[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?

[Dovecot] Ok, I've given up
by Chuck McManis 15 Jul '10

15 Jul '10

Sigh, In the interest of moving forward on this project I've given up trying to get Dovecot to support mailboxes, rather I've tweaked around in qmail and had it deliver into a mail directory on a disk, that isn't NFS mounted. That got me past the various locking complaints and "operation not supported" on home directories that were mounted from the NetApp filer. Going as vanilla as possible I've managed to both send an email that qmail delivered and fetch the email with my 3 test clients (Eudora, Thunderbird, and Evolution) (I know they are, in a sense, all variations on a theme but MUA monoculture seems to be inevitable these days). So a few questions for the other esteemed system operators here if you know the answer I'd love to hear it. Question 1) Are my user's passwords safe from prying eyes? First, part of this effort was to move off of an APOP infrastructure into something more secure against password eavesdropping. To that end I've configured Dovecot with simply: protocols = pop3 service pop3-login { inet_listener pop3s { port = 995 ssl = yes } } Note that there is NO port = 110 listener and yet Dovecot seems to listen there anyway. My question, can I be sure that it is not accepting non-SSL based connections? Attempts to use plaintext on 110 were rebuffed so that seems to be the case. My intent is that if my user is using this in an airport they won't give away their email password to a bad guy who is sniffing all the packets. Question 2) Is there any way to run dovecot from tcpserver ? One of the things I like is the program tcpserver. I like it because I can simply "not allow" large chunks of the internet to connect at all to certain ports. (I use this for SSH in particular since all the kids love throwing dictionary attacks around). I'd like to give my POP3 ports equivalent protection. I also like the logging facilities of the supervise / multilog service. To use this I'd need Dovecot to accept the connection handed to it, and not do the whole setsid daemon thing since tcpserver will start another one if needed. I can send the logging out to stderr (thanks!) and get the logging stuff but still wondering about the 'hand you a connection.' --Chuck
