[Dovecot] troubleshooting new dovecot installation
by Ray 08 May '07

08 May '07

Hello, I'm setting up a new mail server using freebsd 6.2, postfix, dovecot with SASL and, eventually, squirrelmail. I've gone through http://wiki.dovecot.org/TestPop3Installation the program is running, plain works over telnet from local host or from a remote machine. I can do stat and retr commands. however, when I try to use the login method (that is what the command 1 login username password part is, isn't it?) all I get is: -ERR Unknown command. even with auth_verbose = yes auth_debug = yes, logs give no information. May 7 20:41:53 server dovecot: pop3-login: Disconnected: rip=1.2.3.4, lip=1.2.3.4 (IP's substituted) almost all of the users will be using outlook/outlook express so I'm only enabling plain and login methods. thanks Ray dovecot -n gives protocols: imap pop3 ssl_disable: yes disable_plaintext_auth: no login_dir: /var/run/dovecot/login login_executable(default): /usr/local/libexec/dovecot/imap-login login_executable(imap): /usr/local/libexec/dovecot/imap-login login_executable(pop3): /usr/local/libexec/dovecot/pop3-login verbose_proctitle: yes first_valid_gid: 0 mail_extra_groups: mail mail_location: maildir:/usr/local/mail/%d/%n mail_executable(default): /usr/local/libexec/dovecot/imap mail_executable(imap): /usr/local/libexec/dovecot/imap mail_executable(pop3): /usr/local/libexec/dovecot/pop3 mail_plugin_dir(default): /usr/local/lib/dovecot/imap mail_plugin_dir(imap): /usr/local/lib/dovecot/imap mail_plugin_dir(pop3): /usr/local/lib/dovecot/pop3 imap_client_workarounds(default): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(imap): delay-newmail outlook-idle netscape-eoh tb-extra-mailbox-sep imap_client_workarounds(pop3): outlook-idle pop3_uidl_format(default): pop3_uidl_format(imap): pop3_uidl_format(pop3): %08Xu%08Xv pop3_client_workarounds(default): pop3_client_workarounds(imap): pop3_client_workarounds(pop3): outlook-no-nuls oe-ns-eoh auth default: mechanisms: plain login passdb: driver: pam passdb: driver: sql args: /usr/local/etc/dovecot-sql.conf userdb: driver: passwd userdb: driver: prefetch args: /usr/local/etc/dovecot-sql.conf socket: type: listen client: path: /var/spool/postfix/private/auth user: postfix group: postfix master: I don't think it matters, but for the sake of formality: server# grep -v '^ *$#.*$\?$' dovecot-sql.conf driver = mysql connect = host=/tmp/mysql.sock dbname=******** user=******** password=******* password_query = SELECT md5(userpassword) AS password, home, virtual_uid AS userdb_uid, virtual_gid AS userdb_gid FROM virtual_users WHERE email = '%u' AND active = 1

Re: [Dovecot] What would you tell the CIO in an "ABCs of Email" overview?
by Kenneth Porter 08 May '07

08 May '07

Perhaps the first fundamental is that Internet email isn't handled by one kind of server. It's a suite of protocols that are served by distinct processes. At minimum, you have inbound (POP3, IMAP) and outbound (SMTP) servers. You may also have a separate authentication server (LDAP) and perhaps other pieces providing calendaring, web mail (HTTP), and central storage of client configuration (ACAP). The different protocols exist not because some programmer thought it would be cool to create a new protocol, but because they serve completely different needs. For example, POP3 was designed to support lightweight disconnected clients. IMAP provides server-based storage of mail folders. LDAP provides authentication not just for mail systems but for many other applications. (I'm sure experts for each of these protocols could provide better explanations. The RFC for each probably has a motivation section that you can quote.) An important "slide" in the presentation would show the plumbing that ties all these protocols and processes together and shows how mail moves through the system. In some cases the plumbing itself is variable. For example, spam and virus processing might occur within several servers or within a client.

[Dovecot] sieve parse error
by Matthias Kellermann 06 May '07

06 May '07

Hello everyone, I'm using Dovecot (v1.0.beta3-3ubuntu5.4 under Ubuntu) with postfix and LDA with virtual users. Everything is working fine. To filter mails I use the Dovecot Sieve feature. But I get some strange error for one simple Sieve script: ---------------------------------------------------------------------------------------------------- require "fileinto"; if header :contains ["to", "Cc", "Bcc"] ["freewrt-users(a)freewrt.org"] { fileinto "Mailinglists.FreeWRT"; stop; } elseif header :contains ["to", "Cc", "Bcc"] ["getmail(a)discworld.dnsalias.org"] { fileinto "Mailinglists.getmail"; stop; } ---------------------------------------------------------------------------------------------------- This is the error I get in mail.log: ---------------------------------------------------------------------------------------------------- May 6 15:47:08 gehirnschnecke deliver: sieve parse error for matthias(a)adminlife.net: line 8: syntax error, unexpected IF, expecting '{' ---------------------------------------------------------------------------------------------------- After studying sieve.info my sieve script should be correct. What could be wrong here? Thanks & best regards Matthias

This kind of behavior looks like a network issue. > You called it. We access the server over the Internet. How did I forget to provide that small detail? However, that's not the slowness I speak of. Perhaps a better term is long delay, like waiting on some timeout, before message loadding (in symptom 1., above). So are there parameters to tune, that will make dovecot behave nicer? I do not believe this to be connectivity outages between our clients and the server. For one, we never experienced these symptoms with UW-IMAP. I just duplicated the stall on copying to Sent folder. This is probably the more prevalent, and annoying of the two problems. facts: * There was only one active client. * The client was T'bird, v1.5.0.10, running on XP. * This particular test had a 3Mb attachment. * The mail was delivered immediately to the single, remote recipient (after a ~20 seconds of 3Mb upload). * The "Copying to Sent Folder" dialog stayed up for (no exaggeration) 15-minutes, and then completed; the message is in the Sent folder now. suspicion, from months of experiencing the behavior: * Attachments are usually involved. How does the config look? Are the mbox lock settings appropriate? I was somewhat shooting in the dark there. * Sendmail 8.13.6/8.13.6 * $sudo sendmail -bt -d0.10 < /dev/null | grep HASFLOCK OS Defines: BSD4_4_SOCKADDR HASFCHOWN HASFCHMOD HASFLOCK mbox_read_locks = flock mbox_write_locks = flock What else can I provide? netstats? tcpdumps? Are there logs/debugging appropriate to enable? Thanks for any ideas, Danno

[Dovecot] Converting Courier mailboxes to Dovecot
by Andy Shellam 05 May '07

05 May '07

Hi, I have around 100 mailboxes (maildirs) to convert from Courier IMAP (4.1.3) to Dovecot. (From a recent backup) I've tested a few mailboxes on Dovecot 1.0.0, and while the client doesn't notice any difference (at least in Thunderbird) I'm hoping to get rid of the old Courier folders and convert any useful information they may have into Dovecot. I've tried Timo's migration script (http://www.dovecot.org/tools/courier-dovecot-migrate.pl) but it fails at line 230 with a "no file/directory" error. At that line, it appears to be finding Courier's keywords folder (courierimapkeywords), and looking for a file called ":list". However in my mailboxes, there's no file by that name, only what looks like a set of standard IMAP filenames, most of which are empty files. If I can't salvage anything useful, is there any adverse effects to me deleting all the "courier*" files/folders from each mailbox and subfolders so when the client connects back when Dovecot's running, it creates it's own UIDs and keywords etc? Thanks Andy.

[Dovecot] Help with LDAP authentication - user / user+domain
by Venilton Junior 04 May '07

04 May '07

Hello Folks, I've my dovecot working well and authenticating in my ldap servers. But I'd like configure my users to authenticate in two ways. One is just submitting the username and the other one is providing user(a)domain.com . I'm moving from a cyrus-imap solution to dovecot and I've implemented it with VD domains. But nowadays I still have one domain at my servers. So to no cause to much impact to users, I'd like to provide this two ways of authentication. Here follows my dovecot-ldap.conf: hosts = localhost dn = uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot dnpass = XXXXXX auth_bind = no ldap_version = 3 base = dc=domain,dc=com deref = never scope = subtree user_attrs = mail,homeDirectory,,,,quota=quota=maildir:storage user_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) pass_attrs = mail,userPassword pass_filter = (&(objectClass=VirtualMailAccount)(mail=%u)(accountActive=TRUE)(delete=F ALSE)) default_pass_scheme = SSHA user_global_uid = 100 user_global_gid = 101 My logs: Apr 30 13:47:58 server dovecot: auth(default_with_listener): client in: AUTH 1 PLAIN service=POP3 lip=xxx.xxx.xx.xx rip=xxx.xx.xxx.xxx resp=AGpveWNlLm1hcmlhbm8AbWFrdHVi Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): pass search: base=dc=domain,dc=com scope=subtree filter=(&(objectClass=VirtualMailAccount)(mail=user.test)(accountActive= TRUE)(delete=FALSE)) fields=mail,userPassword Apr 30 13:47:58 server dovecot: auth(default_with_listener): ldap(user.test,xxx.xx.xxx.xxx): unknown user Apr 30 13:47:59 server dovecot: auth(default_with_listener): client out: FAIL 1 user=user.test Apr 30 13:48:05 server dovecot: pop3-login: Aborted login: user=<user.test>, method=PLAIN, rip=xxx.xx.xxx.xxx, lip=xxx.xxx.xx.xx If I provide user.test(a)domain.com works fine.

[Dovecot] Sieve not recognizing keywords
by Alexander Hoogerhuis 04 May '07

04 May '07

First, I've been lurking and using dovecot for a few years now and I've always liked it, great piece of software! :) I've finally decided to clean up my act here and get virutal users and get postfix (2.3), dovecot (1.0.0) and deliver to play nice, using postfixadmin. I have it 99% there, but one thing is left: When I receive mails, deliver finds my virtual home dir and then tries to compile the sieve script (converted from procmail with the script mentioned in the wiki), and then always bums out on this: sieve parse error: line 3: Unsupported features in require line and line 3 looks like this: require ["fileinto","regex","envelope","vacation"]; which should be fine? Then I googled around and found this thread from january: http://www.dovecot.org/list/dovecot/2007-January/018376.html Which made it sound like the sieve plugin 1.0.0 had a bug that got fixed in 1.0.1. I am doing all of this on Gentoo, so I decided to just redo the ebuild so that I got the dovecot 1.0.0 ebuild, but with the sieve plugin 1.0.1. Aparently I get the same error and now am at a loss here. Any pointers? -A

[Dovecot] Testing IMAP clients with Dovecot, problems with MacMail
by Stewart Dean 04 May '07

04 May '07

I've been testing my user community's IMAP clients when I try to login and then transfer a big message from the inbox into a folder in an overquota folder directory. I am using native filesystem quotaing in AIXV5.3 with UWIMAP and comparing my results with what I see with Dovecot 1.0.0. (My Dovecot built without any plugins or quota extensions) Everything matches/works except for Mac Mail under SSL with Dovecot.. Mac Mail: 1) with UWIMAP, login and mailbox load goes OK, then the illegal overquota xfer fails (as it should) with a popup reading 'Message could not be moved', with (port 993) and without (port 143) SSL 2) with Dovecot, 1) login and mailbox load goes OK to port 10143, plain listen, and the illegal xfer correctly fails as it should with a popup messge under a plain connection, but 2) When the port number is set to the Dovecot ssl_listen port and the SSL box is checked, Mac Mail doesn't bring up the inbox and folders...it acts like it can't connect. Has anyone else seen this behavior, and is there a fix? Mac Mail is also known as Mail.app. I am testing it at 1.3.11 and 2.1.1. In the July '05 archive, I found this: > It looks like Mail.app treats "non-standard" ports differently. On the > standard port (993), the "SSL" option seems to do pure SSL; but with > another > port specified, it does clean-plus-starttls (and hence fails horribly, > because > it's talking to a pure SSl service) Is there anything I can do to get MacMail to behave correctly? Or will it clear up when I shut down UWIMAP and give Dovecot the default ports. A Bronx cheer for Mac Mail........ My thanks in advance, S. Everything else I tested behaves...for anyone that's interested....... ================ Over Quota Xfer results ==================== Insecure Pine from Unix login shell: refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. It is presumed that this will be used from within an SSH session to secure the transmission. Webmail (horde, insecure and secure) : refused by both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps. PC: TBird 1.5, 2.0, Sea Monkey and Netscape 7.2: get a popup with both UWIMAP (cannot exceed user or group quota) and Dovecot (there's not enough disk space.) server apps, both secure and insecure Mac: Seamonkey: ditto, same as PC Sea Monkey Mac Mail or Mail.app only works insecure, as per above

[Dovecot] Does dovecot do any address checking or referring back to a server?
by Wade Smart 04 May '07

04 May '07

This is a dovecot question so bear with me. I just upgraded to Ubuntu 7.04 from 6.06. I used fetchmail and postfix but not dovecot on 6.06. Fetchmail retrieved my mail and postfix put it in my maildir. I used Evolution to access the maildir directly. I setup Evolution to send mail directly as well. With this move I decided to go the extra step and get dovecot working. With some help on this form, I did that. But, I immediately started having trouble with getting my mail. Fetchmail is retrieving it but postfix keeps not processing for some reason. Im geting these error message: May 2 17:14:11 wadesmart postfix/qmgr[14778]: 6D4AD14286F3: to=<wadesmart(a)mail.wadesmart.com>, orig_to=<wade@localhost>, relay=none, delay=9331, delays=9307/25/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtpout.secureserver.net[64.202.165.58]: Connection timed out) The thing is - Im not sending mail at all through postfix. So my question is, I know that dovecot only serves up email to a mail client but, does it do something that I have totally missed that would some how or some way refer mail back to a server? Is there some type of address check or something going on? I know Im grasping at straws here but, I have been unable to get help from the postfix list or any list for that matter so if I can eliminate one more piece of the puzzle, all the better. Thanks.

[Dovecot] Dovecot SASL for postfix: Client host rejected: when relaying using POP mail client
by Nad 03 May '07

03 May '07

Hi everyone I have setup an ISP style mail system using postfix, dovecot, squirrelmail and mysql on ubuntu server 7.04. Everything seems to be working fine with sending recieving emails but relaying on submission service (port 587). I want to allow any client to be able to relay as long as they AUTH using dovecot SASL and are valid users regardless of what IP/host they come in from.

[Dovecot] Any plans for storing messages on a database?
by Francisco Reyes 03 May '07

03 May '07

Redudancy and recovering from a mailstore failure is one of the concerns I am trying to address where I work. Any plans to have Dovecot store emails in a database? NAS/SAN devices which do automatic replication to a second device are extremely expensive. I also don't see any distributed filesystem which is mature and available for the OS we use (FreeBSD). I recall at one point, many months back, Timo mentioned that perhaps storing the messages in the database was a possibility for the future. Any additional thoughts on this?

[Dovecot] Migrate from mlbox to maildir, lock problem
by Sylvain Nemtua 02 May '07

02 May '07

Hi We've been using dovecot successufly for few month. Previous setup : solaris 8, postfix+LDA, mbox + index on NFS (Netapp), 2500 accounts Everything shared overs NFS, multiple servers connect to index, mbox. mail_location = mbox:/var/mail/mbox/%u:INBOX=/var/mail/%u:INDEX=/var/mail/indexes_dovecot/%u We had at first some issue with mbox locking, using lock_method = dotlock solve the issue. The problem seemed to be with fcntl. I Migrate to maildir to ease administration to use maildir quota I use mb2md-3.20.pl to migrate the mbox everything works smooth. Actual setup : solaris 8, postfix+LDA, maildir + index + control on NFS (Netapp) I change the mail_location settings to mail_location = maildir:/var/mail/maildir/%u:INDEX=/var/mail/indexes_dovecot/%u:CONTROL=/var/mail/dovecot_control/%u And now I'm facing new locking issue : Errors on user loging, users leaving mail on server downloading the same mail over and over.

[Dovecot] How to use option allow_nets?
by Bernd Kuhls 02 May '07

02 May '07

Hi, according to http://wiki.dovecot.fi/PasswordDatabase/ExtraFields/AllowNets there exists an option allow_nets to restrict IP ranges from where users are allowed to login to Dovecot. I am using Debian Etch with the official Dovecot packages: # dpkg -l | grep dovecot ii dovecot-common 1.0.rc15-2 ii dovecot-imapd 1.0.rc15-2 ii dovecot-pop3d 1.0.rc15-2 using a mostly unchanged dovecot.conf. I tried to add the line allow_nets=127.0.0.0/8,192.168.0.0/16 in the block passdb pam { which is the default enabled auth code in Debian. When starting Dovecot I get this error message: # /etc/init.d/dovecot start Starting mail server: dovecot Error: Error in configuration file /etc/dovecot/dovecot.conf line 777: Unknown setting: allow_nets According to the Dovecot changelog > 2006-02-27 18:46 Timo Sirainen <timo.sirainen(a)movial.fi> > > * src/auth/: auth-request.c, auth-request.h: Added "allow_nets" > extra field. If set, the user can log in only from within the > given networks (hope the code is correct...) the option exists since February 2006, while the Debian package was released in December 2006. What I am doing wrong? Using TCP wrappers instead seems not to be an option according to http://dovecot.org/list/dovecot/2006-April/012476.html Greetings, Bernd Kuhls

[Dovecot] Best authentication option
by Eric 02 May '07

02 May '07

Dear Dovecot experts, I have a small home server debian based, with postfix/dovecot/squirrelmail installed locally and working. Dovecot is used non-secured (no imaps) but only on the 192.168.0.100 address (address of the server on the local network). I want to use squirrelmail to read my email from outside. Squirrelmail can configured to access it in particular, either through cram-md5 or login auths. In that situation, is it better (I mean more secure) to use : 1) auth mechanim = cram-md5 or 2) auth mechanism = plain (using PAM authentication for dovecot) ? That will determine my dovecot configuration. Thank you Eric

[Dovecot] Strange directory created at dovecot launch
by Eric 02 May '07

02 May '07

I installed dovecot from scratch and compiled it from 1.0.0 source. Installed in /usr/local. Now everytime I launch dovecot it creates and uses /usr/local/var/lib/dovecot and /usr/local/var/run/dovecot directories. For the latter I found the modifications to do in dovecot.conf for using /var/run/dovecot instead, but for the former I see nothing about such directory in dovecot.conf. What happens ? How can I configure it so that dovecot uses /var/lib/dovecot instead ? Thank you Eric

[Dovecot] Migrate from dovecot to dovecot.. new server
by Lars Johansen 02 May '07

02 May '07

Hi We have been running a dovecot server for some time.. users connect with pop. Now this server is going to be substituted with a new one.. before we used mbox, but now we will move to maildir! I have done some testing transfering the mail with the mb2md script, the conversion works correctly, but users gets duplicates since they selected "keep mail on server" I have googled for the problem, and set pop3_reuse_xuidl=yes and pop3_uidl_format = %08Xu%08Xv is the same on both servers.. but no luck. My first tought was to script in an X-UIDL header for each mail that was converted.. but that wont work since the mail already downloaded by the client didnt contain that header.. is there anyone that has some experience with this, or knows if its possible? Many Greetings, Lars Johansen
