I've only experienced this with Thunderbird...maybe the "regular" berries have not configured their BIS accounts properly? The only problem I'm aware of with Blackberry devices is that if the BIS servers can't login because Dovecot is being upgraded (version mismatch), then they'll go into polling mode (no more instant emails).

Anyone has had differing experiences with different blackberries? Someone with Blackberry Gold/Bold get only 1 e-mail yet regualr blackberries get multiple copies of the same e-mials. Is this a blackberry bug or is their something I have to set in Dovecot? -- Member - Liberal International This is doctor(a)nl2k.ab.ca Ici doctor(a)nl2k.ab.ca God, Queen and country!

[Dovecot] SASL auth and proxy
by mailing＠securitylabs.it 02 Oct '10

02 Oct '10

Hello, I'm finding a way to have a pool of smtp-auth servers in front of my actuals servers to permit relay to our customers. Now users sends emails connecting to the right IP via mail.domain.tld, with authentication. Every server has it's own user database in mysql. I'd like to have a pool of server (with round robin, ideally with postfix + sasl + dovecot) that authenticate the users with the actuals servers and then pointing mail.domain.tld to this pool and not to one server. My trouble is how to authenticate users. Can I use: http://wiki.dovecot.org/Authentication/MultipleDatabases to tell Dovecot to authenticate with every MySQL database on the servers "behind"? If yes, is there a better way to do this considering I'm already using some proxy machines (dovecot) for pop3/imap and so I already have a db with domain.tld -> IP of the server? I also have some machine without a MySQL DB for users (vpopmail + cdb), so the option with MultipleDatabases will be good only for some machines. Something similar to the proxy mechanism that I already use for pop3/imsp will be good: the proxy connect to the machine behind that do the authentication, I only need a table with domain -> server IP (that I already have). Thanks for any advice.

[Dovecot] Dovecot v0.99.13-3 upgrade to 1.0.15-2 ??
by cajun 02 Oct '10

02 Oct '10

I've read some of the mailing lists looking for information on this. Thus far, about all I've found is there was a complete rewrite of Dovecot some time back. I'm wondering now is it even possible to use the same mbox's from 0.99.13-3 with version 1.0.15-2? Is there a procedure documented somewhere? Any pointers would be much appreciated.

[Dovecot] dovecot 2.04 broke folder sharing
by Robert Schetterer 02 Oct '10

02 Oct '10

Hi Timo, upgrading from 2.03 to 2.04 broke folder sharing at my setup double checked this with tests reverting versions etc setting acl and subcriptions are working with 2.04, but in difference to 2.03 no shared subfolder is created at acl/subscription set time so subscribing afterwards fail with ignore message by bad subscription the mails store is on drbd with ocfs2 i didnt change any other config parameter during the tests so some patch must have changed folder sharing behavior from 2.03 to 2.04 speculate something with default hardlinks etc? any idea ? -- Best Regards MfG Robert Schetterer Germany/Munich/Bavaria

[Dovecot] ACL handling bugs in v1.2.8+ and v2.0
by Timo Sirainen 02 Oct '10

02 Oct '10

I thought I'd write one mail about this, rather than duplicate the whole thing to both v1.2.15 and v2.0.5 release announcements. So, ever since this commit: 2009-11-10 Timo Sirainen <tss(a)iki.fi> * src/plugins/acl/acl-backend-vfile.c: acl: Merge group rights if user belongs to more than one. [76ff6831c9ae] The ACLs were being merged, rather than fully replaced, a bit too often. Since this is about merging, the problem could have happened only when using more than one entry in the ACL file. The main problems created by this were: a) If admin wanted to remove some rights from mailboxes in user's private namespace (e.g. symlinked shared mailboxes), they may not have gotten removed. b) When mixing up multiple ACL entries, such as groups/users the more specific entry may not have replaced the previous entry (e.g. group-override may not have worked as expected). The bug happened when two or more ACL entries of same "type" existed. The first entry was handled correctly, but the next ones may have only been adding ACLs rather than replacing them. For example if you had the following ACL file: group=people lrwi user=foo lr user=bar lr So basically everyone in "people" group should have "lrwi" rights, but foo and bar users should have only "lr" rights. If foo and bar didn't belong to people group, everything would work as expected. If they did, then what would happen is: * foo would work correctly, because it was the first entry of user type. * bar would keep "lrwi" rights, because the previous entry (user=foo) was of the same type (both are "user" type), so Dovecot decided to add the rights on top of group=people entry rather than replace them. BTW. The other ACL bug/"feature" of automatically adding admin rights that was fixed in v1.2.15 was already fixed in v2.0.beta2.

[Dovecot] Outlook 2010 Delayed Emails
by Munroe Sollog 02 Oct '10

02 Oct '10

dovecot --version = 1.2.11 dovecot -n: http://pastebin.com/ahCpdC0F I have a user that has no problem viewing email from roundcube (webmail) but Outlook 2010 doesn't seem to download random messages for a day or two, then they suddently show up. I saw the wiki had some suggestions for older versions of Outlook to fix other problems, but I didn't really see anything like this. Any help would be appreciated.

[Dovecot] zlib plugin weirdness
by Kyle Wheeler 01 Oct '10

01 Oct '10

Hello, I'm trying to get the zlib plugin working on my 2.0 server. I started with an mbox that Dovecot can read just fine. Then I gzipped it, and now Dovecot complains that it's corrupted: Error: Next message unexpectedly corrupted in mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz at 1907 Error: Unexpectedly lost From-line from mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz at 1907 Error: zlib.read(/var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Int…: unexpected EOF at 1765954 Error: i_stream_get_size() failed with mbox file /var/lib/vpopmail/domains/memoryhole.net/kyle/Maildir/Archive/Intellego.gz: No such file or directory A similar thing happens when I bzip it. I was worried that it wasn't even using the zlib plugin, but since it makes reference to zlib.read, I assume that it is. Does anyone know what might be going wrong? ~Kyle -- The only way to oppose a bad idea is to replace it with a good idea. -- Jack Kemp

[Dovecot] LMTP don't accept jobs for system users
by Alejandro Maurich 01 Oct '10

01 Oct '10

Hi, I'm trying to configure Dovecot 2.0.1 to deliver email to users in /etc/passwd using the Dovecot LMTP service. So far, I can sucessufully do POP3 for system users, but when Postfix tries to deliver email to the Dovecot LMTP service the LMTP reject the job with: "User doesn't exist ale(a)centos54.mydomain.com" Any suggestions? The user 'ale' is a valid user: # grep ale /etc/passwd ale:x:500:500:Alex:/home/ale:/sbin/nologin This is the dovecot -n output: # 2.0.1: /etc/dovecot/dovecot.conf # OS: Linux 2.6.18-164.el5xen i686 CentOS release 5.4 (Final) disable_plaintext_auth = no mail_location = maildir:~/Maildir mail_privileged_group = mail mbox_write_locks = fcntl passdb { args = session=yes failure_show_msg=yes dovecot driver = pam } service lmtp { inet_listener lmtp { address = 127.0.0.1 port = 10050 } unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl_cert = </etc/pki/dovecot/certs/dovecot.pem ssl_key = </etc/pki/dovecot/private/dovecot.pem userdb { driver = passwd } protocol lmtp { mail_plugins = $mail_plugins }

[Dovecot] IMAP connection timeout value?
by Tamas Kadar 01 Oct '10

01 Oct '10

So we're having some ISP issues lately, meaning we have to reboot our cable modem like 2-3 times a day. An unfortunate side-effect I've found is, once the users max out their connection limit (which I've set to 10, and many people do), if we reboot the cable modem, they can't log in cause their connections get 'stuck' until I `doveadm kick` them, or wait for the connections to timeout which takes ??? minutes. Can I adjust that value to something like 30 seconds? Thanks and best regards, KT
