[Dovecot] Exim+dovecot and quota check in exim's ACL before real message routing.
by Anton 26 Sep '08

26 Sep '08

Good day. I want to migrate from cyrus-imap to dovecot but I can not find replacement of one feauture presented in the cyrus-imap. It is LMTP. All mail users are virtual and mail works like: username(a)real-domain.com -> anotherusername(a)fake-domain.local. I whould like to check "delivery is possable" in the exim's ACL. In the exim+cirus scheme I use Callout verification from exim to cyrus and if user's quota is exeeded callout returns fail and exim does not take message for queueing. Dovecot has no LMTP and I see no possability to do such callouts. I tried to turn on quotas in the dovecot. Message was taken by the exim placed into exim's queue but cannot be delivered to dovecot with "local_delivery transport output: Quota exceeded" and message stays in queue for a long time. Is any possability to chech quota usage in the exim's ACL befor taking message body ? -- Anton [WARM-RIPE] Stack ltd division head tel. 8 (3822) 555-797

[Dovecot] Problem when just .dovecot.sieve symlinks changes
by Steffen Kaiser 26 Sep '08

26 Sep '08

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello, well, I'm sort of sure that this was raised in the past, but I do not find the patch / answer of it: I'm running dovecot v1.0.15 from hg (5567:568687e4df02) with managesieve patch v9.2 (there is one change between this and v9.3 except in regards of AUTH so this should not matter.) and dovecot-sieve v1.0.3. When an user issues just "SETACTIVE" in order to activate an _old_ script, deliver does not rebuilt the compiled file. If I peeked the correct code, CMU sieve just stat()s both .dovecot.sieve and .dovecot.sievec, but misses the fact that the symlink's .dovecot.sieve, which is used by the managesieve patch, time is newer. Actually I dimmly remember that the issue was solved somehow, but I did not found how when searching the archives. Shall deliver lstat(.dovecot.sieve) or shall managesieve delete the cache file?

[Dovecot] patch for passdb-vpopmail in v1.1.3
by James Fidell 25 Sep '08

I need pop-before-smtp to work with vpopmail (yes, yes, I know, don't ask).

[Dovecot] auth(default): vmysql: sql error[3]: MySQL server has gone away
by Jordi Prats 25 Sep '08

25 Sep '08

Hi all, I'm facing this error: dovecot: auth(default): vmysql: sql error[3]: MySQL server has gone away I've been reading this list archives and seems to be a resolved issue (back to 2005), so dovecot should just reconnect but it does not so. I'm using dovecot 1.1.3 with vpopmail 5.4.25 with this configuration: # 1.1.3: /usr/local/etc/dovecot.conf listen: *:143 ssl_disable: yes disable_plaintext_auth: no login_dir: /usr/local/var/run/dovecot/login login_executable: /usr/local/libexec/dovecot/imap-login verbose_proctitle: yes first_valid_uid: 89 last_valid_uid: 89 mail_location: maildir:/home/vpopmail/domains/%d/%n/Maildir auth default: passdb: driver: vpopmail userdb: driver: vpopmail Any ideas? Thanks you! -- Jordi

[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
