[Dovecot] Released Pigeonhole v0.4.1 for Dovecot v2.2.4.
by Stephan Bosch 03 Jul '13

03 Jul '13

Hello Dovecot users, Now that I am not preoccupied anymore, I quickly release a new version of Pigeonhole for Dovecot v2.2. This consists mainly of bug fixes. One new feature is that the Sieve plugin will try to pass temporary failures (e.g. from mail storage) back to LDA/LMTP as much as possible. However, this change turned out a little bigger than I would have liked, so experiment with it a bit before you deploy it in production. Changelog v0.4.1: + Added support for handling temporary failures. These are passed back to LDA/LTMP to produce an appropriate response towards the MTA. - Sieve storage: Removed PATH_MAX limitation for active symlink. This caused problems for GNU/Hurd. - Fixed line endings in X-Sieve headers added by redirect command. - ManageSieve: Fixed '[' ']' stupidity for response codes (only happened before login). - Fixed setting name in example-config/conf.d/20-managesieve.conf. - Sieve extprograms plugin: Fixed interaction between pipe command and remote script service. The output from the script service was never read, causing a broken pipe error at the script service. Apparently, this was broken since the I/O handling for extprograms was last revised. - Fixed assertion failure due to datastack problem in message header composition. The release is available as follows: http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.1.tar.gz http://www.rename-it.nl/dovecot/2.2/dovecot-2.2-pigeonhole-0.4.1.tar.gz.sig Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for more information. Have fun testing this new release and don't hesitate to notify me when there are any problems. Regards, -- Stephan Bosch stephan(a)rename-it.nl

[Dovecot] Creating an authenticated user master user
by Chris Bullock 03 Jul '13

03 Jul '13

dovecot --version 1.1.18 mbox format We are trying to migrate from dovecot to another imap server and need some help migrating the user data to the new server. We have written a perl script to migrate the data but it seems that we need an "authenticated or Master user" in order for the script to access the user mail boxes without the users password. We are using PAM authentication, and root does not have access to the user's mail boxes. Any help would be appreciated. Chris

[Dovecot] Who all accessed my dovecot server?
by pvsuja 03 Jul '13

03 Jul '13

Hi, I have set up a mail server with dovecot as IMAP/POP3 server, postfix as MTA and roundcube as web mail client. Other mail clients such as Thunderbird is also being used for mail access. Now as a security policy in our organization, I want to know the IP addresses of the machines from which my mail server was accessed. Is there any monitoring tools to get these details? Regards, Suja -- View this message in context: http://dovecot.2317879.n4.nabble.com/Who-all-accessed-my-dovecot-server-tp4… Sent from the Dovecot mailing list archive at Nabble.com.

Hi I came across this error which happend immedately after a mail delivery to the inbox. Should I look for the problem externally to dovecot (ie. file system, operating system) or within dovecot?

[Dovecot] IMAPS: Disable SSL connection without client certificate
by Ireneusz Szcześniak 02 Jul '13

02 Jul '13

I've been using Dovecot 2.1.8 on OpenBSD 5.2 i386 for about a month. It works great. Dovecot serves IMAPS only, and I'm using Thunderbird to access my mail. I configured Dovecot to allow clients that present a valid certificate when establishing SSL connection. I configure my Thunderbird for SSL/TLS connection with normal password. It works fine. However, with my config anybody can connect to my server without presenting a certificate: > openssl s_client -connect server:993 > (...) > * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS > ID ENABLE IDLE AUTH=PLAIN] Dovecot ready. Luckily, after connecting without a certificate logging fails: > a001 login iszczesniak password > a001 NO [ALERT] Client didn't present valid SSL certificate *QUESTION: Is there a way in Dovecot to disable establishing an SSL connection without a client certificate?* My complete config is : # dovecot -n # 2.1.8: /etc/dovecot/dovecot.conf # OS: OpenBSD 5.2 i386 auth_ssl_require_client_cert = yes mail_location = maildir:~/archive/mail mbox_write_locks = fcntl mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Sent { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = bsdauth } protocols = imap service imap-login { inet_listener imap { port = 0 } } ssl_ca = </etc/ssl/certs/cacertcrl.pem ssl_cert = </etc/ssl/cert.pem ssl_key = </etc/ssl/private/key.pem ssl_verify_client_cert = yes userdb { driver = passwd } verbose_ssl = yes protocol imap { imap_client_workarounds = delay-newmail tb-extra-mailbox-sep tb-lsub-flags } protocol pop3 { pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } -- Ireneusz (Irek) Szczesniak http://www.irkos.org

[Dovecot] Doubt the relationship between NTLM and Kerberos.
by Maria Jose Yañez Dacosta 01 Jul '13

01 Jul '13

Could someone explain to me what role does the Authenticating Kerberos NTLM in Authenticating NTLM explained in http://wiki.dovecot.org/HowTo/ActiveDirectoryNtlm ? Not understand that relationship between NTLM and Kerberos?. I have to configure thunderbird with simple password method and leave the password to be blank or have to use the gssapi? Although gssapi not supported by windows right? You have to generate a keytab for imap server against AD? I should create in windows and copy it to linux where I have my imap server? I appreciate someone can explain this. Thank you!. -- Maria José

The password field > in your query is userPassword or am I wrong here? the password field is hidden (only the user can see it) by default, and not stored as a unix-friendly value (anything a crypt() would understand) what I use is auth_bind (which uses user-supplied password to bind to the LDAP directory). what it means is that on every login there are 2 lookups (first one using your "service" DN to find the user DN, second one with your user DN to check the password) that also means that you need a password format that your LDAP can understand (mostly a plaintext password, or NTLM if your mail server is a Samba domain member). As long as you only offer IMAP/SSL I dont think plaintext (as in "auth_mechanisms = plain") is an issue, security wise. as far as the service account (the one that is used to look up users) goes, I am using the default option (setting "dn" and "dnpass" variables), which I think is a simple bind. it is possible that it only works because Samba4 and dovecot run on the same machine.

[Dovecot] Samba4 and user auth

[Dovecot] LIST command -- quoting of folder names
by Eric Abrahamsen 01 Jul '13

01 Jul '13

If I open an imap connection to a local maildir installation like so: /usr/lib/dovecot/imap -o mail_location=maildir:$HOME/.mail/account/:LAYOUT=fs And issue: c list "" * This is the result (this is a gmail account): * LIST (\HasChildren) "/" [Gmail] * LIST (\HasNoChildren) "/" [Gmail]/Spam * LIST (\HasNoChildren) "/" [Gmail]/Starred * LIST (\HasNoChildren) "/" [Gmail]/Trash * LIST (\HasNoChildren) "/" [Gmail]/Drafts * LIST (\HasNoChildren) "/" "[Gmail]/Sent Mail" * LIST (\HasNoChildren) "/" [Gmail]/Important * LIST (\HasNoChildren) "/" INBOX Only "[Gmail]/Sent Mail" is quoted. This is messing up gnus, my MUA, which truncates other folder names after the / separator. Examples of testing I've seen online have shown all folder names quoted, which would allow things to work correctly here. Is this something I can affect with local configuration, or is there some other solution? Would removing "LAYOUT=fs" affect this issue? Thanks!

[Dovecot] Issues when compiling dovecot antispam on debian wheezy
by Joan 28 Jun '13

28 Jun '13

I've been trying to compile the latest version of dovecot-antispam, and it doesn't work, the latest patch fixes compilation for dovecot versions greater than 2.1.16 but the packaged version in debian is 2.1.7 and doesn't provide the DOVECOT_PREREQ macro. It seems there are some solutions: 1) Rollback to the last working version so it can be used on wheezy 2) Open a bug report in debian to see if they can backport the macro here ( http://www.dovecot.org/list/dovecot-cvs/2013-March/022903.html) 3) Use the packaged version from debian 4) .. What's your opinion?

[Dovecot] Zero-sized Maildir files and index corruption on over-quota
by Edgar Fuß 28 Jun '13

28 Jun '13

We are using Postfix as an MTA delivering via Dovecot's LDA (with sieve). We also use Dovecot as a POP/IMAP server. Mail storage is Maildir on NFS, indexes are stored locally. Quotas are FS quotas enforced by the NFS server. The Dovecot version is 1.2.11. Recently, for one user being over quota, some attempts to deliver mail bounced as expected while some others resulted in zero-sized Maildir files. I can verify zero-sized files in cur, while I cannot tell whether they were already zero-sized in new. However, since nobody except Dovecot is accessing the mail storage, it's either Dovecot's LDA or Dovecot's IMAP producing the zero-sized files. Logs show successful delivery (deliver: stored mail into mailbox 'INBOX') but ,,Corrupted index cache file /var/db/dovecot/indexes/XXX/.INBOX/dovecot.index.cache: Corrupted virtual size for uid=YYY: 0 != NNNN'' alerts on IMAP access. It looks like all mails which correctly got bounced are >64KB while those resulting in zero-sized files are <64KB (there is one >32KB). My first guess would be that maybe for large files, write() fails, while for small ones, close() fails or there is some buffering involved for large files.

[Dovecot] traffic statistics

Ideally this would be able to filter per domain, too. ;-) Thanks a lot, Martin -- Martin Waschbüsch IT-Dienstleistungen Lautensackstr. 16 80687 München Telefon: +49 89 57005708 Fax: +49 89 57868023 Mobil: +49 170 2189794 martin(a)waschbuesch.de http://martin.waschbuesch.de

[Dovecot] Dovecot NTLM Authentication
by Matthew Larsen 27 Jun '13

27 Jun '13

I'm working on getting authentication for Postfix smtpd clients working with Dovecot. I've got both plain text and GSSAPI mechanisms working. Winbind also works for shell access and the command line test work fine. If I can get NTLM authentication working I can use Postfix as a drop in replacement for a MS MTA I want get rid of. I'm hoping the community might be able to offer some insight into what I'm missing to get NTLM authentication working with Dovecot and Postfix. Something related to winbind I suspect. When I use the NTLM mechanism I get this " auth: Debug: client out: FAIL#0112" message in my maillog file. Nothing seems to show up in the winbind files for this. ---- log file from NTLM mechanism used ---- Jun 26 17:02:53 SBSMTPNV05 postfix/smtpd[2221]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0112#011NTLM#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=TlRM...A= Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0112#011TlRM....A Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0112#011TlRM....Q= Jun 26 17:02:53 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 26 17:02:55 SBSMTPNV05 postfix/smtpd[2221]: warning: nvit01b.mydomain.com[10.20.2.0]: SASL NTLM authentication failed: TlRM....A Jun 26 17:02:55 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0112 Jun 26 17:02:59 SBSMTPNV05 postfix/smtpd[2221]: disconnect from nvit01b.mydomain.com[10.20.2.0] ------------------------------------------ ---- log file from GSSAPI mechanism used ----- Jun 26 17:02:08 SBSMTPNV05 postfix/smtpd[2221]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 26 17:02:08 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=2221) Jun 26 17:02:08 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011GSSAPI#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=YIIN....

Dear Team, Due to some reasons I need to move vmail folder to another drive. I tried to do rsync & I was able to copy all the files and structure with same old date and time stamp. I made symbolic link and new mail flow was fine but problem is, all the mail boxes started downloading old mails again . Is there any way where I can copy location of the folder without this problem.

[Dovecot] How to manage email with an ISP restricted mailbox size?
by Tom Atkins 26 Jun '13

26 Jun '13

Sorry if this is a bit off topic but I'm hoping list members here might have some ideas. Aim: use ISP provided email with restricted inbox size but keep an IMAP accessible archive of emails (including 'sent' messages) on a remote server. Scenario: - Don't want to run my own SMTP server - Have free ISP email with 1Gb mailbox limit and spam filtering that works well - Have remote server with plenty of disk space - Want to use remote server for IMAP access to archive of email to avoid 1Gb ISP mailbox limit Options I tried: 1. Use ISP email via IMAP and periodically backup / archive messages to remote server with something like mbsync / isync to maildir format. Delete old messages on ISP server safe in knowledge they are backed up on my server. QUESTION: how to access those archives via IMAP (read only is OK)? 2. Use ISP email for sending messages only. Use Getmail / Fetchmail to move messages to remote server and run Dovecot there. I tried using Getmail to do this but couldn't figure out how to keep copies of 'Sent' and 'Draft' messages if the email client was configured to read via IMAP on one server and send via SMTP to another server. Any thoughts on how best to achieve my aims? Thanks, Tom.

[Dovecot] Help installing Dovecot 1.0 on Debian 6.0.7

Hi, Could someone please let me know if I can get the pre-built binaries for Dovecot 1.0 for Debian 6.0? If I do "apt-get install dovecot...", I am getting Dovecot v1.2.5 installed, but it doesn't like the existing Dovecot 1.0 configuration I have, and due to some urgency, I am trying to avoid migrating the configuration to the new structure / requirements.

[Dovecot] Dovecot 2 and managesieve
by Darek 25 Jun '13

25 Jun '13

Having some difficulty finding out whether managesieve is still a separate package (not seeing it in the FreeBSD ports tree, only one for 1.x) or whether it was integrated into the main 2.x package. I've only been using 1.2.x up to now, and trying to document a system install. So is it in the main distribution now? -- Darek

[Dovecot] NTLM Authentication with Dovecot and Postfix
by Matthew Larsen 25 Jun '13

25 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism via Dovecot and winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method.

[Dovecot] Configuring TLS 1.2
by Phillip Odam 25 Jun '13

25 Jun '13

Hi I'm running dovecot 2.1.6 and am trying to configure it to require TLS 1.2. So far I've only got as far as getting TLS 1.0 going. In the config file <dovecot root>/etc/dovecot/conf.d/10-ssl.conf, I've tried setting ssl_protocols to values like TLSv1.2:!TLSv1:!SSL3 but without any success. Attempts to google this matter turns up results for dovecot v1.2 as opposed to configuring TLS 1.2 in dovecot And having a look over the mailing list archive hasn't turned anything up thus far. Any pointers would be greatly appreciated. Thanks Phillip

[Dovecot] Sieve file permission problem
by Zoltan Lippai 25 Jun '13

25 Jun '13

Hi folks, I am using dovecot 2.1.7 with the ManageSieve plugin which works great. Recently I set up Afterlogic webmail on my server (the community version) and it has a nice UI to manage the sieve settings. It uses port 2000 to communicate with dovecot via the ManageSieve plugin. Also, dovecot uses Maildirs to store the messages. The problem is that the permissions on the files that store the sieve rules are to strict. I am talking about the "sieve" directory and the .dovecot.sieve file. The sieve folder has a chmod 700 and the .dovecot.sieve is chmod 600. Both are owned by vmail:mail If I delete these two items, then the rules can be saved via the web interface. Then these files are created but for some reason the ManageSieve plugin can't modify them. Here is the output of dovecot -n: http://pastebin.com/4eqyBKCA Can you help me out on this? Thanks a lot! Zoltan

[Dovecot] Quota based on LDAP group
by Pavel Herrmann 25 Jun '13

25 Jun '13

Hi I have a setup where my dovecot (2.0, if that makes a difference) authenticates against an LDAP directory. In my scenario, I have two types of users, lets call them "normal" and "privileged". What I need is for the normal user to have a fixed quota, but for the priviledged to have none. (The users do not exist on the underlying system, so I cant do quota based on FS) The issue is that my LDAP is actually an AD, and there is a fair amount of new accounts over the time (in other words, I cannot use LDAP attribute for storing quota, because the AD tools don't understand it, and I would have to add it manually for each new account). The approach I had in mind is using quota based on user group (I do have groups representing both normal and priviledged users), but I cannot find a way to set it up in dovecot. Am I missing something or does dovecot not support LDAP groups as attribute source? thanks Pavel Herrmann

[Dovecot] Warning recipient when message delivery fails due to over-quota
by Ben Johnson 24 Jun '13

24 Jun '13

I'm working to configure automated quota notifications in Dovecot and am wondering if it is possible to send a warning message to a user when message delivery fails because the user is over-quota. I already have the following directives configured: quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d These seem to function as expected, but the problem I'm facing is that when a message is large enough to take the user's quota from, say, 84% to over 100%, the message is rejected (as expected), but the user is never warned that a message failed to be delivered because it would have put him over 100% usage. I suppose that I'm looking for a trigger that is tripped when delivering the message *would* put the user over-quota (as opposed to *does in fact* put the user over). The sender receives an automated rejection message already. I'm wondering if the recipient can be warned at the same time. (I'm not concerned about further increasing the user's quota consumption with the warning message; I would set noenforcing to 1.) Is this possible? Any help is much appreciated. Thanks in advance. -Ben

Hi, I am looking for a way to sync only selected files/mailbox'es using dsync. Am I using the dsync -m option incorectly? It looks like it's being ignored.

[Dovecot] dovecot-lda - dovecot: quota-warning: Error: lda: Fatal: Unknown argument
by Ben Johnson 24 Jun '13

24 Jun '13

Hi, everyone, I'm attempting to configure automated quota warnings for users and have hit a snag. The script I'm using is as follows: --------------------------------------------------------------------- #!/bin/sh PERCENT=$1 MAILBOX=$2 DOMAIN=$3 cat << EOF | /usr/lib/dovecot/dovecot-lda -d $USER -o "plugin/quota=dict:user::file:/var/vmail/%d/%n/.quotausage" From: postmaster@$DOMAIN Subject: Email quota warning - mailbox over $PERCENT% full [...] --------------------------------------------------------------------- When the script is triggered, here's what appears in the log: --------------------------------------------------------------------- Jun 24 11:16:53 host dovecot: quota-warning: Error: lda: Fatal: Unknown argument: plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage Jun 24 11:16:53 host dovecot: master: Error: service(quota-warning): child 22415 returned error 64 --------------------------------------------------------------------- If I paste the same on the command line, the message is delivered, as expected: /usr/lib/dovecot/dovecot-lda -d user(a)example.com -o "plugin/quota=dict:user::noenforcing:file:/var/vmail/%d/%n/.quotausage" -p /tmp/test.txt The problem seems to be that the -o switch isn't being interpreted correctly when dovecot-lda is called from within the script. -o is the correct switch, yes? From the manual at http://wiki2.dovecot.org/LDA : -o name=value: Override a setting from dovecot.conf. You can give this parameter multiple times. What am I missing here? Is some shell script escaping or similar required? Thanks for any tips! -Ben

[Dovecot] NTLM Authentication for Postfix SMTP clients
by Matthew Larsen 24 Jun '13

24 Jun '13

I'm trying to get NTLM authentication working with Dovecot to authenticate Postfix SMTP clients. I can authenticate postfix smtp clients using the plain text login mechanism through winbind. However, using the NTLM mechanism gives me an error in my maillog that says: "dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL". At this point, I'm rather stuck. It appears PAM and winbind work for authenticating with AD because it works with the plain text mechanism, but I'm missing something with the NTLM authentication method. Any suggestions as to what I've got wrong, or other logging I can turn up / examine that might shed some light on this? When I use the LOGIN mechanism I see this in the mail logging and the message is relayed: Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1501) Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011PLAIN#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=AG[...snip...]g== Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): lookup service=dovecot Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: pam(myusername,10.20.2.0): #1/1 style=1 msg=Password: Jun 21 13:12:58 SBSMTPNV05 dovecot: auth: Debug: client out: OK#0111#011user=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: 54EAF8059B: client=nvit01b.mydomain.com[10.20.2.0], sasl_method=PLAIN, sasl_username=myusername Jun 21 13:12:58 SBSMTPNV05 postfix/cleanup[1504]: 54EAF8059B: message-id=<51C4B3C8.30008(a)domain1.com> Jun 21 13:12:58 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: from=<someone(a)domain1.com>, size=2700, nrcpt=1 (queue active) Jun 21 13:12:58 SBSMTPNV05 postfix/smtpd[1501]: disconnect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:12:59 SBSMTPNV05 postfix/smtp[1505]: 54EAF8059B: to=<someone(a)gmail.com>, relay=gmail-smtp-in.l.google.com[74.125.25.27]:25, delay=1.2, delays=0.23/0.04/0.16/0.72, dsn=2.0.0, status=sent (250 2.0.0 OK 1371845579 wf5si3786287pab.138 - gsmtp) Jun 21 13:12:59 SBSMTPNV05 postfix/qmgr[1499]: 54EAF8059B: removed I also see this in the secure log: Jun 21 13:12:58 SBSMTPNV05 auth: pam_unix(dovecot:auth): authentication failure; logname= uid=0 euid=0 tty=dovecot ruser=myusername rhost=10.20.2.0 user=myusername Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): getting password (0x00000010) Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): pam_get_item returned a password Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:auth): user 'myusername' granted access Jun 21 13:12:58 SBSMTPNV05 auth: pam_winbind(dovecot:account): user 'myusername' granted access However, when I switch the mechanism to NTLM in the Thurnderbird MUA I see this: Jun 21 13:15:46 SBSMTPNV05 postfix/smtpd[1506]: connect from nvit01b.mydomain.com[10.20.2.0] Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Loading modules from directory: /usr/lib64/dovecot/auth Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libauthdb_ldap.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libdriver_sqlite.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: Module loaded: /usr/lib64/dovecot/auth/libmech_gssapi.so Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: auth client connected (pid=1506) Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: AUTH#0111#011NTLM#011service=smtp#011nologin#011lip=10.20.4.12#011rip=10.20.2.0#011resp=TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client out: CONT#0111#011TlRMT[[...snip...]A Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: Debug: client in: CONT#0111#011TlRMT[...snip...]A= Jun 21 13:15:46 SBSMTPNV05 dovecot: auth: winbind(?,10.20.2.0): user not authenticated: NT_STATUS_UNSUCCESSFUL Jun 21 13:15:48 SBSMTPNV05 postfix/smtpd[1506]: warning: nvit01b.mydomain.com[10.20.2.0]: SASL NTLM authentication failed: TlRMT[...snip...]A Jun 21 13:15:48 SBSMTPNV05 dovecot: auth: Debug: client out: FAIL#0111 Jun 21 13:15:49 SBSMTPNV05 postfix/smtpd[1506]: disconnect from nvit01b.mydomain.com[10.20.2.0] with nothing in the secure log and I don't see anything show up in the winbind logs either.

[Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect
by Ben Johnson 24 Jun '13

24 Jun '13

Hello, I'm attempting to configure the Dovecot Antispam plug-in on Ubuntu 12.04 LTS with Dovecot 2.0.19. Everything seems to be in order with one considerable exception: when my pipe script (a simple Bash shell script) calls the dovecot-lda executable, absolutely nothing seems to result. If I copy/paste the exact same command into the terminal, the mail is delivered to the target mailbox, as expected. Here's my pipe script: http://pastebin.com/DBXAZqsN When I move a message from INBOX -> Junk, or from Junk -> INBOX, the pipe script is called, and here's the output: --------------------------------------------------------------- 31465-start (--debug --username=amavis --ham) Checking if the command-line input argument string (--debug --username=amavis --ham) contains the string "ham" or "spam" Mode is "HAM" Calling (as user vmail) '/usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt"' 31465-end --------------------------------------------------------------- But, for some reason, the call to "/usr/lib/dovecot/deliver" doesn't seem to do anything. If I copy the above output and paste it into the terminal: /usr/lib/dovecot/deliver -d "sa-training(a)example.com" -m "Training.HAM" -p "/tmp/sendmail-msg-31465.txt" Dovecot does indeed deliver the message. This works whether I execute the above command as "root" or "vmail". Why does this command have no effect when called from within the pipe script? Here is my "doveconf -n" output: # 2.0.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-042stab076.8 x86_64 Ubuntu 12.04.2 LTS auth_mechanisms = plain login disable_plaintext_auth = no listen = *,[::] log_timestamp = "%Y-%m-%d %H:%M:%S " mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { antispam_backend = pipe antispam_debug_target = syslog antispam_pipe_program = /usr/bin/sa-learn-pipe.sh antispam_pipe_program_args = --debug;--username=amavis antispam_pipe_program_notspam_arg = --ham antispam_pipe_program_spam_arg = --spam antispam_pipe_tmpdir = /tmp antispam_spam_pattern_ignorecase = SPAM;JUNK antispam_trash_pattern_ignorecase = trash;Deleted * antispam_verbose_debug = 1 quota = dict:user::file:/var/vmail/%d/%n/.quotausage quota_rule2 = Trash:storage=+100M quota_rule3 = Junk:ignore quota_warning = storage=95%% quota-warning 95 %u %d quota_warning2 = storage=80%% quota-warning 80 %u %d quota_warning3 = -storage=100%% quota-below below %u %d sieve = /var/vmail/%d/%n/.sieve } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service quota-below { executable = script /usr/local/bin/quota-below.sh user = vmail } service quota-warning { executable = script /usr/local/bin/quota-warning.sh user = vmail } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota antispam } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { info_log_path = /var/log/dovecot-lda.log log_path = /var/log/dovecot-lda-errors.log mail_plugins = sieve quota } Thank you, -Ben

[Dovecot] Dovecot + SELinux permission problems
by Johnny 24 Jun '13

24 Jun '13

Hi, I have set-up dovecot on a F17 box and am encountering weirdnesses with SELinux (who isn't??). Again, I am trying to refrain from disabling SWLinux all together, however tempting, but am stuck in troubleshooting and hope for some ideas...

[Dovecot] tables between dovecot and postfix and a paradoxical question
by Mohsen Pahlevanzadeh 23 Jun '13

23 Jun '13

Dear all, I read we create the following table in wiki2 : CREATE TABLE users ( userid VARCHAR(128) NOT NULL, domain VARCHAR(128) NOT NULL, password VARCHAR(64) NOT NULL, home VARCHAR(255) NOT NULL, uid INTEGER NOT NULL, gid INTEGER NOT NULL ); But i read the following text in the official postfix documentation : "DO create tables with each matching item as a key and with an arbitrary value. With SQL databases it is not uncommon to return the key itself or a constant value." ref: http://www.postfix.org/mysql_table.5.html How can i combine together? --mohsen

[Dovecot] Problem with virtual user mailbox initialization
by Denis Kasak 22 Jun '13

22 Jun '13

Hello, I'm trying to set up a postfix/dovecot server where postfix hands over incoming mail to dovecot using lmtp virtual transport via a Unix socket. Dovecot is then supposed to write the mail to /var/mail/<domain>/<user>/ using a virtual users setup. It seems to work except for failing when the mailbox is supposed to be initially created: Jun 22 03:25:04 lmtp(2400, dkasak(a)foo.org) Error: user dkasak(a)foo.org: Initialization failed: Namespace '': mkdir(/var/mail/foo.org/dkasak) failed: Permission denied (euid=5000(postman) egid=5000(postman) missing +w perm: /var/mail, we're not in group 6(mail), dir owned by 0:6 mode=0775) As can be seen from the error message, I've set mail_uid and mail_gid to account/group postman. /var/mail/ is empty and owned by root:mail so I've also set mail_privileged_group = mail. I was under the impression that mail_privileged_group is used precisely for these situations (when dotlocking or initial creation of the mailbox fail due to insufficient privileges), but it still doesn't work. If I either set mail_gid = mail, or set mail_access_groups = mail, or create foo.org/ owned by postman:postman by hand, it works as expected. Here is the complete configuration: # 2.2.2: /usr/local/etc/dovecot/dovecot.conf # OS: FreeBSD 9.1-RELEASE-p4 i386 ufs base_dir = /var/run/dovecot/ mail_gid = postman mail_location = maildir:/var/mail/%d/%n/:LAYOUT=fs mail_privileged_group = mail mail_uid = postman managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave 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 = separator = / type = private } passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = imap lmtp service auth-worker { user = $default_internal_user } service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } service imap-login { inet_listener imap { port = 143 } } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0660 user = postfix } } ssl = required ssl_cert = </etc/ssl/certs/dovecot.pem ssl_key = </etc/ssl/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users default_fields = quota_rule=*:storage=2G driver = passwd-file } protocol imap { mail_plugins = " notify mail_log" } Any ideas? -- Denis Kasak

Re: [Dovecot] Calling dovecot-lda from within Antispam pipe script (bash) seems to have no effect

My script now outputs the following: > ... > CONFIG_FILE=/var/run/dovecot/config > ... > Does anything jump-out at you? You didn't provide the analogous output from the interactive shell to see the differences (for example, USER might be being used), but from your later strace, I guess CONFIG_FILE has something to do with it. These threads seems relevant http://www.dovecot.org/list/dovecot/2011-May/059127.html http://www.mail-archive.com/dovecot@dovecot.org/msg38349.html That thread poster solved his problem by commenting out service imap-postlogin { # user = $default_internal_user ... } but I have no idea if it works, or whether it's a good idea, for your case.
