error means. How do i enable users to login and test to see if they can send and receive emails. Users can login via squirrelmail. Any help would be greatly appreciated.

[Dovecot] pam needs root with 2.0rc2 on Solaris?
by Laurent Blume 19 Jul '10

19 Jul '10

Hello all, I have a question using PAM to authenticate on Solaris 10, with 2.0rc2. I need to set the user for auth-worker to root, else it will return "Unknown user". Is that expected? I'm using PAM, so why does it need access to /etc/shadow? TIA! Laurent service auth-worker { # Auth worker process is run as root by default, so that it can access # /etc/shadow. If this isn't necessary, the user should be changed to # $default_internal_user. user = root #user = dovecot } Jul 18 09:59:31 tiphaine dovecot: [ID 583609 mail.info] auth: pam(user,127.0.0.1): unknown user

[Dovecot] Arghh, dovecot-2 and lda
by Brandon Lamb 18 Jul '10

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.

[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
