[Dovecot] imap catches sig 11 on EXPUNGE
by Thomas Lofgren 10 Jan '05

10 Jan '05

Debian unstable, x86 # dovecot --version 0.99.12 # tail /var/log/mail.log ... Jan 6 16:56:55 gecko dovecot: child 16505 (imap) killed with signal 11 ... When I use squirrelmail, the imap process always segfaults when I try to enter my INBOX group. Squirrelmail produces the following error message: ERROR : Connection dropped by imap-server. Query: EXPUNGE When I use gnus, I can enter the group just fine, but gnus/emacs hangs on exit (100% reproducible, as is the squirrelmail case). Turning on debug info I catch this in the imap log: 37 UID SEARCH UID 1098 NOT SINCE 30 DEC 2004 * SEARCH 37 OK Search completed. 38 EXPUNGE read:errno=0 (hangs until emacs is killed) So in each case, it seems to happen on EXPUNGE. I got it to produce a core file, and this is the backtrace: (gdb) where #0 0x08071a58 in mail_index_lookup_field_raw () #1 0x080666b6 in mbox_mail_get_location () #2 0x08063111 in mbox_is_valid_mask () #3 0x08063553 in mbox_expunge_locked () #4 0x0806a9c3 in index_storage_expunge () #5 0x08051cc6 in cmd_expunge () #6 0x08054ae9 in _client_reset_command () #7 0x08054b78 in _client_input () #8 0x0808b108 in io_loop_handler_run () #9 0x0808aa98 in io_loop_run () #10 0x0805ac29 in main () Please let me know if I can provide any further information.

[Dovecot] migration from bincIMAP
by RYAN vAN GINNEKEN 10 Jan '05

10 Jan '05

Hello all I am using Freebsd 4.10stable, postfix 2.1.5 with SASL and TLS, procmail version 3.22 and binc IMAP 1.2.8 binc uses IMAPdir style mail boxes, Spam assassin, and ClamAV. Wish to convert to dovecot but your program does not support IMAPdir does it??? also i have many user accounts that i wish to use untouched if possible. I guess this is a migration question for the most part i am switching to dovecot because of its ability to use postgre database files and real log file. Is there a simple way to achieve this without losing any of my users mail? -- COMPUTER KING for all your computer needs http://www.computerking.ca email luck(a)computerking.ca phone 403-613-LUCK (5825) Hosting, Networking, Disaster Recovery, and Virus Removal solutions fit for royalty.

[Dovecot] Where are flags stored?
by Adam Pordzik 10 Jan '05

10 Jan '05

Hello, I don't now wheather this is IMAP or actually dovecot-specific, but I hope you people here knows about this at least: Where are flags like seen/unseen or e.g. message-priority stored? My goal is to mark spam or other filtered by procmail as "seen", so that dovecot doesn't notify MUAs about new mail in IDLE mode. Are there any mail-headers, so I can set these with procmail to accomplish that? Thanks for help, A

[Dovecot] Repair/Cleaup Maildir
by Glen Eustace 10 Jan '05

10 Jan '05

After having fought an issue with Courier-imap on FC3 for a week (that is still unresolved), I decided to try Dovecot instead. So far, fingers crossed, the issue has not re-occured. Migrating from courier-imap/sqwebmail to Dovecot/Squirrelmail was reasonably painless but I now have an problem. Is there a utility available to cleanup/repair the maildir tree for each user ? As part of the migration, I copied all of the courierimapsubscribed files to .subscriptions and removed the leading 'INBOX'. This seemed to be enough to get things going. Unfortunately, people who had only ever used webmail didn't have a courierimapsubscribed file. When they next used squirrelmail, a new .subscriptions file was created but didn't contain their folders. I tried to fix this by recreating the subscriptions file for each user and adding in all the .directories in their maildir root. I now have a maildir hierarchy with lots of crud in it. I need a utility to go through and deleted all the files that shouldn't be there anymore and to ensure that the subscriptions files are correct. Does such a utility exist ? If not, can anyone tell me where I can find a good description of what Dovecot expects to find in maildirs so I can write one myself. Any suggestions/help appreciated. -- =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Glen and Rosanne Eustace, GodZone Internet Services, a division of AGRE Enterprises Ltd., P.O.

[Dovecot] Extremely Slow Pop3 Downloads, Evolution 2.0.2
by Michael Joy 10 Jan '05

10 Jan '05

Hello All, We've been running Dovecot for imap for quite some time and have had little trouble with it. However, we recently switched over to using dovecot for pop3 because of simplicity as well as security issues with the older UW based pop server. I've noticed one serious problem. The only client that seems to have any issue at all with the server is Evolution. In pop3 mode, it takes a minute or more to download a few messages on an inbox with 400+ saved messages in it over gigabit ethernet. Over a DSL connection using MS Outlook 2k3 it takes about a minute total for all messages. Similarly with KMail it takes about 5-10 seconds to download all messages in the pop3 box. The messages trickle in with evolution 2.x, I've tried 2.0.0, 2.0.1, and 2.0.2 and all have this problem. I haven't tried the 1.x series as I don't have any linux boxes that old available to test. So apparently, there's two things of concern. 1. The server is definitely fast enough to handle the large mail box. 2. There's some serious incompatibility in Evolution/Dovecot causing for the 14.4 modem email download speeds over lan. We're running Dovecot 0.99.12 on Debian unstable, however 0.99.11 exhibited this behavior as well. If anyone has some hints, I'd greatly appreciate it. It's annoying having to wait 5-10 min to download mail in the morning when one gets into work ;) If there's any other information I can provide, please ask. Thanks to whichever kind soul finds time to trudge through this problem with us. Michael D. Joy HEP - University of Mississippi mdjoy(a)phy.olemiss.edu

[Dovecot] Cannot access a file with Mulberry from a dovecot server if the mail does not end with a newline character.
by Sven Kirmess 07 Jan '05

07 Jan '05

I use Mulberry 3.1.6 on Windows to read my mails with dovecot 0.99.12 Solaris 9. There are some mail which I cannot read. When I try to open such a mail, dovecot quits and restarts (I can see that with ps, nothing is logged). The Mulberry log just looks like this: | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00009 FETCH 695 (BODY.PEEK[1]) | * 695 FETCH (BODY[1] {61} | | --> #7.2300 Sun Dec 19 12:59:33 2004 | * OK dovecot ready. | | --> #7.2300 Sun Dec 19 12:59:33 2004 | A00001 CAPABILITY | * CAPABILITY IMAP4rev1 SORT THREAD=REFERENCES MULTIAPPEND UNSELECT LITERAL+ IDLE CHILDREN LISTEXT LIST-SUBSCRIBED NAMESPACE AUTH=PLAIN | A00001 OK Capability completed Looks like it just restarts the connection. The interesting thing is, that I can access the file with Netscape 4.8 via dovecot. The problem is the following: I copied the file in the Maildir directory, opened the copied file with vi and saved it. Now, I run a diff: | $ diff orig:2,S copy:2,S | Warning: missing newline at end of file orig:2,S | 12c12 | < <http://forums.mtgnews.com/attachment.php?attachmentid=35559> | --- | > <http://forums.mtgnews.com/attachment.php?attachmentid=35559> As you can see, vi adds the newline on the last line automatically if you save the file. Now, Mulberry/dovecot is able to read this file. I'm not sure if this is a dovecot or Mulberry problem. btw: This problematic mail was created with Mulberry 3.1.6. ;-) Sven

[Dovecot] Feature-request: ip based access control (libwrap)
by Bengt-Arne Fjellner 07 Jan '05

07 Jan '05

Is there plans to use libwrap Or is there already some kind of access control i have missed?? What i really want is a mechanism so i can say: If The request comes from "123.121.212.0" dont offer ssl and accept plain else demand ssl and no plain I now have this (almost) in another imap server by xinetd and two ip addresses. I could solve this by iptables or access list on the router but i would prefer to have it in the software itself.

[Dovecot] Japanese Search
by Kazuo Moriwaka 07 Jan '05

07 Jan '05

Hello, I'm trying to debug search command with Japanese 'ISO-2022-JP' codec. ISO-2022-JP codec needs to keep character cases until convert to UTF-8. For example: * '\033[$B%s\033[(B' means a character sounds 'N' * '\033[$B%S\033[(B' means a character sounds 'Bi' It causes a trouble in searches with Japanese. I found imap/imap-search.c/add_new() makes strings uppercase and fixed. But search results didn't affected.. ;-) I hope I can fix this problem in a few days. But I'm not clear about dovecot's source. If you have hints, please tell me. thanks, -- Kazuo Moriwaka moriwaka(a)valinux.co.jp

[Dovecot] Using Dovecot with Thunderbird 1.0 on Macintosh
by Rick Flower 07 Jan '05

07 Jan '05

Hi.. (and Happy New Year).. I tried switching over from Apple's Mail client (applemail) that is part of Panther to using Thunderbird 1.0 and find that all of the folders in my imap mailbox are messed up. Below is what Thunderbird is claiming the folder structure looks like : Inbox Arch Archiv Archive BMW Co E-Bay M Miscellaneous ML Bargains CKF Que Sof Sonn Ideally, the way it looks in Applemail looks more like the following: Inbox Archive BMW CarFax Coupons E-Bay Miscellaneous ML Bargains CKF [and a bunch of others that were missing from Thunderbird] Nextel OpexLD Palm Paypal Quest SW Realtors Registrations+Purchases Schoolpop ... [others] Software Updates Sonnet ... [others] Any ideas on what is going on here? I just moved to DoveCot 0.99.12, but it doesn't appear to make any distance. Also, if I try to pull up any of the weird folders in Thunderbird, it of course complains about the folders not existing.. Any ideas on how to get around this would be much appreciated! Thanks! -- Rick

[Dovecot] possible bug with mail->get_header and caching?
by Johannes Berg 06 Jan '05

06 Jan '05

I don't know if this is intended or not, but here it comes. I have * that copy plugin I was working on * dovecot 1.0-test59 * thunderbird test client My copy plugin looks for the X-DSPAM-Signature header line, and reports it to syslog as such: imap: we have a signature: "X-DSPAM-Signature: <sig>" where <sig> is replaced by what is found in the header line. This only happens when I copy in/out of the SPAM folder (which works fine). Now, when a mail is copied from INBOX to SPAM that doesn't have the signature line, I return an error to the client saying the user can't do that copy since the signature line is necessary. I detect the condition of not having that signature line by checking like this: if (!(signature = mail->get_header(mail, "X-DSPAM-Signature")) { ... return error ... } This works fine, error comes back. Second try, copying a mail that has the header line: works. So, lets do some code changes, disconnect and reconnect to reload the plugin. All of a sudden, copying mails that don't have the header line works too! Uhh? Lets go looking at syslog: imap: we have a signature: "X-DSPAM-Signature: " The only rational explanation I could come up with is that dovecot caches the header line and somehow decided that since it knows about the X-DSPAM-Signature header line mails that don't contain it should have an empty version of it. Well, I can of course test for this (and I actually should anyway, an empty signature isn't useful to dspam), but I do think this is a bug since it makes distinguishing between empty and non-present header lines impossible.

[Dovecot] PostgreSQL user database
by Marco Herrn 06 Jan '05

06 Jan '05

Hi, I am using postgresql for my password and user databases. The problem is, that the information needed in the user database is held in more than one table. But it seems to me that dovecot expects to get all the information for mailbox, uid, gid and home in _one_ query. Is there a way to get around this? Maybe even getting some of this information by another way than pgsql (this is more a rethorical question, since I have this information in the DB, but sometimes it is useful to get, for example the location of the mailbox by another way than the uid and gid). But my primary question is if I can set these fields in different queries.

[Dovecot] virtual hosting
by Tom Allison 06 Jan '05

06 Jan '05

I'm trying to figure out how I might set up some virtual hosting accounts for my server. domain1 would be delivered via procmail to ~/Maildir mail directories domain2 would be delivered via postfix to /var/mail/vhosts/domain2/username and similarly for additional domains. There's also one domain that's delivered to another machine, but that's not a dovecot issue. I just mention it for completeness. currently I have only domain1 and only: default_mail_env = maildir:~/Maildir I'm not really sure how to set this up for additional locations of maildir:/var/mail/vhosts/%d/%n/Maildir (This seems right?) Right now I'm wondering if I have to do one of the following: create two instances of dovecot with seperate configuration files? move everything to /var/mail/vhosts/%d/%n/Maildir data structure and the rewrite all my local (~/Maildir) procmail rules to manage delivery.. This is seeming sticky?

[Dovecot] 0.99.1[12] IMAP problems with Apple Mail.app?
by Jim Tittsler 06 Jan '05

06 Jan '05

Is anyone else having trouble using the Apple OS X Mail.app with a Dovecot IMAP server? With 0.99.11 and 0.99.12 attempting to read certain messages using IMAP or IMAPS seems to put Mail.app into spinning pizza of death mode. Sniffing the connection, it looks like it happens after the client issues a BODY.PEEK[] and the server has responded with the (UID XXXX BODY[] {YYYY}...) and OK Fetch completed. I've only been able to catch it happening with messages that are either (a) Base64 encoded or (b) those that claim to be multi-part/alternative, but only seem to contain a single part. The client acts like it has received the message, since if I kill Mail.app and restart it, I am able to read the problem message from its cache. Is this a Mail.app bug? Is it something about the way Dovecot is responding to the BODY.PEEK[] in these cases? Using Mail.app with the Novell myrealbox.com IMAP I haven't seen problem, even with a test problematic message I redirected there, although admittedly I'm changing the headers by doing the redirection. I haven't gotten 0.99.13rc3 to get past the autotools stage of complaining about AM_ICONV (and a number of AC_ warnings), so I've yet to try it.

[Dovecot] Internal login failure

I have discovered an odd problem; some users are able to connect to Dovecot either via pop3 or imap without any problems. Other users, however, aren't, and the following message appears in /var/log/mail.log: --- dovecot-auth: Login process 13 connected dovecot-auth: Login process 13 sent handshake: PID 1313 pop3-login: Internal login failure: user(a)mydomain.tld [195.242.16.30] dovecot: child 1311 (auth) killed with signal 11 --- I'm using Dovecot 0.99.11 (Debian Sarge), and all user information is stored in an LDAP database. Any suggestions? Thanks, :Peter

[Dovecot] imap client library.
by Oon Arfiandwi M. 06 Jan '05

06 Jan '05

Dear Dovecot developers, I have several question about imap client: - Is there any difference if we want to create imap client that connect to Imap server with user mail format Mailbox or Maildir? Dovecot support both of them, are we need to create different imap client to support both of them? - Does anyone have imap client library other than UW's c-client? thanks for your information, -- Oon Arfiandwi M.

[Dovecot] authenticate authenticated users
by Tzafrir Cohen 05 Jan '05

05 Jan '05

Hi I'm using dovecot on a LAN server. I sometimes read mail from the server itself locally with mutt and sometimes remotely with mutt or mozilla . I would like to avoid typing my password whenever necessary but without writing a plain-text equivalent copy of it locally. It feels quite silly to have to type the password locally becase the imapd does not know that the process is indeed a process of the user tzafrir. It has all the information it neeeds to check that. wu-imapd has something called "pre-authentication": the imapd is run by the user unpriviliged to access mail in the user's home directory. As a bonus this works quite nicely with ssh public key authentication. I know that at least mutt and pine support running a custom command for creating an imap connection. But then again, wu-imapd is built quite, well, differently. Any ideas? -- Tzafrir

[Dovecot] compact folders, expunge, etc
by Mail Admin 04 Jan '05

04 Jan '05

Test58 and test59 breaks "compact folders" and "expunge" in thunderbird and evolution. Messages marked for deletion just sit there as if compacting folders or expunging have no effect. Thunderbird continues to behave erratically with dovecot test builds. I haven't been able to test the imap_client_workarounds=tb-negative-fetch option yet as I'm still running test52. Thunderbird displays blank messages when they are opened, but "Edit as new" shows the message contents. Thunderbird also displays messages that appear to be truncated like: > Hi Peter, > > I will not This body part will be downloaded on demand. Thanks, Derek

[Dovecot] PLAIN-MD5 passwords?
by Peter Clark 03 Jan '05

03 Jan '05

After I found out that {CRYPT} doesn't support passwords longer than 8 characters, I decided to switch over to MD5 for user passwords in my LDAP database. However, while I have no problem with Postfix + SASL, Dovecot fails to authenticate. Relevant bits from /etc/dovecot-ldap.conf: user_attrs = mailAddress,,,,, # The search string is identical to what's found in /etc/saslauthd.conf: user_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) pass_attrs = mailAddress,userPassword pass_filter = (&(|(uid=%u)(mailAddress=%u))(status=active)) default_pass_scheme = PLAIN-MD5 When I try to connect using either KMail or SquirrelMail (which worked just fine before I switched schemes), the following error appears in /var/log/syslog: ldap(user(a)mydomain.tld): password mismatch But when I try 'testsaslauthd -u user(a)mydomain.tld -p longpassword' it authenticates just fine. I have the line 'password-hash {MD5}' in /etc/ldap/slapd.conf, and I used 'slappasswd -h {MD5}' to create the MD5 versions of the passwords. Dovecot is v. 0.99.11. If I can't figure out how to get it to work with MD5, I guess I'll have to go back to CRYPT, but it would be nice to have longer passwords... :Peter

[Dovecot] Wanted: gnutls11 support
by Jaldhar H. Vyas 03 Jan '05

03 Jan '05

I talked to Timo about this before and even provided the beginnings of a patch but don't have enough time to really do a proper job. Anyway, dovecot doesn't work with recent versions of the GNU TLS library. As a result, I compile the Debian package with OpenSSL. However some of the other libraries used, such as OpenLDAP are linked against GNU TLS so Dovecot is linked against both. And it is suspected this is leading to bugs. So could some kind soul provide Timo with a patch he can include in 0.99.13? -- Jaldhar H. Vyas <jaldhar(a)debian.org> La Salle Debain - http://www.braincells.com/debian/

Re: [Dovecot] Maildir owner importance

That last line actually made it possible for me to be able to log into the server :) I am still getting errors from PAM but it starting to look good. Is there a good HowTo on setting Dovecot to comunicate directly to MySql without using PAM in the middle ? Also, Since Postfix is still not working on my server, I can't actually recive Emails. Is there somewere an example of the files that need to be in the maildir that I can put them in there and test that the email client get's the mail out ?

[Dovecot] SASL AUTH
by Tom Allison 02 Jan '05

02 Jan '05

I'm reading through the dovecot wiki pages for virtual hosting with postgresql/postfix/dovecot/debian and it looks pretty nice but I think I'm going to skip the SASL authentication since I'm in a trusted network. I think all I need to do is skip section 5 entirely and bypass all the sasl references in the postfix section. Technically, I don't think any of the SASL has much to do with the dovecot configuration.

[Dovecot] random pool depletion
by Johannes Berg 31 Dec '04

31 Dec '04

I'm facing a problem with dovecot 1.0 test-59; ever since I installed it and use it my random pool is always depleted whenever someone opens an imap connection. This wouldn't be too bad if the machine was used interactively, but since it is not and other services read directly from /dev/random those are sometimes blocked due to dovecot depleting the pool by reading /dev/urandom. Thus my question: is it really necessary to use random numbers from /dev/urandom for temporary filenames? And even if, couldn't it use less? It apparently uses 8 bytes every time. johannes

[Dovecot] Authentication difficulties
by Timo Sirainen 30 Dec '04

30 Dec '04

There are constantly pretty basic questions in this list (and in my inbox) about how to get user authentication work correctly. This means that the documentation how it all works is either bad, or people don't find it easily. Any ideas how to improve it? I did this now: - Documentation link in dovecot.org now points directly to Wiki, so people don't go read the outdated documents - Upcoming 1.0-tests and 0.99.13 will contain doc/USE-WIKI-INSTEAD file pointing to Wiki: http://dovecot.org/list/dovecot-cvs/2004-December/003928.html - Updated comments in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003924.html - Added pointers to Wiki in dovecot-example.conf: http://dovecot.org/list/dovecot-cvs/2004-December/003927.html How good are the Wiki documents about user authentication in general? The content should probably be split somehow to "getting started" vs. "everything there is to know about it" and "system users" vs. "virtual users". I'm not really sure how to best do that though. I think the Wiki in general could be better organized. Wish I knew how.

[Dovecot] Maildir owner importance
by Roi Efrati 29 Dec '04

29 Dec '04

I have set up a directory (/var/local/virtualdir/) as the maildir with a special user/group (virtualmail) and in it I create directories for each domain (example1.tld, example2.tld etc) and sub dir's for each mailbox). Only at the moment, apart from the first one, they are all created as with user root as the owner. How important is to have all the directory tree owned by the same user group (virtualmail:virtualmail) ?

[Dovecot] bug in 99.13-rc2 in ldap md5 patch

hi, it takes me another hour do debug it again, although i already report it for both joshua and timo. the original patch for openldap's md5 crypt has a small bug. in passdb-ldap.c the schema is already PLAIN-MD5 since that was set in the other part of the original patch in password-scheme.c. do anybody use dovecot with ldap and md5 password? i don't think so:-( this patch would be useful to apply before the final 0.99.13. anyway in the current 1.0 series the PLAIN-MD5 and LDAP-MD5 schema are different. at least plain_md5_verify and plain_md5_generate differ from ldap_md5_verify and ldap_md5_generate. why? -- Levente "Si vis pacem para bellum!" --- dovecot-0.99.13/src/auth/passdb-ldap.c.lfarkas 2004-12-22 17:06:25.000000000 +0100 +++ dovecot-0.99.13/src/auth/passdb-ldap.c 2004-12-22 17:06:56.000000000 +0100 @@ -109,12 +109,11 @@ } /* Special case for OpenLDAP's MD5 type */ - if (strcasecmp(scheme, "MD5") == 0) { + if (strcasecmp(scheme, "PLAIN-MD5") == 0) { buf = buffer_create_static(data_stack_pool, 16); if (base64_decode(password, strlen(password), NULL, buf) == 1 && buffer_get_used_size(buf) == 16) { password = binary_to_hex(buffer_get_data(buf, NULL), 16); - scheme = "PLAIN-MD5"; } }

[Dovecot] Moving existing MD5 passwords to LDAP?

I have a dovecot installing working quite well for around 1000 users using passwd-file authentication. I'm moving to LDAP and would sure love to be able to migrate the existing MD5 passwords. I've tried using ldapmodify to set "userPassword" to {CRYPT}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 and {MD5}$1$H8JE0k5X$y.ptShgYbOgWF.99lX88N1 In both cases, ldapmodify exits without errors but I cannot bind using the new password.

[Dovecot] bidirectional synchronization of dovecot-managed maildirs
by James Leifer 28 Dec '04

28 Dec '04

Hello and happy holidays, I've been thinking about high performance bidirectional synchronizing the mail on my laptop (which is frequently disconnected) and my workstation at work (which is always on and receives all inbound mail). Both run dovecot on top of maildir. I've been playing with offlineimap, unison (which I already use for all my non-mail files), as well as the gnus agent (in IMAP "disconnected mode"). None of these solutions is really satisfactory: * offlineimap treats a message refile between folders as a delete-plus-resend; * unison doesn't understand the semantics of flag changes at the end of files in maildirs; it also has to stat all the files (which can become slow) to detect changes; * gnus agent can't refile messages between folders when in disconnected mode. Perhaps there are better disconnected IMAP modes available for other MUAs, but, it seems like a more general solution would be appropriate. In particular, the "uniq" field of a maildir filename is an easy way of tracking the identity of a message as it gets refiled. My question: would it be difficult to patch dovecot so that it maintained the *same* uniq when copying messages between folders? What about adding hooks that get triggered whenever dovecot copies or deletes messages? These hooks could log the changes. Later, when one tries to sync, one merges the changes from both replicas and then applies them. I'm aware that dovecot has an option to do copies as hardlinks, which is a good start, but still requires one to stat the files to discover which have the same inode. This is *much* slower than simply listing the directories and comparing maildir "uniq" fields. I'm aware that this invariant wouldn't be maintained if other programs modified the maildirs under dovecot's nose, but I'm willing to exclude this possibility. Suggestions? Best regards, -James Leifer

[Dovecot] dspam plugin
by Johannes Berg 27 Dec '04

27 Dec '04

The first version is available at http://johannes.sipsolutions.net/edit/Projects/dovecot-dspam-integration/co… I'm calling dspam for every message, that seemed easier for now. I will probably integrate Tom's idea about storing the messages until a cron-job picks them up at night by just storing signatures into mysql, in which case its easy to do with a single query: INSERT INTO new_spam (user, signature, isspam) VALUES (<user>, <signature>, <isspam>) ON DUPLICATE KEY UPDATE isspam = <isspam> with given values for <user>, <signature> and <isspam> and a key on (user, signature). For now, however, calling dspam for every message works good enough for me, and seems to work. Regards, Johannes
