[Dovecot] Configuring for virtual users in Postfix
by Jerry 03 Oct '09

03 Oct '09

FreeBSD-7.2 with Postfix-2.7x OK, this is my first attempt to configure Dovecot using Postfix and virtual users. In the LDA.Postfix.txt file, there is a reference to making the following setting: dovecot_destination_recipient_limit = 1 virtual_mailbox_domains = your.domain.here virtual_transport = dovecot However, Postfix does not recognize the dovecot_destination_recipient_limit = 1 setting. There is a "virtual_destination_recipient_limit =" setting in Postfix. Is that the setting that I should tweak? -- Jerry gesbbb(a)yahoo.com There is no TRUTH. There is no REALITY. There is no CONSISTENCY. There are no ABSOLUTE STATEMENTS. I'm very probably wrong.

[Dovecot] Mailbox locking problem with iphone and POP3
by Bill Dunn - VCI Internet Services 03 Oct '09

03 Oct '09

I have a problem I can't seem to fix. I have dovecot configured to do POP3 with plain text authentication using a MySQL database. I am using Dovecot 1.0.7 with fcntl locking. My problem has been when an iPhone/iPod checks email. The iPhone/iPod doesn't disconnect with a TCP FIN packet and it leaves the mailbox in a locked state and prevents the user's desktop from checking email. I have tried changing the file locking method and other config file options without any luck. Oddly, I am using the last version of cucipop on another server with fcntl and lockf file locking and it doesn't have this problem. If someone could clue me in I'd be very grateful. Bill

[Dovecot] IMAP proxying for ALL users to internal mail server
by Vitaliy Vladimirovich 02 Oct '09

02 Oct '09

Hi! How must I adjust Dovecot for proxying all users from the Internet to the internal Exchange Mail Server? This is my config files (most important): dovecot.conf protocol imap { #listen = *:10143 ssl_listen = 194.0.148.10:993 auth default { mechanisms = plain login passdb passwd-file { args = /usr/local/etc/dovecot-%Ls.conf } } dovecot-imap.conf testmail1@example.org::0:0::::proxy host=10.0.10.3 port=143 nopassword With this configurations all works fine, but if I trying change dovecot-imap.conf as below %n@%d::0:0::::proxy host=10.0.10.3 port=143 nopassword I get an error: Oct 2 15:10:58 relay dovecot: auth(default): client in: AUTH 1 PLAIN service=imap secured lip=199.10.149.10 rip=199.10.149.3 lport=993 rport=28316 resp=<hidden> Oct 2 15:10:58 relay dovecot: auth(default): passwd-file(testmail1(a)example.org,199.10.149.3): lookup: user=testmail1(a)example.org file=/usr/local/etc/dovecot-imap.conf Oct 2 15:10:58 relay dovecot: auth(default): passwd-file(testmail1(a)example.org,199.10.149.3): unknown user Oct 2 15:10:59 relay dovecot: auth(default): new auth connection: pid=62532 Oct 2 15:11:00 relay dovecot: auth(default): client out: FAIL 1 user=testmail1(a)example.org Any ideas??

[Dovecot] Problem with local pine after upgrade to 1.2.5
by Gerhard Wiesinger 02 Oct '09

02 Oct '09

Hello, I upgraded from dovecot 1.1.17 to 1.2.5. Works well so far with e.g. Thunderbird and SSL. One problem left: pine doesn't work any more with rsh: cat .pinerc (filtered): rsh-path= rsh-command=/usr/sbin/dovecot --exec-mail imap Starting pine: 1.) Opening INBOX 2.) [>SECURITY PROBLEM: insecure server advertised AUTH=PLAIN<] 3.) Afterwards I'm asked for a password: HOST: localhost (INSECURE) ENTER LOGIN NAME [user] : 3.) cancel: [IMAP protocol error: Authentication aborted by client.] Config: no changes at all. Any ideas why this is broken? Thnx. Ciao, Gerhard

[Dovecot] Folder Management Dovecot >1.2
by Carlos Candeias 02 Oct '09

02 Oct '09

Regardless of the mail client no user can modify, move, delete or subscribe an imap folder with Dovecot >1.2.1 (meanwhile 1.2.5). Dovecot apparently have some dotlock problems: (From dovecot.log) Oct 02 14:58:19 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:19 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:20 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:20 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted Oct 02 14:58:21 IMAP(jcci): Error: fchown(/candeias/home/jcci/.mail/Maildir/subscriptions.lock, -1, 0(root)) failed: Operation not permitted (egid=1003(management), group based on /candeias/home/jcci/.mail/Maildir) Oct 02 14:58:21 IMAP(jcci): Error: file_dotlock_open() failed with subscription file /candeias/home/jcci/.mail/Maildir/subscriptions: Operation not permitted This was an attemt of changing a subscription. Another weird point: I can create an IMAP folder although it does not show up in the folder list. But the new folder is in the subscription list, just marked as unsubscribed and there is no way to change that. This problem is safely reproducible and I wonder whether I should be really the only person having this trouble. I'm using MAILDIR and simple plain test authentification (internal mail server). The location is mail_location: maildir:~/.mail/Maildir which means a subfolder in each user's home directory. All homes are exported to NFS, but the Dovecot is just on the same server and thus accesses locally. Downgrade to version 1.1.17 solves all problems. Archlinux x86_64, Linux 2.6.30 It would be really great if somebody could understand the cause and suggest a solution!

[Dovecot] Problem with LSUB and public namespace
by Julien Danjou 02 Oct '09

02 Oct '09

Hi, I'd like to know if the following is normal. I've a setup with 2 namespace (private/public) where each user can use subscriptions. This problem is triggered by claws-mail, which uses LSUB to get subscribed mailboxes: * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE AUTH=PLAIN] Dovecot ready. . login user password . namespace * NAMESPACE (("INBOX." ".")) NIL (("public." ".")) . OK Namespace completed. . subscribe public.Admin . OK Subscribe completed. . LSUB "" "%" * LSUB () "." "INBOX" . OK Lsub completed. LSUB does not return "public" as namespace :-( Is this a bug in dovecot, a bug in Claws mail, or a misconfiguration of my dovecot server? I can provide more info if needed. Cheers, -- Julien Danjou // ᐰ <julien(a)danjou.info> http://julien.danjou.info // 9A0D 5FD9 EB42 22F6 8974 C95C A462 B51E C2FE E5CD // There is nothing under this line.

[Dovecot] Disconnected: Too many invalid IMAP commands
by Gabriele 02 Oct '09

02 Oct '09

Greetings, I'm having big issues here, hope you can help me… Ubuntu Server 8.04, postfix 2.5.1, dovecot 1.0.10, postfixadmin (MySQL+ virtual users)… I am trying to move e-mails from an old IMAP account to my new dovecot IMAP server accounts. The old server is EIMS (Eudora Internet Mail Server, so a sort of mbox format)… I move messages by drag 'n' dropping in Mozilla Thunderbird. No problems with messages under 4MB size (there are huge messages, up to 25MB), but as soon as I try to move messages from 4MB and up, the connection hangs, nothing happens, the application becomes barely responsive, I have quit and re-open it to make it behave properly. In the logs, I read (user and IPs are fake, here): Sep 18 07:52:06 in dovecot: imap-login: Login: user=<user@my-domain>, method=PLAIN, rip=123.123.123.123, lip=123.123.123.123 Sep 18 07:52:06 in dovecot: IMAP(user@my-domain): Disconnected: Too many invalid IMAP commands. Could it be a client (Thunderbird) issue? I have tried with Apple Mail 4.1, same problem, same logs. Could it be a quota limit (googling around, I read that sometimes the error may be triggered by dovecot when exceeding the quota limit) Accout usage is actually at 1%… Could drag 'n' drop be the wrong way to have things done? I have also downloaded the huge e-mails from EIMS to Thunderbird Local Folders, the problem arises when I try to upload, so the culprit seems to be the new "system". I really need help at this point… any hints? Thanks in advance for any help you will offer. Gabriele

[Dovecot] Password and special caracter
by Gilles Albusac 02 Oct '09

02 Oct '09

Problem : I have a problem with special character in the password. Character like ! * é are deleted My configuration : - a smtp server with Postfix 2.6 and Dovcot 1.1.11. - a windows 2003 server with active directory for accounts and boxes I use SMTP / SASL on my postfix 2.6 to authenticate my remote laptop users (allow legitimate users to relay mail). To do that, I use SASL Dovecot fonctionnality and ldap request to verify login/password who are declared on a server in Windows 2003 (Active Directory). It works fine with simple password but not with complex password. I have a problem with special character in the password. Character like ! * é are deleted before comparaison. Any idea ? Regards
