[Dovecot] Dovecot LDA and quota
by Jonas Christian 25 Sep '08

25 Sep '08

Hi List, I recently upgraded to Dovecot 1.1.3 on FreeBSD and got into trouble over the quotas. We implemented per-user quotas using plugin { quota = maildir } and protocol lda { mail_plugins = quota } We use a passwd-file userdb with extra fields, which used to be quota=maildir:storage:<bytes> which I changed to quota_rule=*:bytes:<bytes> What happens now is that deliver (the Dovecot LDA) only picks up the quotas set in the maildirsize file in the user's homedir. It doesn't pick up the quota set in the userdb. Also, when I delete the maildirsize file, I doesn't get recreated by the LDA and quotas don't get checked at all. Any ideas? I'd be very grateful for any pointers. Cheers, Jonas

[Dovecot] Using deliver with postfix
by Rich Winkel 25 Sep '08

25 Sep '08

Hi, I'm trying to set up dovecot 1.1.2 and postfix 2.5.4 on freebsd 7.0. I'm getting permissions problems on auth-master and I'm not sure of the correct settings to use. In postfix's main.cf I have mailbox_command=/usr/local/libexec/dovecot/deliver -d $USER In dovecot.conf I have: socket listen { master { path = /var/run/dovecot/auth-master mode = 0660 user = dovecot group = postfix } ... # ls -l /var/run/dovecot/auth-master srw-rw---- 1 dovecot postfix 0 Sep 18 18:26 /var/run/dovecot/auth-master= In maillog I'm getting: deliver(sumbuddy): Can't connect to auth server at /var/run/dovecot//auth-master: Permission denied (I'm not sure where it's getting the "//" in the path either ...) Also I'm confused about whether I need the postfix options: maildrop_destination_recipient_limit=1 dovecot_destination_concurrency_limit=1 or even whether these are current options in my version of postfix (they don't appear in main.cf.default) Does deliver require such limits on concurrency or # of recipients? Thanks!! Rich

I'd suggest trying first with another client to see if it's not an issue with Thunderbird, which in my opinion is not very good at handling attachments in imap.

[Dovecot] Dovecot 1.1.3 upgrade
by CJ Keist 24 Sep '08

24 Sep '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I planning to upgrade from 1.1.2 dovecot to 1.1.3, that is if most people feel the 1.1.3 is more stable now than 1.1.2? I've downloaded the code and been going through and applying all the changes listed at the URL below: feed://hg.dovecot.org/dovecot-1.1/rss-log I gotten all of the applied except for the AIX one, I'm running on solaris. The last patch I'm not able to figure out: http://hg.dovecot.org/dovecot-1.1/rev/04fdaa2f831e I'm able to apply the fist patch in the file but the second doesn't look anything like I have in the file. Here is what my file looks like beginning at line 237 in src/lib-mail/message-address.c /* from now on don't return -1 even if there are problems, so hat the caller knows this is a group */ ctx->parser.data++; (void)rfc822_skip_lwsp(&ctx->parser); ctx->addr.mailbox = p_strdup(ctx->pool, str_c(ctx->str)); add_address(ctx); if (parse_mailbox_list(ctx) > 0) { if (*ctx->parser.data == ';') { ctx->parser.data++; (void)rfc822_skip_lwsp(&ctx->parser); } } add_address(ctx); return 1; } Can you show me how this section of the code should look like?

[Dovecot] [Dovecot 1.1.3] Strange problem with attachment download
by Thomas Gropp 24 Sep '08

24 Sep '08

Hello everyone, I am testing Dovecot 1.1.3 at the moment to see if I can migrate from UW-Imap(mbox) to Dovecot(maildir). Because I dont' want to influence the production server I installed Dovecot on an ununsed computer with some dummy-testusers using ssl and maildir. Installation was without any problems and everything works fine with one exception: I cannot download some attachments. If the attachment is a simple textfile or bitmap it's ok, but everything else (pdf, zip, etc. - size doesn't matter) does not work. Here is what happens: 1) I right-click on the attached file -> "save as" (using Thunderbird 2) 2) I choose a target dir (no matter if local disk or nfs) 3) the download-dialog pops up and says: "starting...." 4) nothing happens form then on In the log file I see (lots of them for a single "attachment-download-try" until I stop Thunderbird): "dovecot: Fatal: IMAP(<username>): io_loop_handle_add: epoll_ctl(1, 1): File exists" (which file??) I googled this message but without success. I already tried having all files on the local fs instead of nfs but it doesn't change anything. I also tried a lot of different settings (concerning locking, nfs, permissions) in the dovecot.conf. Everything else works just fine: logging in, receiving, creating folders, deleting etc...) Im using a (very) old SuSE 9.0 installation with ext2. I put my (current) devecot.conf and the output of "dovecot -n" at the end. As I have no idea what else to try/check: Anyone out there who has a tip what else I could check to solve this? Or even someone who had the same problem with a solution? ;o) Thx Thomas my current dovecot.conf: ************************************************************* protocols = imaps protocol imap { listen = *:143 # not active ssl_listen = *:446 # for testing } listen = * disable_plaintext_auth = yes ssl_disable = no ssl_cert_file = /etc/ssl/certs/imapd.pem ssl_key_file = /etc/ssl/certs/imapd.pem verbose_ssl = yes login_greeting = Dovecot ready. mail_location = maildir:~/Maildir mmap_disable = yes fsync_disable = no mail_nfs_index = yes lock_method = dotlock maildir_copy_with_hardlinks = yes mbox_read_locks = dotlock_try mbox_write_locks = dotlock_try mbox_dotlock_change_timeout = 120 protocol imap { } protocol pop3 { } protocol lda { postmaster_address = postmaster(a)example.com } auth_debug = yes auth default { mechanisms = plain passdb shadow { } userdb passwd { } user = root } dict { } plugin { } ************************************************************* Output of dovecot -n ************************************************************* # 1.1.3: /usr/local/etc/dovecot.conf protocols: imaps ssl_listen: *:446 ssl_cert_file: /etc/ssl/certs/imapd.pem ssl_key_file: /etc/ssl/certs/imapd.pem verbose_ssl: yes login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login mail_location: maildir:~/Maildir mail_debug: yes mmap_disable: yes mail_nfs_index: yes lock_method: dotlock mbox_read_locks: dotlock_try mbox_write_locks: dotlock_try auth default: debug: yes passdb: driver: shadow userdb: driver: passwd ***************************************************************+

[Dovecot] fts squat and dovecot-shared
by Anton Yuzhaninov 24 Sep '08

24 Sep '08

It seems, that dovecot-shared ignored by fts squat and dovecot.index.search/dovecot.index.search.uids created with wrong permissions. This makes squat unusable with symlinked shared maildirs. -- WBR, Anton Yuzhaninov

[Dovecot] Can't move mail items to Inbox
by Phillip Smith 24 Sep '08

24 Sep '08

Hi all, Trying to setup Postfix / Dovecot / Fetchmail to collect all my mail centrally on my home server and serve it out by IMAP. Everything is working, using Maildir format except I can't move mail from a sub-folder to my Inbox. Example: I send a test message to myself. It gets picked up by fetchmail, and delivered to /home/user/Maildir/new by postfix. Dovecot serves that out to my client. I can then move that message from the Inbox to a subfolder, but then I can't move it back to the Inbox. I don't get any error messages or anything - it just doesn't happen :( Any help and advice would be great. root ~ # dovecot -n # 1.1.3: /etc/dovecot/dovecot.conf listen: 192.168.31.3 disable_plaintext_auth: no login_dir: /usr/var/run/dovecot/login login_executable: /usr/libexec/dovecot/imap-login login_greeting: Dovecot server.local READY login_max_processes_count: 8 mail_location: maildir:~/Maildir auth default: passdb: driver: pam userdb: driver: passwd root ~ # dovecot --version 1.1.3 Cheers, ~p

[Dovecot] One fs with quota, one without: incorrect data shown
by Laurent Blume 24 Sep '08

24 Sep '08

Hello all, I'm using Dovecot 1.0.15 on a Solaris 10. There are two different FS in place for IMAP: /var/mail for inbox /export/home for the mail folders The first doesn't have quota, the second does. However, I've noticed that Thunderbird does display quota information on the inbox (that doesn't make any sense, the values are incorrect). The same incorrect values are shown for folders as well. I tried the following configurations, but without success, the result is always the same: quota = fs ---- quota = fs:INBOX:mount=/var/mail quota2 = fs:Others:mount=/export/home ---- quota = fs:Others:mount=/export/home Any idea what I'm doing wrong?

[Dovecot] Debugging password schemes
by Ian R. Justman 23 Sep '08

23 Sep '08

Hi, all. I managed to get my new password scheme routine written, but a couple of things: 1. The example module lacks an init routine. Since I used it as a model, my module also lacks one. As such, my newly-built module is seen but not registered. In the meantime, I moved the routines into password-scheme.c instead where I had access to all the MD5 routines already set up for me. 2. Once in password-scheme.c and modified to the point where it builds without warnings or errors and it doesn't gag on itself, it doesn't seem to work properly. What's the best way to debug password-scheme.c so I can see what's going on so I can fix things accordingly? I have to "manually" break apart the value stored in a database a bit differently than other salted values (it's using salted MD5 values a bit differently than normal). The password format from a Post.Office server, but apparently, Netscape Messaging Server uses this same format. Thanks! --Ian. -- Ian R. Justman UNIX hacker. Anime fan.
