[Dovecot] Try with Dictionary proxy server, but... Bug or not ?

Hello again :), I try to use dictionary proxy server to replace my precedent configuration (direct use of dict in plugin quota). Before, i have this configuration in my dovecot.conf : ## Dictionary server settings dict { } ## Plugin settings plugin { # quota = 10 Mo quota = dict:storage=10240 mysql:/etc/dovecot/dict-quota.conf } And after, to use proxy, I have this configuration in my dovecot.conf : ## Dictionary server settings dict { quota = mysql:/etc/dovecot/dict-quota.conf } ## Plugin settings plugin { # quota = 10 Mo quota = dict:storage=10240 proxy::quota } My dict-quota.conf doesn't change : connect = host=localhost dbname=dovecot user=dovecot table = quota select_field = current where_field = path username_field = username My dovecot.info file : dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Effective uid=1019, gid=1019 dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Loading modules from directory: /usr/lib/dovecot/modules/imap dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Module loaded: /usr/lib/dovecot/modules/imap/lib01_quota_plugin.so dovecot: 2006-07-23 15:07:01 Info: IMAP(test): Module loaded: /usr/lib/dovecot/modules/imap/lib02_imap_quota_plugin.so dovecot: 2006-07-23 15:07:01 Info: IMAP(test): maildir: data=/home/test/Mail dovecot: 2006-07-23 15:07:01 Info: IMAP(test): maildir: root=/home/test/Mail, index=/home/test/Mail, control=, inbox= dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: uri = proxy::quota dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: byte limit = 10485760 dovecot: 2006-07-23 15:07:01 Info: IMAP(test): dict quota: count limit = 0 dovecot: 2006-07-23 15:07:01 Info: imap-login: Login: user=<test>, method=plain, rip=82.228.176.60, lip=192.168.1.60 When i use the proxy configuration, i have this error : dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:51 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:51 Error: IMAP(test): dict_quota: Couldn't update quota dovecot: 2006-07-23 15:07:52 Error: dict: sql dict: commit failed: Not connected to database dovecot: 2006-07-23 15:07:52 Error: IMAP(test): dict_quota: Couldn't update quota And in MySQL log : 060723 15:07:01 460 Connect Accès refusé pour l'utilisateur: 'dovecot'@'@localhost' (mot de passe: NON) 060723 15:07:45 461 Connect Accès refusé pour l'utilisateur: 'dovecot'@'@localhost' (mot de passe: NON) It try to connect with 'dovecot'@'@localhost'...

[Dovecot] POP does not seem to be working
by Gerard 23 Jul '06

23 Jul '06

OK, I am brand new to this so please bear with me. I have an FreeBSD 6.1 STABLE system. Postfix is installed with qpopper. The mailboxes are standard mbox format. I just installed Dovecot. At some point I want to update to a mdir format, etc., but quite frankly I do not know how to go about that. In any case, I shut down qpopper and started Dovecot. I modified the Dovecot.conf file SSL settings (turned them off) since I do not have the files it needs built yet. Anyway, when using a mail client on another PC on my network, although it makes a connection, no mail is ever downloaded. Ther is mail in the folders however. Obviously I am doing something really wrong, but I am not sure what. I would sure appreciate any assistance available. The only information I have is in the 'log' file which shows the a pop3-login, the user name, method=PLAIN, and two numeric addresses. Thanks! -- Gerard Seibert gerard(a)seibercom.net

[Dovecot] help with authentication - cpanel
by allan hardy 22 Jul '06

22 Jul '06

I am trying to install dovecot as a second pop3 service in my RH9 system. It is a Cpanel based system using Courier for primary IP By primary I mean all the other domains use courier on xxx.xxx.xxx.21 port 110 I have a domain with special pop3 needs that is dedicated to xxx.xxx.xxx.22 port 110 The two mail systems are installed, I can tell via telenet that dovecot is listening and responding on the desired IP and port Cpanel is the tool being used by all domains to create mail accounts and hence setting the 'policy' for the mailboxes, userdb and passdb information. I am trying to make dovecot use those files and can't get past authentication. What I guess I don't know is the encryption type being used by Cpanel Any help appreciated.!!!! What Cpanel appears to do for authentication is use a passwd and shadow file for each domain, placed as follows: /home/accountname/etc/domainname/passwd holds the list of mail accounts names /home/accountname/etc/domain/shadow holds the passwords This is the message log from a telnet session on local machine: dovecot: Jul 22 13:45:27 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=xxx.xxx.179.22 rip=xxx.xxx.179.22 resp=AGFsbGFuAHRlc3Q= dovecot: Jul 22 13:45:27 Info: auth(default): shadow(allan,xxx.xxx.179.22): password mismatch dovecot: Jul 22 13:45:29 Info: auth(default): client out: FAIL 1 user=allan dovecot: Jul 22 13:45:36 Info: pop3-login: Aborted login: user=<allan>, method=PLAIN, rip=xxx.xxx.179.22, lip=xxx.xxx.179.22, secured ~ This was in the shadow file: ---Shadow file entry allan:$1$V0lG6T6P$eNQoX3J3N5RJNxT5yH8gz1::::::: These are my relevant (At least I think they are relevant) dovecot.conf settings: disable_plaintext_auth = no ssl_disable = yes auth default { mechanisms = plain login anonymous passdb shadow { /home/xxxxxx/etc/xxxxx.com/shadow } userdb passwd-file { # Path for passwd-file args = /home/xxxxxxx/etc/xxxxx.com/passwd } --PAM is commented out As a side note, I tried to see if I could tell from the courier setup how it was authenticating. The courier/etc/pop3d file was set POP3AUTH="" And there was a note "To advertise the SASL capability, per RFC 2449, uncomment the POP3AUTH variable" So it this may indicate sasl is being used, what ever that means

[Dovecot] cmusieve plugin
by Stuart Sears 21 Jul '06

21 Jul '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys I have been doing a lot of searching, but maybe I am being dim (not unheard of!). I have dovecot-1.0rc2 built and running on Fedora Core 5. The wiki page (dated yesterday) states that I need the cmusieve plugin to use sieve scripts with the dovecot lda. Is this a new development? They seem to work quite happily on my soon-to-be retired 1.0-beta7 debian box without an extra plugin. secondly, if it is now necessary, where do I get this plugin from? (this may be the dim part) I have a cvs checkout of the dovecot sources, but I see nothing obviously connected to cmusieve anywhere in the source tree If this is in a different module, then can someone let me know the name of it, so that I can check it out of CVS as well?

[Dovecot] Migrating to dovecot
by Johann Spies 21 Jul '06

21 Jul '06

I do not have much experience in setting up imap servers - only that I have tried several and experienced the same problem with all of them. I suppose that is because I do not really know the in's and out's of an imap server. What I want to do is to setup an IMAP server on my PC with full access to all the emails already there in a maildir structure. I have the following setup: fetchmail -> procmail -> maildir exim for outgoing mail. When I install an imap server, I loose access to my present emails in ~/Mail and most imap-servers (dovecot included) seems to create a new structure within ~/Mail. ~/Maildir is a symlink to ~/Mail. Now my questions: 1. How do I set up dovecot to serve the present maildir to the user? 2. Related to 1: How do I migrate my emails to the new imap-maildir structure without losing any? 3. How would my present procmail-setup change? At the moment I have entries like the following: MAILDIR=$HOME/Mail # you'd better make sure it exists DEFAULT=$MAILDIR/Ander/new # completely optional :0: * X-Spam-Flag: YES saspam/new :0: * ^List-Id: <users.spamassassin.apache.org> spamassassin/new ...

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues, -- Philipe Gaspar Universidade Salvador Fone:+55 (71) 3273-8592

[Dovecot] Patch suggestion
by Renaud Allard 20 Jul '06

20 Jul '06

Hi, Would it be possible to make a change in the configure file to search for gssapi.h in <kerberosV/gssapi.h> if it fails to find it in <gssapi/gssapi.h>? That would allow to compile dovecot with gssapi easily on OpenBSD without patching it.

[Dovecot] making Dovecot match Courier POP3 UID's
by Jeff Tucker 20 Jul '06

20 Jul '06

Hi, guys. I've read the information in the Wiki about making dovecot's UID's match Courier's UID's in the POP3 server, so that a UIDL command on either server will return the same UID's for the same group of messages. However, what I've read doesn't match what I'm seeing in Courier. Courier appears to keep the UID numbers for messages that it uses for the POP3 server separate from the UID numbers for the IMAP server. Courier has a file: courierpop3dsizelist which has a line for every message, like: 1129610881.6075832619.blade4:2,S 2361 1478:1065670602 1129727025.1168007000.blade1:2,S 14718 1479:1065670602 1130005953.3295720403.blade5:2,S 1554 1481:1065670602 1130108068.0849623942.blade5:2,S 8246 1482:1065670602 The first column is the maildir filename, the last column is the UID that the POP3 server uses and the UID validity. Both are used to create the UID number returned by UIDL. The IMAP server uses a completely different UID number that's stored in courierimapuiddb. So, it seems to me that dovecot can't ever match Courier's UID numbers for the POP3 server unless it reads and interprets this courierpop3dsizelist file. My Courier-IMAP installation is Courier-IMAP 4.0.6. Any ideas? This is a real hassle because it means I can't switch the POP3 server from Courier to Dovecot or, if I do, lots of my users will download every message again which is just unacceptable. Thanks Jeff

[Dovecot] proxy performance
by Vincent Fox 19 Jul '06

19 Jul '06

Can anyone speak to experience using Dovecot proxy to frontend for multiple back-end servers in a "large" environment? We have 50,000+ mailboxes spread across 10 POP/IMAP servers. We'd like to be able to put in a front-end setup on our load-balancer of 4 dual-CPU Sun systems. I am a bit concerned about performance issues although from what I have read the proxy can be set not to fork, which improves performance a lot. Still concerned about whether SSL loading will be an issue. We'd like to use LDAP to look up the reference to which mail-store a user is on. I see that the Wiki refers to SQL. The mailing list indicates passwd-file also works. Not clear about LDAP.

[Dovecot] /var/spool/mail directory size and subdirectories
by David Lee 19 Jul '06

19 Jul '06

(Complete newbie to dovecot. I hope what follows isn't something I've missed in some FAQ somewhere...) On a traditional UNIX filesystem with UW-IMAP several years ago, we encountered major performance problems when "/var/spool/mail/" got big (we would currently be ~20,000 entries). This was due to the inefficiency of the UNIX filesystem when creating and deleting the lockfiles (etc.) in a directory of that size. We worked around that (all those years ago) with a local source-code mod to UW-IMAP ("c-client") to use subdirectories "/var/spool/mail/00/" to "/var/spool/mail/99/" based on a trivially simply "uid mod 100" algorithm. (Our uids are random; our usernames are not.) Thus we had 100 subdirs each of about 200 entires. Efficiency and performance vastly improved, and we've been running like that ever since. Now we are considering migrating to dovecot... Does dovecot do file creation/deletion in this (or similar shared) directory? (And so would it be liable to the same inefficiency problems?) Is there some means in the "dovecot.conf" file to specify an INBOX pattern as "/var/spool/mail/%ZZZ%/%u" where "%ZZZ%" could be algorithmically specified as (say) "user-uid mod 100"? -- : David Lee I.T.

[Dovecot] data corruption in delivery agent when forwarding
by Joshua Goodall 19 Jul '06

19 Jul '06

Hi Timo I've been seeing data corruption in the lda when forwarding mail. I think it's due to confused file pointers. (this is all maildirs on nfs) Anyway the following patch fixes it, and also looks a bit more like the old dovecot-lda module, by getting the Return-Path header before getting the input stream: Index: mail-send.c =================================================================== RCS file: /home/cvs/dovecot/src/deliver/mail-send.c,v retrieving revision 1.1.2.1 diff -u -r1.1.2.1 mail-send.c --- mail-send.c 11 Jun 2006 11:10:55 -0000 1.1.2.1 +++ mail-send.c 19 Jul 2006 09:28:18 -0000 @@ -116,16 +116,17 @@ struct smtp_client *smtp_client; FILE *f; const unsigned char *data; + const char *return_path; size_t size; int ret; + return_path = mail_get_first_header(mail, "Return-Path"); + input = mail_get_stream(mail, NULL, NULL); if (input == NULL) return -1; - smtp_client = smtp_client_open(forwardto, - mail_get_first_header(mail, "Return-Path"), - &f); + smtp_client = smtp_client_open(forwardto, return_path, &f); input = i_stream_create_header_filter(input, HEADER_FILTER_EXCLUDE | HEADER_FILTER_NO_CR, hide_headers, best regards as ever /k -- Josh "Koshua" Goodall "as modern as tomorrow afternoon" joshua(a)roughtrade.net - FW109

[Dovecot] strange dropping of Word.doc-attachements - sendmail dovecot RHEL4
by Götz Reinicke 19 Jul '06

19 Jul '06

Hi, we have a strange problem: two of our users informed me, that they aren't able to send word-.doc-files anymore while othe attachements work fine. The e-mail gets deliverd, but the attachement is dropped. This happens using the latest thunderbird 1.5.x and mac os x. The e-mail is also not saved in the send-drawer. If the users send the same e-mail to the same recepient using an other mailclient, there is no problem. Other users (like me) using the same systemsettings and software versions don't have the problem. The server is RHEL 4 (2.6.9-kernel), sendmail 8.13.1 and dovecot 0.99. We use Mailscanner and spamassassin too, but as only the two users do have the problem I'm looking for some help to track this problem down. Any ideas?? Thanks and best regards Götz Reinicke -- Götz Reinicke IT Koordinator Tel. +49 7141 969-420 Fax +49 7141 969 55-420 goetz.reinicke(a)filmakademie.de Filmakademie Baden-Württemberg Mathildenstr. 20 71638 Ludwigsburg www.filmakademie.de

I'm using dovecot on our new mail server and it is pretty good. But I have a problem regarding quota limits, I am using quota plugin on imap, pop3 and LDA, the deliver agent blocks new messages for delivery, like hard quota. I'd like to use LDA with quota plugin regarding soft quota. Thanks for any clues,

[Dovecot] Masking INBOX.INBOX
by Ben Schumacher 18 Jul '06

18 Jul '06

I am using dovecot and trying to make it compatible with my a BincIMAP installation. BincIMAP uses a scheme similar to Courier-IMAP, so I set up this default_mail_env: default_mail_env = maildir:~/Maildir And this namespace: namespace private { separator = . prefix = INBOX. inbox = yes } Which mostly works as expected, but I now see an "INBOX" subfolder of "INBOX" in LIST: * OK Dovecot ready. 1 login ben ******** 1 OK Logged in. 2 list "" "*" * LIST (\HasChildren) "." "INBOX" * LIST (\HasNoChildren) "." "INBOX.INBOX" * LIST (\HasNoChildren) "." "INBOX.Drafts" * LIST (\HasChildren) "." "INBOX.Jabber" * LIST (\HasChildren) "." "INBOX.Keepers" * LIST (\HasChildren) "." "INBOX.Ruby" * LIST (\HasNoChildren) "." "INBOX.Trash" * LIST (\HasNoChildren) "." "INBOX.Sent" * LIST (\HasNoChildren) "." "INBOX.Spam" * LIST (\HasNoChildren) "." "INBOX.postmaster" * LIST (\HasNoChildren) "." "INBOX.qmail" * LIST (\HasNoChildren) "." "INBOX.Jabber.XMPPWG" * LIST (\HasNoChildren) "."

"INBOX.Keepers.2005" * LIST (\HasNoChildren) "." "INBOX.Ruby.ruby-talk" 2 OK List completed. Is there anyway to mask this from displaying? I've toyed with various configurations to try to hide it, but nothing seems to work. What's annoying is this situation: 3 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Drafts" 3 OK Lsub completed. 4 SUBSCRIBE "INBOX" 4 OK Subscribe completed. 5 LSUB "" "*" * LSUB () "." "INBOX.Spam" * LSUB () "." "INBOX.Trash" * LSUB () "." "INBOX.Sent" * LSUB () "." "INBOX.Drafts" * LSUB () "." "INBOX.INBOX" 5 OK Lsub completed. Note that in my first LSUB the main "INBOX" isn't subscribed to. I then "SUBSCRIBE" in 4 to "INBOX" and dovecot translates that to subscribing to "INBOX.INBOX". Not a huge deal, but it does cause Thunderbird to act weirdly (although Thunderbird allows me to UNSUBSCRIBE to "INBOX" and still get new mail), but I'm not sure what the effect will be on other clients. Any ideas? Thanks, Ben

Hi ya'll I'm using dovecot 0.99.11 and I have a doubt about some folders. The Inbox folder is greyed out on most of my clients, and I just cannot move any message (on other folders) into inbox. I'd like to know if I can do that. Besides that, when I select the Drafts folder I get the "Mailbox isn't selectable" warning, and cannot save any drafts there so, how could I change that?

[Dovecot] Getting maildir++ quotas working
by Bill Boebel 18 Jul '06

18 Jul '06

Can somebody post details for how to get maildir++ quotas working in the latest CVS? I have tried but can't get the CAPABILITY string to show "QUOTA"; and the GETQUOTAROOT command is recognized, but returns nothing... 2 GETQUOTAROOT INBOX * QUOTAROOT "INBOX" "" * QUOTA "" () 2 OK Getquotaroot completed. These are the settings I have... am I missing something? protocol imap { mail_plugins = imap_quota quota mail_plugin_dir = /usr/lib/dovecot/imap } plugin { quota = maildir imap_quota = maildir } Here are some more details: Dovecot is creating the maildirsize file in my maidir, and it seems to show correct storage used calculations, but the first line which should contain my storage limits is blank. So I suspect that I am not returning a valid quota value from the user database. I am returning what my old Courier-IMAP wants to see "1073741824S,4000C"... if the format for Dovecot is different, what should the format be? So there are two problems that I am trying to resolve, but I'm not sure how to go about fixing it. Any help would be greatly appreciated: (1) Dovecot isn't announcing QUOTA support in the capability string. (2) Dovecot isn't getting a valid quota limit, which I assume is breaking the GETQUOTAROOT command. Thanks, Bill

[Dovecot] Empty messages in 1.0RC2
by Renaud Allard 18 Jul '06

18 Jul '06

Hello, I am running 1.0RC2 (upgrade from a beta, so I haven't tested RC1 unfortunately). I sometimes get empty messages in my inbox folder. Mails are stored using Maildir. Here is an output of a ls -la ~/Maildir/cur -rw------- 1 n users 0 Jul 18 09:31 _CFC+Y5IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:28 _bEG+A2IvEB.gandalf.llorien.org:2, -rw------- 1 n users 0 Jul 18 09:54 _ezF+eOJvEB.gandalf.llorien.org:2, -rw------- 1 n users 2246 Jul 18 08:10 msg.f23:2,RSa There is one real message (the last one). All messages seems to have strange file names names, even the real one. Messages delivered by the MTA generally have a name like 1152736772.H956194P17632.mail.llorien.org:2,RS There is nothing in the SMTP server logs that could suggest these empty mails are delivered with SMTP and only dovecot version has changed. So I guess this is dovecot related. My IMAP client is thunderbird on Linux, but I have also seen the problem with sylpheed on OpenBSD. Any help or hint appreciated.

[Dovecot] Postfix Virtual Users and Directory Permissions
by Michael Starks 18 Jul '06

18 Jul '06

I have followed the instruction here: http://www.postfix.org/VIRTUAL_README.html#virtual_mailbox There are five virtual domains configured and each directory containing each domain is owned by one UID/UID with permissions of 700. I can send mail to each domain and it is stored in the appropriate Maildir under the correct directory. The system is OpenBSD 3.8 STABLE. So far, so good. Now comes Dovecot. What I would like to do is to have one set of credentials for 4 of the domains, and another for the remaining. I would also like to *not* use a database backend for authentication at this time and would prefer to stick with standard UNIX /etc/passwd and /etc/shadow. Considering the directories are all owned by one user, does Dovecot need to be configured to use the same user as auth_userdb = static? That would make sense. What I'm not clear on is how Dovecot would know which domains are associated with which user, and does the user need permissions to those directories or is that handled by impersonation? Thanks in advance.

Hello, I just installed dovecot and postfix on a Fedora Core VPS. The VPS will not allow me to ssh directly as user "root" i.e.: I must first login as a non-root user and then "su" into root. My question is: is there a way to read my root mail through Dovecot ? How should I setup the Thunderbird account ? Thank you... SJ

[Dovecot] pop3 auth problem solved!
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow techies, OK... This is going to go down as one of those "D'Oh!" moments in the world of computers. Boy, do I feel dumb... In short: I found the problem. One miserable little line in 'dovecot.conf' called 'auth_default_realm =.' I had this set to 'bluefeathertech.com,' thinking it was necessary to do so. I was wrong, at least for my environment, and the stupid clues were right in front of me in the logfile all the time! For the benefit of others who may run into this: Setting a domain name in this entry causes that domain name to be automatically appended to usernames when they log in. No wonder nothing ever matched in /etc/passwd! My deepest thanks to Frank Cusack for giving me the idea. Something he said in his post, in response to my initial one, got me thinking about things getting appended to the user name, and the rest is history. pop3 and pop3s both work just fine now, thanks. ;-) Keep the peace(es). -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

[Dovecot] pop3 authentication problems: Still got 'em...
by Bruce Lane 16 Jul '06

16 Jul '06

Fellow users, This is just a heads-up to let the list know that I'm still unable to get ANY sort of pop3 or pop3s authentication to work with Dovecot. Just as a sanity check, I set up an entirely separate system, running FreeBSD 6.1 production, postfix 2.3, and Dovecot 1.0rc2, as a testbed. I got the exact same problem that I had with the NetBSD 3.0 production server, specifically that Dovecot refuses to authenticate a user with either basic pop3 or pop3s. The way I see it, I may as well try to get basic pop3 working first. If it doesn't, pop3s will never work. This first quote is taken from the mail client (Pegasus) trying to establish a regular, unencrypted pop3 session. -=-=-=-=-=-=- [*] Connection established to 192.168.42.80 >> 0058 +OK AVG POP3 Proxy Server 7.1.368/7.1.394 [268.10.1/389] << 0013 USER kyrrin >> 0005 +OK << 0016 PASS XXXXXXXXX >> 0029 -ERR Authentication failed. -=-=-=-=-=-=-=- As you can see, the user ID of 'kyrrin' is getting passed as just that, and Dovecot at least seems to recognize it.

[Dovecot] auth with kerberos
by Renaud Allard 16 Jul '06

16 Jul '06

Hello, I am running dovecot 1.0RC2 and I'd like to know if there is a way to make dovecot provide PLAIN, LOGIN, CRAM-MD5, NTLM authentications from a kerberos database. GSSAPI works great, but I currently have to have two password databases, one for GSSAPI and one for all the others. What I'd like is to have only one password database (namely kerberos). I know that cyrus-sasl (which most of you don't like I think ;)) can provide such authentications, but I haven't found the way to configure dovecot to do the same. Any input welcome.

Re: [Dovecot] Deliever in RC2 incorretly outputs "saved mail to INBOX"
by Alex Pimperton 14 Jul '06

Hi All, I've recently upgraded to RC2 (debian package) and now I get the following message in syslog all the time: Jul 14 15:51:04 server01 deliver(alex): saved mail to INBOX This seems to happen for every mail, despite some being filtered into different folders. It goes like this: Mail arrives from Ubuntu mailing list: Jul 14 15:53:49 server01 postfix/qmgr[19023]: D51A95C023: from=<ubuntu-users-bounces(a)lists.ubuntu.com>, size=4319, nrcpt=1 (queue active) I get this message: Jul 14 15:53:51 server01 deliver(alex): saved mail to INBOX Postfix sends to deliver: Jul 14 15:53:51 server01 postfix/local[29843]: D51A95C023: to=<alex(a)placet.co.uk>, relay=local, delay=29, status=sent (delivered to command: /usr/lib/dovecot/deliver) ...and a few seconds later it shows up in my Ubuntu-Users folder, exactly where my sieve rule sends it. Is this a bug? Alex -- This message has been scanned for viruses and dangerous content by the MailScanner at Placet.co.uk, and is believed to be clean.

[Dovecot] Backing up mail
by Davide Bolcioni 14 Jul '06

14 Jul '06

Greetings, in backing up mail stored according to default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u is it safe *not* to backup the .imap subdirectory ? I am currently using dovecot-0.99.13-3.FC3. When restoring, I guess the safe option would be to zap the contents of .imap so that it gets rebuilt, correct ? Thank you for your consideration, Davide Bolcioni -- Paranoia is a survival asset.

[Dovecot] TLS Issues - Plain Text login?
by Timothy White 14 Jul '06

14 Jul '06

I'm trying to setup IMAP, so that it works via secure connections. I have it working fine over SSL, now I wish to get TLS to work. I have set imap and imaps to both listen on *, and have disable_plaintext_auth = yes, which according to the docs, Disable LOGIN command and all other plaintext authentications unless SSL/TLS is used (LOGINDISABLED capability). So the problem is now, that TLS doesn't work. Trying it with thunderbird, I get a message about login being disabled, and to check my settings and such. The port is correct (imap, not imaps), and I have it to always use TLS. I see the following in my logs Jul 14 16:35:46 mafeking dovecot: imap-login: Aborted login: rip=58.7.136.163, lip=203.30.47.34, TLS Any ideas? To me it appears to be using TLS, so why doesn't thunderbird work? Is it the LOGINDISABLED capa keyword? Is it dovecot telling Thunderbird the wrong capa when using TLS? It all works fine with SSL, and the port (in thunderbird) set to the imaps port. The logs show lines like below when using SSL. Jul 14 16:36:32 mafeking dovecot: imap-login: Login: user=<joeblogs>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured Any ideas? Or should I just force SSL?

[Dovecot] dovecot 1.00 RC2 bugs
by Alexander Zagrebin 14 Jul '06

14 Jul '06

imho, dovecot 1.00 RC2 has two bugs at the maildir quota implementation 1. Incorrect calculation of used storage and count of messages When calculating, dovecot counts "." and ".." directory entries. So, if there are no subdirs and messages in maildir, maildirsize still shows 4 messages and some used storage. My workaround is --- src/plugins/quota/quota-maildir.c.orig Sun Jun 11 21:36:24 2006 +++ src/plugins/quota/quota-maildir.c Thu Jul 13 11:33:58 2006 ======================================================== @@ -82,6 +82,8 @@ len = str_len(path); while ((dp = readdir(dirp)) != NULL) { + if (!strcmp(dp->d_name, ".")) continue; + if (!strcmp(dp->d_name, "..")) continue; p = strstr(dp->d_name, ",S="); num = (uoff_t)-1; if (p != NULL) { ======================================================== This patch skips special directory entries. 2. Under some condition maildirsize contains invalid data Consider a such situation 1. User begins pop3 session 2. dovecot calls this sequence of procedures maildir_quota_transaction_begin -> maildirquota_refresh -> maildirsize_read While reading maildirsize's data, may be situation when mailbox size must be recalculated (maildirsize greater 5120, quotas was changed...). In this case dovecot closes maildirsize's file descriptor (root->fd) and assigns it "-1". After that code calls maildirsize_recalculate -> maildirsize_write So maildirsize is rewritten and contains valid data. BUT file descriptor (root->fd) still contains "-1" 3. User retrieves and deletes some messages, then quits. So maildirsize must be updated. 4. Code calls maildir_quota_transaction_commit, but root->fd equals "-1", so maildirsize_update doesn't calls and maildirsize contains incorrect (obsolete) data My workaround is ======================================================== --- src/plugins/quota/quota-maildir.c.orig Sun Jun 11 21:36:24 2006 +++ src/plugins/quota/quota-maildir.c Thu Jul 13 11:33:58 2006 @@ -246,11 +248,12 @@ return -1; } - if (file_dotlock_replace(&dotlock, 0) < 0) { + if (file_dotlock_replace(&dotlock, DOTLOCK_REPLACE_FLAG_DONT_CLOSE_FD) < 0) { mail_storage_set_critical(storage, "file_dotlock_replace(%s) failed: %m", path); return -1; } + root->fd = fd; return 0; } ======================================================== This patch preserves fd after writing recalculated maildirsize file, and when maildir_quota_transaction_commit is called, root->fd contains valid file descriptor. -- Alexander Zagrebin

[Dovecot] pop3s Authentication Issues, Continued
by Bruce Lane 14 Jul '06

14 Jul '06

Fellow Dovecot'ers. I tried something tonight that I should have done a while back: Turned on verbose logging in the authentication section. I'm still unable to get the mail client I'm experimenting with (Pegasus) to complete a pop3s connection, in that I still get an indication of a failed password. However, at least I'm a little closer to understanding the failure itself. Please note what came up in /var/log/maillog. Jul 13 22:41:25 featherweb dovecot: auth(default): client in: AUTH 1 PLAIN service=POP3 secured lip=192.168.42.130 rip=192.168.42.40 resp=AGt5cnJpbgBocDIxZHZlbTc= Jul 13 22:41:25 featherweb dovecot: auth(default): cache(kyrrin(a)bluefeathertech.com,192.168.42.40): User unknown Jul 13 22:41:26 featherweb dovecot: auth(default): client out: FAIL 1 user=kyrrin(a)bluefeathertech.com More specifically: Take a good hard look at the end of the second line.

Re: [Dovecot] Error: imap-login: Can't connect to auth server at default: Resource temporarily unavailable
by Matt Roman 13 Jul '06

13 Jul '06

It appears the problem is in this function: int net_connect_unix(const char *path) { struct sockaddr_un sa; int fd, ret; memset(&sa, 0, sizeof(sa)); sa.sun_family = AF_UNIX; if (strocpy(sa.sun_path, path, sizeof(sa.sun_path)) < 0) { /* too long path */ errno = EINVAL; return -1; } /* create the socket */ fd = socket(PF_UNIX, SOCK_STREAM, 0); if (fd == -1) { i_error("socket(%s) failed: %m", path); return -1; } net_set_nonblock(fd, TRUE); /* connect */ ret = connect(fd, (void *)&sa, sizeof(sa)); if (ret < 0 && errno != EINPROGRESS) { close_keep_errno(fd); return -1; } return fd; } This function is returning -1 and the server is crashing - Most likely because of a socket error. The error message from the socket is "Resource temporarily unavailable" If anybody knows why that would happen, I might be able figure out a solution. Thanks!

[Dovecot] maildir++ quota bug...
by Joseph W. Breu 13 Jul '06

13 Jul '06

Running RC2 with maildrop and MDA: dovecot writes a positive quota count, then the negative quota count on messages delivered with maildrop. For example, message #1 arrives via maildrop: 4488236 1 message is deleted via dovecot: 4488236 1 -4488236 -1 This does not happen when the user accesses the message, only when it is deleted. The user never gets credit for deleting the file and their quota continues to grow. I did not notice this behaviour until now, but I just tested with rc1 and it is present there as well.

[Dovecot] proxy load-testing
by Vincent Fox 13 Jul '06

13 Jul '06

I found the proxy performance page in the Wiki. It's interesting to see such good performance for the proxy! However, I was trying to duplicate the tests and am not clear how. Anyone know what a typical test setup would look like? I need to document/test that I can setup a proxy able to handle 100-200 sessions per second which the folks around here are skeptical of. I emailed Tomi directly but got a vacation reply. I tried a quick test of my own with rabid and results seem questionable. Probably I am not using the right options on the command-line. I used a single client to generate the load and while I specified 20,000 per minute when I checked the maillog on my IMAP server it was authentication more like 300 per minute. I get a number of "Re-auth failure" messages even with 3720 accounts. I think this is due to the randomness being literal sometimes you hit again the same account name while a first attempt of it is still connected. Also not sure how Tomi generated those statistics, from the logs, from the rabid output? Since rabid doesn't do POP-mark numbers or anything I guess you just ramp up the load until the proxy slows down and call that your performance number?

[Dovecot] Squirrelmail Change Dovecot Password Plugin
by Cecil S. Nutakor 13 Jul '06

13 Jul '06

Hi Let me introduce myself, My name is Cecil, and i am a system architect by proferssion working currently on contracts with serveral companies in Ghana and Nigeria. I recently built a Corporate Mail Server for a Company using Postfix, Dovecot and Squirrelmail, running on Ubuntu. Thanks to the Dovecot community everything is working well. After a moment i noticed that i could make the users change their own passwords using squirrelmail, but unfortunatly for me after googling around the Internet and also visiting squirrelmail plugin page i could not find a change Dovecot password plugin for squirrelmail. I want to throw this challenge to the Dovecot community to start a project on developing a change Dovecot password plugin for squirrelmail if none exis t as at now. I am ready to voluntee towards the development of the plugin. I will like to know from others especially the list administrators if the project can take off on the mailling list with any problems. Thank You. Office Of The SYSTEMS ARCHITECT DISCOVERYTEL GH

Hi Alexander, > > Thanks for the quick reply; rearranging the certs didn't seem to do > much for the setup; I guess I'm getting one thing wrong, which was the > cause for my followup. How can I make dovecot only rely on cert and no > furhter authentication for giving access to the user, when making > dovecot lift the user ID from the client cert? Hmm, i don't think that's the reason for the "invalid certificate" error. Another question: are the clientcertificates and the servercertificate signed by the same CA? In case you want the ssl-verify error in the logfiles: in src/logincommon/ssl-proxy-openssl.c, line 607 change: i_info("Invalid certificate: %s", buf); to: i_info("Invalid certificate: %s: %s, X509_verify_cert_error_string(ctx->error) ,buf); should help, (tested on beta8) (don't forget to recompile, install, restart ;-)) success! -- groeten, HenkJan Wolthuis

Re: [Dovecot] Quota over 2GB supported?

Yes, we are enforcing a 5GB per user quota using Dovecot's maildir++ quota support. This works with both 32-bit kernels and 64-bit. I know courier took some patching to make work with 32-bit kernels, but Dovecot supports it out of the box. The only caveat is the quota is only enforceable within one namespace, so make sure your Inbox and folders all use the same namespace. Bill
