[Dovecot] Client workaround?
by David King 24 May '06

24 May '06

I have a phone (LG CU320) with a built-in IMAP client. However, it has some issues. For one, the phone crashes if there are greater than some-as-of-yet-determined-number-of folders. That can't be worked around at the server, but this one can: After a long session of staring at tcpdump, it appears that when it logs in it does so like this: a001 LOGIN "username" myPassword This works unless one has funny characters in their password (which is usually the case). Why on earth it would put quotes around the username and NOT the password is beyond me (which is more likely to have special characters?) It does seem to check the CAPABILITY line to see what authentication is supported, because if I try it with a different (cyrus) server, instead of using LOGIN to authenticate, it uses AUTHENTICATE Dovecot presents that it supports AUTH=PLAIN, whereas Cyrus presents that it supports AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5 AUTH=GSSAPI. This is presumably because Dovecot prefers STARTTLS or simple IMAPS for authentication. So as I see it, getting this phone work with Dovecot and a password with special characters can take one of two forms (either of which I'll be happy to code): 1. Somehow getting Dovecot to look at the second token as if it *were* quoted. 2. Getting Dovecot to present and interpret AUTH=LOGIN (i. e. AUTHENTICATE), which appears to cause the phone to properly escape the password The first one really only fixes certain special characters, and leaves others still broken (like quotes themselves), and in fact violates IMAP4rev1. So I'd just make and run a local patch The second one fixes the problem more cleanly, and my code can be reused and submitted to the Dovecot commiters. So my question to anyone familiar with the codebase is, which of these options is more likely to work, and would the Dovecot team be interested in patches for either one?

But in my experience, it's bad practice, both in the enterprise and in the service provider world. When your box gets hit with a denial of service attack, or 500 users decide to copy the latest cool video to their home dir, and it's also your mail and web server, all of your services go to hell. When you have a box dedicated to specific services, you can upgrade that box without affecting all of your services. If the box dies, not all of your services die. -- Roger J.

This is a very simple problem to fix, and doesn't require blocking port 22. Set up /etc/hosts.allow: sshd : 192.169.1.0/255.255.255.0 sshd-keygen-wrapper : 192.168.1.0/255.255.255.0 Set up /etc/hosts.deny: ALL: ALL:deny Tcpwrappers will now take care of you, and any DOS attacks you get will simply be dropped. > Do consider running your mail services off a machine that is not a Mac > OS X server.

While some of this statement may be accurate, there's a lot of FUD here too. Both OS X and OS X server use the same kernel, it is true. However, these operating systems are fast and reliable. We ran our mail server for a couple of years on OS X with exim and courier-imap, and the only reason we did stop and move to Linux is because we needed a bigger solution and intel-based hardware was cheaper than a bunch of XServes. And I will challenge your statement about high load. We have two web servers that average betwen 5 and 10 mbits of constant web load, running on OS X Server and XServes. The average load on these boxes is something like 0.20. Roger Weeks

[Dovecot] Busy, again
by Timo Sirainen 24 May '06

24 May '06

Just a note to people if you're wondering why I'm not replying to most of my mails: I'm trying to get into university to start stydying cellular biology (so I'm applying to biochemistry and biotechnology). Their entrance exams are next wednesday, so I'm trying to use most of my time left to study for them (and also do some work..). I don't know much about the subject, so I really need to study for them. :) Then again, if I don't pass, my fallback plan is to go in via computer science and try again next year. Hopefully they allow taking the same bio-classes even if it's not my major.

[Dovecot] Thunderbird 1.5 and messages with no Date: header
by grant beattie 24 May '06

24 May '06

hi, some of my Thunderbird users have a minor but annoying problem with messages that have no Date: header. these clients use BODY[HEADER.FIELDS (Date)] as the date for messages. when a message has no Date: header, they display the date as 01/01/1970 10:00:00 because Dovecot returns empty string. would it be possible for Dovecot to return INTERNALDATE instead, for messages that contain no Date: header? I know this is not *technically* correct, but it's a reasonable best-guess, and better than returning nothing. perhaps as a client-workaround? I vaguely recalled a previous message about this, but I couldn't find it today. grant.

[Dovecot] Shared folder (namespace) access hanging
by Jeff Turner 24 May '06

24 May '06

Hi, I'm using Dovecot 1.0-b8. We use a shared 'support' account for incoming support mail. For security reasons we want to instead have everyone with their own account, accessing a shared 'support' folder. So I've configured dovecot with a public 'Support' namespace: default_mail_env = maildir:/imap/mailboxes/%u namespace private { separator = / prefix = inbox = yes } namespace public { separator = / location = maildir:/imap/mailboxes/support:CONTROL=/imap/mailboxes/%u/shared-settings/support/control prefix = Support/ hidden = no } So now: - User 'support' logs in (this is the user whose folder is being shared). Dovecot creates a dovecot-uidlist file: root@redback:/imap/mailboxes/support/.INBOX.test# cat dovecot-uidlist 1 1147757548 9 1 1147755677.P8078Q3M183587.redback.sydney.atlassian.com:2,RSace 2 1147755677.P8078Q2M183587.redback.sydney.atlassian.com:2,abcdf 3 1147755677.P8078Q1M183587.redback.sydney.atlassian.com:2,Sabcd 4 1147756077.P8078Q8.redback.sydney.atlassian.com:2,Sabcd 5 1147756440.P8461Q3M643698.redback.sydney.atlassian.com:2,Sa 6 1147756440.P8461Q2M643698.redback.sydney.atlassian.com:2,Sa 7 1147756440.P8461Q1M643698.redback.sydney.atlassian.com:2,Sa 8 1147756440.P8461Q0M643698.redback.sydney.atlassian.com:2,Sa root@redback:/imap/mailboxes/support/.INBOX.test# ls -la total 60 drwxrwx--- 5 jturner mail 4096 May 16 15:32 . drwxrwxrwx 59 support mail 4096 May 16 15:31 .. drwxrwx--- 2 jturner mail 4096 May 16 15:18 cur -rw-rw-rw- 1 support mail 448 May 16 15:32 dovecot.index -rw-rw-rw- 1 support mail 21504 May 16 15:32 dovecot.index.cache -rw-rw-rw- 1 support mail 512 May 16 15:32 dovecot.index.log -rw------- 1 support mail 72 May 16 15:28 dovecot-keywords -rw-rw-rw- 1 jturner mail 0 May 16 14:52 dovecot-shared -rw-rw-rw- 1 support mail 516 May 16 15:32 dovecot-uidlist drwxrwx--- 2 jturner mail 4096 May 16 15:01 new drwxrwx--- 2 jturner mail 4096 May 16 15:14 tmp root@redback:/imap/mailboxes/support/.INBOX.test# - If I now log in as 'jturner' and subscribe to this folder, there appears to be nothing in the 'test' folder.

[Dovecot] IMAP Folder Creation
by Zach Hobbs 23 May '06

23 May '06

I am using Maildir with dovecot 0.99.14-1 and postfix. My IMAP server was working where I could create a folder in Kmail or Thunderbird and specify wether the folder was to hold messages or folders. Then something changed, and I lost all my folders that contained sub-folders. And now I cannot create folders that contain subfolders (Kmail doesn't event give the option anymore). I can create folders and put messages in them, but I cannot create subfolders in the newly created folders. The Maildir is owned by the user logging in. Do I need to do anything with permissions, or are there settings to allow/disallow this? I've been reading through everything I could find with dovecot and folders in the message, and I can't come up with anything. Here's an example file structure (logging in as "zta-tech_zach"): Maildir# ls -lA -R .: total 32 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:41 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:16 .customflags -rw------- 1 zta-tech_zach web1 52 2006-05-22 21:40 dovecot-uidlist drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:16 .INBOX drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 new -rw------- 1 zta-tech_zach web1 6 2006-05-22 21:41 .subscriptions drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:40 tmp drwx------ 5 zta-tech_zach web1 4096 2006-05-22 21:25 .Trash ./cur: total 20 -rw------- 1 zta-tech_zach web1 16591 2006-05-22 21:40 1148352021.3157_1.www.zta-tech.com:2,S ./.INBOX: total 24 -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:41 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:16 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:16 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:16 .imap.index.tree ./new: total 0 ./tmp: total 0 ./.Trash: total 40 drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 cur -rw------- 1 zta-tech_zach web1 5 2006-05-22 21:25 .customflags -rw------- 1 zta-tech_zach web1 1608 2006-05-22 21:24 .imap.index -rw------- 1 zta-tech_zach web1 10264 2006-05-22 21:25 .imap.index.data -rw------- 1 zta-tech_zach web1 2576 2006-05-22 21:25 .imap.index.log -rw------- 1 zta-tech_zach web1 1560 2006-05-22 21:25 .imap.index.tree drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 new drwx------ 2 zta-tech_zach web1 4096 2006-05-22 21:24 tmp ./.Trash/cur: total 0 ./.Trash/new: total 0 ./.Trash/tmp: total 0 Thanks, Zach

[Dovecot] Dovecot IMAP not putting size in maildir filenames
by Bill Boebel 23 May '06

23 May '06

I notice that when you move a message from one maildir folder to another, Dovecot drops the size information ("S=") from the filename. Dovecot also does not add the size info to filenames after it gets it via stat(). Shouldn't Dovecot add the size info to the filename so that "maildirsize" recalculations are fast? Bill

[Dovecot] mountpoint_get broke the quota plugin
by Bill Boebel 23 May '06

23 May '06

Looks like the new mountpoint_get code broke the quota plugin. I am getting this error when trying to start dovecot, using last night's CVS on Red Hat ES3: # service dovecot start Starting Dovecot Imap: Edlopen(/usr/lib/dovecot/imap/lib01_quota_plugin.so) failed: /usr/lib/dovecot/imap/lib01_quota_plugin.so: undefined symbol: mountpoint_get Error: imap dump-capability process returned 22784 [FAILED] Bill

[Dovecot] Fatal: sigaction(SIGRTMIN) failed: Invalid argument

Hello, I just download dovecot 1.0b8 and compiled and installed from sources. After setting some default configurations, here's what I get: [root@ba root]# dovecot [root@ba root]# Fatal: sigaction(SIGRTMIN) failed: Invalid argument Here`s my configuration: # Base directory where to store runtime data. base_dir = /var/run/dovecot/ # Protocols we want to be serving: # imap imaps pop3 pop3s protocols = imap protocol imap { listen = *:10143 # ssl_listen = *:10943 # .. } # Disable SSL/TLS support. ssl_disable = yes # Use this logfile instead of syslog(). /dev/stderr can be used if you want to # use stderr for logging (ONLY /dev/stderr - otherwise it is closed). log_path = /dev/stderr # For informational messages, use this logfile instead of the default info_log_path = /var/log/dovecot-info.log # everything in this directory is deleted when Dovecot is started. login_dir = /var/run/dovecot/login # default_mail_env = maildir:/var/mail/%1u/%u/Maildir default_mail_env = mbox:/home/webmail/:INBOX=/var/spool/mail/%u auth default { # Space separated list of wanted authentication mechanisms: # plain login digest-md5 cram-md5 ntlm rpa apop anonymous gssapi mechanisms = plain # /etc/passwd or similar, using getpwnam() # In many systems nowadays this uses Name Service Switch, which is # configured in /etc/nsswitch.conf. userdb passwd { } user = root } This is really weird.

[Dovecot] two concurrent dovecots
by Alexey Koptsevich 20 May '06

20 May '06

Hello, Is it safe to have two concurrent dovecot processes to access the same maildir? I have a stock RHEL version (0.99.11) used by users, but I also want to test 1.0-beta together wth postfix for SASL. Is it safe to access the same maildir concurrently with both dovecots (say, the old one via webmail and the new one via remote client)? Thanks, Alex

[Dovecot] Dovecot/LDAP problem
by Burton Simmons 19 May '06

19 May '06

Dear Dovecot mailing list people - What I'm trying to do is use Postfix (with virtual users) and a POP3 server (we don't want IMAP - don't ask) to work against our new Active Directory servers that will be coming soon. Before we roll anything out we're testing it in the lab. Here's what we've got: x86 server running Red Hat Enterprise Linux 3 Postfix 2.0.16 Dovecot-1.0 Beta7 Windows 2003 server running Active Directory Windows XP client running Outlook Eventually, we'd like the clients to be joined to the AD domain and that's where we'll store ALL the user information. The email will come in on our postfix server (which uses virtual users) and the clients will check it passing their email username and domain password. The catch is that USERS CAN BE ANYWHERE IN THE DIRECTORY. (I apologize for the caps, I wanted to make sure that phrase wasn't glossed over.) So, for instance: > DC=local | >DC=domain | >OU=group1 | | | > CN=user1 | > CN=user2 | >OU=group2 | | | > CN=user3 | > CN=user4 | >OU=group3 | >CN=user5 The path to user1 is therefore CN=user1,OU=group1,DC=domain,DC=local (at least in the AD world.) The path to user3 is CN=user3,OU=group2,DC=domain,DC=local. So to search for users I would think (because this is how Postfix does it) that I could have the search base as DC=domain,DC=local and then have scope = subtree. IT DOESN'T WORK. (Again, caps used for emphasis only.) Here's the meat of the dovecot-ldap.conf file I'm using: hosts = 192.168.x.x dn = cn=Administrator,cn=Users,DC=domain,DC=local dnpass = xxxxx auth_bind = yes ldap_version = 3 base = DC=domain,DC=local scope = subtree user_attrs = sAMAccountName,mail,,,, user_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) pass_filter = (&(objectClass=organizationalPerson)(sAMAccountName=%u)) user_global_uid = 44 user_global_gid = 44 --- Interestingly, if I simply point the base to the actual user's container, it works just fine. The idea works from Postfix, but from dovecot it doesn't actually seem to search the tree. --- Here's some of the output from the log files. dovecot: May 17 15:35:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip= 192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:35:52 Info: auth(default): ldap(user1, 192.168.0.195): bind search: base=DC=LAB,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:36:52 Info: pop3-login: Disconnected: Inactivity: method=PLAIN, rip= 192.168.90.195, lip=192.168.90.199 dovecot: May 17 15:37:52 Info: auth(default): client in: AUTH 1 PLAIN service=POP3 lip=192.168.0.199 rip=192.168.0.195 resp=AGp1c2VyAHBhc3N3b3Jk dovecot: May 17 15:37:52 Info: auth(default): ldap(user1,192.168.0.195): bind search: base=DC=domain,DC=local filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): client out: OK 1 user=user1 dovecot: May 17 15:37:54 Info: auth(default): master in: REQUEST 1 25233 1 dovecot: May 17 15:37:54 Info: auth(default): ldap(user1,192.168.0.195): base=DC=LAB,DC=local scope=subtree filter=(&(objectClass=organizationalPerson)(sAMAccountName=user1)) fields=sAMAccountName,mail,,,, dovecot: May 17 15:38:52 Info: pop3-login: Disconnected: Inactivity: user=<user1>, method=PLAIN, rip=192.168.0.195, lip=192.168.0.199 Can anybody offer any insight?

[Dovecot] configure change for 1.0.beta8
by Tomi Vainio 19 May '06

19 May '06

Hi, I'm trying to compile dovecot under Solaris 10 with native Mysql support. Couple changes are needed before configure can detect and compile mysql support. Native Solaris Mysql is installed under /usr/sfw directory. Configure can't find libraries and when these are found -R runtime path is needed for linking. Also if library name is given before library path it can't find it. These changes are needed for configure script line 29533 for i in /usr /usr/local /usr/local/mysql /usr/sfw; do line 29548 LIBS="$LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29559 LIBS="$LIBS -lmysqlclient" line 29770 SQL_LIBS="$SQL_LIBS -L$MYSQL_LIBDIR -R$MYSQL_LIBDIR" line 29780 LIBS="$LIBS -lmysqlclient" Tomppa

[Dovecot] Outlook Express / POP Problem?
by Marc Perkel 19 May '06

19 May '06

I have a new user who is using Outlook Express with POP and seems to be having a problem downloading messages with attachments. Watching the logs it starts to download and then disconnects. When I use squirrelmail which is IMAP it all looks good so it's not a corrupt mailbox. I'm running Beta8 and using MBOX files. The problem seems to be related to POP and/or Outlook. Has anyone run into this before?

I don't think this is the correct fix below, but it did the trick in our environment when maildir_copy_with_hardlinks=yes. I think the real problem is that quota_default_alloc() is getting called twice. Once from somewhere in mail_storage_copy() -> maildir_copy() -> mailbox_save_init(), and a second time somewhere after that. src/lib-storage/index/maildir/maildir-copy.c @136 < if (mbox->storage->copy_with_hardlinks/* && < mail->box->storage == mbox->ibox.box.storage*/) { --- > if (mbox->storage->copy_with_hardlinks) {

The following patch is needed on Solaris, because <sys/stat.h> has a specific macro definition for struct stat. Without this patch the prototype for nfs_safe_stat() changes between the inclusion of nfs-workarounds.h and the definition of the function. -- Matthieu Herrb
