[Dovecot] Dovecot and Outlook Express "plaintext authentication not allowed..."
by D Chen 18 Apr '12

18 Apr '12

Server: Ubuntu 11.10 server with postfix (MTA), dovecot (MDA) Mail client: Outlook Express in Windows XP with IMAP on port 143, SMTP on port 25 When tried to set up a new Outlook Express mail acct, the following error encountered: Your IMAP server wishes to alert you to the following: plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. When asked "would you like to download folders from the mail server you added?" then got the following error: The server has rejected your login. Please verify that your user name and password are correct. I re-entered several time with the correct username and password, but still responded the same error. Any insights would be greatly appreciated.

[Dovecot] vacation plugins for squirrelmail
by Daminto Lie 18 Apr '12

18 Apr '12

Thank you folks for your replies. I realised that the dovecot 1.2.9 that I installed via ubuntu synaptic package manager has already come with sieve plugins. After making some modifications on the dovecot.conf file, I went to download and install avelsieve 1.0.1 (stable version) onto the squirrelmail. Then, I run in squirrelmail conf.pl and added the plugin. I logged in and could see "Filter" option right on the top header row. I went to click it and nothing came up. I checked in the mail.log but did not see any errors there.

[Dovecot] Howto reindex with solr?
by Jean-Daniel Beaubien 17 Apr '12

17 Apr '12

Hi, I am currently testing a 2.1 dovecot setup with fts-solr. Search speed is simply amazing. I decided to try to delete and rebuild the solr indexes, but i can't seem to rebuild them thru dovecot. At first, when telnetting to the imap server, the search initially built the index, and then subsequent searches are blazingly fast. 1- I deleted all the solr indexes with the following query: <delete><query>*:*</query></delete> 2- Flag the mailbox to be re-indexed: doveadm force-resync INBOX At this point, it doesn't work. When I telnet into the imap server, the searches always come back empty 3- I also tried a few other commands: doveadm fts rescan, doveadm index INBOX. Still no search results. Nothing seems to be appearing in the logs when I issue all the doveadm commands. What did I miss? Thanks, -JD

[Dovecot] POP3 Dovecot Auth CPU usage 75%+
by Root Kev 16 Apr '12

16 Apr '12

Hello all, I hope someone can help me, I have been testing out Dovecot to switch from popa3d which I use at the moment. When I get several users connecting and disconnection multiple times, the Dovecot process with command Auth uses 50-90% of the CPU for the period which they are connecting. I am wondering if there is something that I may have misconfigured, or if there is something that I can change so that this spike doesn't occur. If anyone could shed some light on the issue, I would appreciate it, Kevin /var/mail# dovecot -n # 2.1.4: /usr/local/etc/dovecot/dovecot.conf # OS: Linux 2.6.32-33-generic-pae i686 Ubuntu 10.04.4 LTS ext4 auth_cache_size = 10 M auth_verbose = yes disable_plaintext_auth = no instance_name = Mail Popper 1 listen = 172.20.20.222 login_greeting = Mail Popper 1 Ready mail_location = mbox:/var/empty:INBOX=/var/mail/%u:INDEX=MEMORY mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = shadow } protocols = pop3 service pop3-login { service_count = 0 } ssl = no userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv }

[Dovecot] Better to use a single large storage server or multiple smaller for mdbox?
by Emmanuel Noobadmin 15 Apr '12

15 Apr '12

I'm trying to improve the setup of our Dovecot/Exim mail servers to handle the increasingly huge accounts (everybody thinks it's like infinitely growing storage like gmail and stores everything forever in their email accounts) by changing from Maildir to mdbox, and to take advantage of offloading older emails to alternative networked storage nodes. The question now is whether having a single large server or will a number of 1U servers with the same total capacity be better? Will be using RAID 1 pairs, likely XFS based on reading Hoeppner's recommendation on this and the mdadm list. Currently, I'm leaning towards multiple small servers because I think it should be better in terms of performance. At the very least even if one node gets jammed up, the rest should still be able serve up the emails for other accounts that is unless Dovecot will get locked up by that jammed transaction. Also, I could possibly arrange them in a sort of network raid 1 to gain redundancy over single machine failure. Would I be correct in these or do actual experiences say otherwise?

[Dovecot] Sieve pipe extension - can it retur something?

I have a question about sieve pipe: can it return something to further processing? For example in procmail I can do: --8<---------------cut here---------------start------------->8--- :0 VIRUS=`$CLAMSCAN --mbox --disable-summary --stdout -` --8<---------------cut here---------------end--------------->8--- and then test VIRUS variable. Maybe I missing something, when read http://hg.rename-it.nl/pigeonhole-0.2-sieve-pipe/raw-file/tip/doc/rfc/spec-… KJ -- http://sporothrix.wordpress.com/2011/01/16/usa-sie-krztusza-kto-nastepny/ Gloffing is a state of mine.

[Dovecot] Dovecot 2.1.4 and client certificates
by Бранко Мајић 14 Apr '12

14 Apr '12

Version: 2.1.4 OS: Gentoo stable/amd64 OpenSSL version: 1.0.0h I'm having a slight problem with the client certificates in Dovecot 2.1.4. I've set-up the client certificate verification/authentication, and it seems that Dovecot is choking on the trustchain with CRL's that I'm providing to it (attached to this mail). When I enable the client authentication using certificates, and pick the certificate from my client (I've also tried it out with gnutls-cli as well), I get the following errors in Dovecot's log: imap-login: Info: Invalid certificate: Different CRL scope: /CN=Example Root CA/O=Example Inc./C=RS As per the wiki2 configuration page, I've set up the truststore in the following order (everything PEM-encoded): Example Person CA Certificate Example Person CA CRL Example Root CA Certificate Example Root CA CRL Person CA is the one issuing the end-entity certificates, of course. I'm also attaching the certificate I've used for testing. On additional note, the imap-login process also got stuck writing out the error message to the log file, refusing to die when receiving the SIGTERM (had to send SIGKILL). A similar set-up used to work under Dovecot in Debian Squeeze (version 1.2.15). The same file copied over to Dovecot 2.1.4's configuration won't work. I've compiled Dovecot by hand, and I'm not running it in any kind of chroot (this is a developer set-up so I could add support for rfc822Name username extraction I mentioned a week or so ago without messing around as root).

[Dovecot] Compressed mbox - patch
by kjonca＠o2.pl 14 Apr '12

14 Apr '12

Some time ago I complained about very slow access to compressed mboxes. Unfortunately it looks like that it is very little interest in it, so I have to investigate some things by myself. Firstly: some rationale. Why do I prefer use mbox/maildir over mdbox. Short answer "bus factor" for support mdbox (not only dovecot) Longer answer: if something goes wrong withm maildir/mbox i can use other tools (mutt, or formail or even text editor) and with mdbox ... I am not ISP, I use dovecot as a "gateway" to my (rather huge) mail archive. Most of these mails are rather valuable for me, so I prefer use something "well-known-and-tested". (I can't do like most ISP's do: write in "Terms of Service" that mail can be lost or damaged and we give no warranty :) ) So then: Below my patch. It contains 2 changes: 1. when buffer is compressed, we try to save last marked offset. 2. Increase temporary buffer for decompression. without these changes 1.5 GB of bzip compressed mbox with ~20K messages can't be open in 1.5 day After applying 1. change it can be open in ~1.5 h With both changes it was a few minutes. Maybe it is a good idea to add config parameter to specify size of decompress buffer? Patch is against v2.0.18 -- Gdyby ktoś miał zbędny Toshiba G450 - to chętnie przejmę ;) < asuffield> a workstation is anything you can stick on somebodies desk and con them into using -- in #debian-devel

It works with me now that > I tried in a test server with OpenSSL in non-standard dir. Sorry, I didn't know that with "autogen.sh". Just grabbed Dovecot 2.1.2 (which is all properly set up - so I couldn't do anything wrong ;-) and compiled it. Compilation works. Great! The binaries find all their libraries. But two libraries are not quite okay. They don't find their SSL libs: libdovecot-lda.so libdovecot-storage.so Since libdovecot-lda.so doesn't contain the words libssl or libcrypto, I guess that ldd just complains because it uses libdovecot-storage.so. Thus, libdovecot-storage.so is the (only) one left with an incomplete library search path. Luckily, all binaries use some additional libraries which come with a proper library path. So the whole things works, but it's more like some kind of magic. It would be great if libdovecot-storage.so could be fixed as well to make things finally perfect. Thanks for all your effort. (I know this isn't top priority as most people use precompiled stuff and never run into such kind of things.) Greetings, Andreas

[Dovecot] [OT] Outlook identities
by Michael Orlitzky 14 Apr '12

14 Apr '12

Nothing to do with Dovecot, but I figured this is the best place to ask. Do any of the newer versions of Outlook have proper identities support like Thunderbird, mutt, Roundcube, i.e. every other mail client on Earth? We have customers who set up ten different mailboxes for one person because otherwise Outlook won't Do the Right Thing. Is there some way to make it behave like the others? * When sending new mail, you can choose which address to use. * When replying to mail, it sends from the address that the message was sent to by default. * All mail winds up in one inbox. Outlook (2003, 2007) does do this if you set up different mail accounts, but we shouldn't have to do that.

[Dovecot] Unseen messages question
by Antoine Nguyen 14 Apr '12

14 Apr '12

Hi list, this question is related to the IMAP protocol itself, not really to Dovecot. I'm trying to understand what is the more efficient way to maintain the number of unseen messages of the currently selected mailbox. RFC3501 says a client must not issue a STATUS command to the selected mailbox and that information sent by a SELECT is enough. My current idea follows these steps : * Issue a STATUS before the mailbox is selected => I know how many unseen messages it contains * SELECT the mailbox => I got the eventual first unseen message in this mailbox but I don't understand how this info can be useful * Maintain the unseen counter (on client side) according to what the user do * Send a NOOP command every X minutes and look at the RECENT response to see if there are new messages I think it works pretty well when the mailbox is opened only once. Let's imagine this mailbox is opened twice, by different clients. If one client marks a message as \Seen, how can the second client know about this change? Thanks for your help, Antoine Nguyen http://modoboa.org/

[Dovecot] How do I test if the anti spam plugin is working?
by Dr Josef Karthauser 14 Apr '12

14 Apr '12

I've configured the dspam anti spam plugin, but it doesn't appear to be doing anything when I move mail between mailboxes. Can anyone help me determine what's going on? The plugin appears to be loading; at least if I don't define all the required configuration options I get a complaint in the log file. But beyond that I don't see any activity. Here's the config: babel# dovecot --version 2.1.3 The dovecot anti spam plugin config is: protocol imap { mail_plugins = $mail_plugins antispam } and plugin { antispam_debug_target = syslog antispam_verbose_debug = 1 antispam_backend = dspam antispam_signature = X-DSPAM-Signature antispam_signature_missing = error antispam_trash_pattern_ignorecase = trash;Deleted * antispam_spam_pattern = SPAM antispam_dspam_binary = /usr/local/bin/dspam antispam_dspam_args = --deliver=;--user;%n@_%d } I don't even appear to be seeing any log entries from the plugin. I've moving an email from my main mailbox into a mailbox called 'SPAM', which is how I thought that it was supposed to be triggered. Cheers, Joe

[Dovecot] Problems with Apple Mail and attachments
by Helga Mayer 12 Apr '12

12 Apr '12

Hello, has anyone experiences with the Apple mail client, to be precise : Mail 5.2? When I copy a message with an attachment from the inbox to a different folder using 'move' or 'copy' , Apple Mail does not properly display the attachment in the new folder. When I copy the same message using 'archive' the attachment shows up properly. There is no difference on the server side. We are using maildirs. The raw messages in the various folders are identical. Deleting plist on the Mac didn't help. After removing and recreation of the account (client side) the attachments are displayed correctly again. Is this an apple problem or has it got anything to do with dovecot.index.cache ? Kind Regards Helga Mayer

It has postfix, dovecot 1.2.19, LDAP and squirrelmail as the webmail. I have also created virtual users accounts on the system through LDAP. I can send and receive mails which is great. Now, what I am trying to do is to set up a vacation auto-reply on the squirrelmail so that users who are about to go on vacation can set it up themselves. I was looking around for the vacation plugins for dovecot that I can incorporate it into squirrelmail. Any help would be very much appreciated. Thank you

[Dovecot] "doveadm mailbox status" destroys compressed messages without W= attribute
by Artur Zaprzała 12 Apr '12

12 Apr '12

I still have some old messages from previous mail server. This messages have no W= attribute either in file name or dovecot-uidlist and are compressed with gzip. Running "doveadm mailbox status -A vsize \*" will result in the following messages: doveadm(foo@domain): Error: Cached message size larger than expected (2580 > 1451) doveadm(foo@domain): Error: Maildir filename has wrong S value, renamed the file from /vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=2580:2,SZ to /vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=1451:2,SZ doveadm(foo@domain): Error: Corrupted index cache file /vmail/domain/foo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 2 doveadm(foo@domain): Error: Cached message size larger than expected (2580 > 1451) doveadm(foo@domain): Error: Corrupted index cache file /vmail/domain/foo/Maildir/.Sent/dovecot.index.cache: Broken physical size for mail UID 2 doveadm(foo@domain): Error: read(/vmail/domain/foo/Maildir/.Sent/cur/1206550323.M125837P13306V0000000000000812I0000809E.oldname,S=2580:2,SZ) failed: Input/output error (uid=2) (Size of uncompressed message is 2580 and compressed size is 1451) I have enabled zlib plugin for imap, pop3, lda and lmtp. But how to enable it for doveadm? -- Best regards, Artur Zaprzała

[Dovecot] SSL Certificate Anomalies with latest code changes
by Thomas Leuxner 12 Apr '12

12 Apr '12

Some change between bf5ae73e9475 and 584bd77c38fd seems to have broken something in the SSL Handshake. A previously valid server certificate is deemed invalid by various mail clients. http://hg.dovecot.org/dovecot-2.1/rev/bf5ae73e9475 works fine while http://hg.dovecot.org/dovecot-2.1/rev/584bd77c38fd does not.

[Dovecot] ldap idle connection timeout in DoveCot 1.0.13?
by Zhou, Yan 12 Apr '12

12 Apr '12

Hi there, We are using DoveCot 1.0.13, it connects to LDAP server for authentication. It seems that DoveCot keeps the idle LDAP connection open. Our firewall is terminating these connections after some time of idle activity (2 hours), then, we run into authentication problem. If we restart either LDAP or DoveCot, then it is fine. Can we set some kind of LDAP idle connection timeout in DoveCot? /etc/dovecot-ldap.conf. I do not see any configuration available for 1.0.13. Another alternative is to set idle connection timeout in LDAP, but we prefer doing that in DoveCot.

[Dovecot] lazy_expunge questions
by James Devine 11 Apr '12

11 Apr '12

I'm messing around with lazy expunge and I just had a couple of questions. If I delete messages or folders with messages, I see them being moved to the expunge namespace, but if I delete an empty folder, all traces of it seem to disappear. Is there a way to move empty folders to the expunge namespace also? My second question is in regards to restoring folders. If I try to execute the imap command 'RENAME EXPUNGED/TEST INBOX/TEST' I get 'NO [CANNOT] Can't rename mailboxes to/from expunge namespace'. Just wondering if this is possible or do I need to recreate the folder and then move messages into it.

[Dovecot] Bug tracker
by Timo Sirainen 11 Apr '12

11 Apr '12

I started thinking that perhaps I should move my TODO list to a bug tracker. But because of reasons I've explained a few times before, I don't want a full blown public bug tracking system. The requirements for it are: * I am the only person who can add new bugs. Everyone else reports bugs/requests to this mailing list as before. (Well, I guess Stephan could use this as well if he wants to.) * Everyone can comment existing bugs. * Dovecot mailing list integration: Commenting a bug sends a mail to the mailing list. Replies to those comments go back to bug tracker (probably based on some [#1234] tag in subject). I would have the option of adding a comment that doesn't go to the mailing list (= adding some internal comment that nobody else cares about). Notifications about new bugs won't go to the mailing list (most likely it was created due to a recent mailing list post). So the main difference to how things work now is that people would be able to easily browse existing bugs and add comments to them. I would add bugs there only when I'm not planning on fixing them within a few days. I wouldn't add each and every feature request there, only the things that I'm actually interested in developing. So the idea would be to actually get the bug tracker emptied at some point, not to be a graveyard of unimportant feature requests that about 1-2 people in the world would want. So, any suggestions for what software could do these things? I think Request Tracker has those features, but it's not really the nicest/prettiest thing.

[Dovecot] Proxy and SSO (single sign-on)
by Miguel Tormo 11 Apr '12

11 Apr '12

Hello, I have a running setup with a dovecot imap4/pop3 proxy to a few dovecot backend servers which actually store the mailboxes. This is running smoothly and allows me to transparently distribute mailboxes. I'm using some "extrafield" configured in the LDAP passdb. However, now I would like to use GSSAPI (preferred) and NTLM for single sign-on. Both are pretty straightforward to configure in a single instance environment, but I don't know if they would work with proxy. For example, with GSSAPI there are two cases: 1) Just use gssapi mechanism, without PAM. Then, it a user presents a ticket the passdb ldap is not used, so the extrafields are never read. 2) Use gssapi and PAM (thus allowing using a kerberos password). But the extrafields feature isn't available with PAM passdb driver, so again the proxy won't work. The case for NTLM would fall into the first case, I think. Am I right regarding this scenario? Is there a way I could make SSO and proxying work? I'm currently using dovecot 2.0.16 (had to patch it to increment LOGIN_MAX_INBUF_SIZE to 4096 for GSSAPI to work, as I read somewhere in this list), but I could upgrade to a newer version if that allows all this to work. Thanks!
